The best Güde dirty water pumps, compared.

A dirty water pump is a mains submersible for a short drain of sandy or muddy water, such as a cooled hot tub, a pond or a cellar. It is not a sprinkler and not a sewage pump. You recognise a suitable one by the particle limit, the maximum head, and how much water the listing says will remain. A 25 mm limit suits light silt. A 35 mm limit suits muddier water. A listing that passes only 5 mm, or that says not to use the pump in dirty water, is a different tool. Maximum litres per hour and maximum head do not happen together. Read the flow as the volume at a modest lift. Many pumps leave the last 20 mm to 30 mm. A claim near 1 mm needs a hard, level base. Outdoor use needs a dry BS 1363 plug and 30 mA RCD protection. The hose is not in the box. The checks are in the [dirty water pump buying guide](/hub/garden-watering/guede-dirty-water-pump/sub/guede-dirty-water-pump-buying-guide).

The best Güde dirty water pumps in detail

FOTING 550 W 17,000 L/h

Rank 1

FOTING 550 W 17,000 L/h

∼£43

Our view

The listing claims 17,000 L/h, 9 m and residual water as low as 1 mm, at about £42.99, rated 4.8 from 25. The display score is 96 because the score is the star share only. That is not a lab result, and 25 reviews are a weak sample. A UK review confirms a UK plug, and notes that the photo looked American. Instructions are called confusing, and connection tails are extra. Particle size is not printed. Some review text in the file describes a 400 W, 8,250 L/h pump, so those sentences may not be this model. Treat 17,000 L/h and 1 mm as listing claims.

Pros

  • Listing claims 17,000 L/h, 9 m and 1 mm residual water
  • Float switches on at about 17.5 cm
  • 4.8 from 25 reviews, the highest star line here
  • A UK review confirms a UK plug

Cons

  • Particle size is not printed
  • Some review text describes a 400 W, 8,250 L/h pump
  • Voltage is not printed, and connection tails are extra
  • 4.8 from 25 is a small sample, not a measured flow

Best for: A buyer who wants the 1 mm residual claim and will check the plug, the particle size and the small review sample.

Less suitable: Anyone who needs a printed particle size, or who treats 4.8 from 25 as stronger evidence than a much larger sample.

Common questions

Does the listing state a particle size?

No. It claims 17,000 L/h, 9 m and residual water as low as 1 mm, with the float switching on at about 17.5 cm. Those flow and residual figures are listing claims, not a measured test.

Why is 4.8 from 25 a weak signal?

The sample is 25 reviews. Some review text in the file describes a 400 W, 8,250 L/h pump, so those sentences may not be this model.

Einhell GC-DP 3325

∼£38

Our view

Across 1,050 amazon.co.uk reviews rated 4.4, one UK review emptied about 800 litres in 25 minutes on 25 mm hose. The listing gives 330 W, 9,500 L/h, a 6 m head and 25 mm solids, with an adjustable float. At about £37.97 it is the best value in this set for a modest job. The display score is 88, the star share only. Included parts are the pump, a 90 degree elbow and a universal adapter. The hose is extra. The technical line says 120 volts, and no other voltage is printed in the file, so check the plate before a UK socket.

Pros

  • 9,500 L/h, 6 m head and 25 mm solids
  • Adjustable float and a folding handle
  • 4.4 from 1,050 amazon.co.uk reviews
  • One UK review emptied about 800 litres in 25 minutes
  • About £37.97 for a modest job

Cons

  • The voltage line says 120 V, and no other voltage is printed
  • Reviews say the last 20 to 30 mm stays
  • Hose is not included
  • 25 mm is light silt, not a muddier 35 mm job

Best for: A cooled hot tub or a light silt drain, if you already own a hose and have checked the voltage plate.

Less suitable: Muddier water that needs 35 mm, or a socket used before the 120 V line is checked.

Common questions

How large a particle does the GC-DP 3325 listing allow?

The item highlight says foreign objects up to 25 mm. That suits light silt. A muddier job in this set is listed at 35 mm.

Does the price include a hose?

No. The included parts are the pump, a 90 degree elbow and a universal adapter.

What voltage does this listing state?

The technical line says 120 volts. No other voltage is printed in the file, so check the plate before a UK 13 A socket.

Einhell GE-DP 7035 LL

Rank 3

Einhell GE-DP 7035 LL

∼£69

Our view

The pump highlight states 700 W, 16,000 L/h, a 7 m head, a 10 m cord and residual water to 1 mm, at about £68.98 and 4.4 from 551 reviews. The display score is 88, the star share only. Particle size is not on the pump lines. The first bullets describe a 1,250 W wet-dry vacuum, which contradicts the pump highlight, the included parts and the reviews. A UK review says the 1 mm setting needs a hard base or the suction blocks, and that the bottom plate is flimsy. Another pool was left with about 2 cm. UK reviews also include a basement, a pond sump and leaking joints. The hose is not listed.

Pros

  • 700 W, 16,000 L/h, 7 m head and a 10 m cord
  • Residual water claimed at 1 mm
  • 4.4 from 551 reviews on 230 V
  • Pump, 90 degree connection and universal connection included

Cons

  • Opening bullets describe a 1,250 W wet-dry vacuum
  • Particle size is not on the pump lines
  • A UK review says the 1 mm setting needs a hard base
  • Another pool was left with about 2 cm, and joints have leaked

Best for: A hard, level floor where the 1 mm residual claim is the point, and you ignore the vacuum-cleaner bullets.

Less suitable: A soft or uneven base, or a job that needs a printed particle size.

Common questions

Why do some bullets describe a vacuum cleaner?

Does 1 mm residual water need a special floor?

A UK review says the 1 mm setting needs a hard base or the suction blocks, and that the bottom plate is flimsy. Another pool was left with about 2 cm.

FOTING 900 W 28,000 L/h

Rank 4

FOTING 900 W 28,000 L/h

∼£57

Our view

The bullets claim 28,000 L/h, 11 m and 38 mm at about £56.99. The star line is 4.4 from 80, and the display score is 88, the star share only. The file has one United Kingdom review. It says the pump did the job and that hoses, pipes and circlips must be ordered separately. Voltage is not printed. Residual water is claimed at about 3.8 cm. There is no pump curve, so treat 28,000 L/h as a listing claim, not a measured duty point. The listed weight is 7.51 kg.

Pros

  • Bullets claim 28,000 L/h, 11 m and 38 mm solids
  • Float switches on at about 17.5 cm
  • 10 m cable and a thermoplastic housing
  • 4.4 from 80 reviews

Cons

  • One United Kingdom review in the file
  • 28,000 L/h has no pump curve and is a listing claim
  • Voltage is not printed
  • Hoses, pipes and circlips are extra

Best for: A buyer who wants the 38 mm and 11 m claims and will budget for hose and fittings.

Less suitable: Anyone who needs a measured flow, a printed voltage, or more than one UK review.

No. It is the listing claim. There is no pump curve in the file, and the head in the bullet is 11 m.

Rank 5

FOTING 900 W stainless 5 mm

∼£63

Our view

Stainless 304 housing at about £62.99, rated 4.4 from 60. The display score is 88, the star share only. The bullet says 13,000 L/h, 9 m and solids up to 5 mm. The title still says dirty and clean water, but 5 mm is not a 35 mm dirty-water intake. A style line says 13,000 GPH, which conflicts with 13,000 L/h. Voltage is not printed. One review could not get useful volume from 3 m below ground through a 5 m hose. Another left about 50 mm in a fish pond. A review reports two pumps in 5 to 6 months. The hose is extra.

Pros

  • 304 stainless steel housing
  • Bullet says 13,000 L/h, 9 m and 5 mm solids
  • Residual water claimed at about 1 cm
  • 4.4 from 60 reviews, 10 m cable

Cons

  • 5 mm solids, so this is not a 35 mm dirty-water pump
  • A style line says 13,000 GPH, which conflicts with 13,000 L/h
  • Voltage is not printed
  • A review reports two pumps in 5 to 6 months

Best for: Cleaner water where a stainless housing matters and solids stay within 5 mm.

Less suitable: Mud, leaves or a 25 mm or 35 mm dirty-water job. The title does not override the 5 mm bullet.

The highest shelf price in the set, about £70.99, for 900 W, 18,000 L/h, a 9 m head, 35 mm solids and a stainless housing, rated 4.3 from 575 reviews. The display score is 86, the star share only. Immersion on the listing is 5 m. Included parts are the pump, a 90 degree angle and a universal connection. A UK review also notes no jubilee clip. The hose is extra. One UK buyer is on a third unit after earlier ones died within months. Listed weight is 7.35 kg. Cable length and residual water are not stated.

Pros

  • 900 W, 18,000 L/h, 9 m head and 35 mm solids
  • Stainless housing and 5 m immersion on the listing
  • Height-adjustable float on 230 V
  • 4.3 from 575 reviews

Cons

  • Hose is not in the box, and a UK review notes no jubilee clip
  • One UK buyer is on a third unit after earlier ones died within months
  • Cable length and residual water are not stated

Best for: A 35 mm job within 9 m and 5 m immersion, when you want a stainless housing and will buy the hose and clip.

Less suitable: A buyer who needs the hose in the box, or who wants residual water printed on the listing.

Our view

The listing states 1,000 W, 17,600 L/h, 11 m, 35 mm and 230 V at about £65.99, rated 4.3 from 308 reviews. The display score is 86, the star share only. UK reviews focus on hot tubs and pools. One review says a hot tub emptied in 15 minutes. Another says a 1,000 litre tub took about 40 minutes and went quite low. Residual water is claimed down to 3.5 cm, with the float cutting power below 3 cm after switching on at about 15.5 cm. One review says the pump is rubbish without naming a part. The hose is extra. Listed weight is 6.42 kg, with a 10 m cable.

Pros

  • 1,000 W, 17,600 L/h, 11 m head and 35 mm on 230 V
  • 4.3 from 308 reviews
  • Float switches on at about 15.5 cm
  • UK hot-tub reviews, including one at about 15 minutes

Cons

  • Residual water is claimed at 3.5 cm, not a 1 mm floor
  • The hose is extra
  • One review says the pump is rubbish without naming a part
  • Higher price than the 35 mm listings near £40 to £50

Best for: A hot tub or pool within an 11 m head, when you want 35 mm and a few hundred reviews.

Less suitable: A floor you want taken down to about 1 mm, or a buyer who has not budgeted for the hose.

Our view

The amazon.co.uk file prices the Güde GS 4003 P at about £34.65 and states 8,000 L/h, 5.5 m, 25 mm, 230 V, a 10 m cable and 2.3 kg. The display score is 86, the star share of 4.3 from 271. The float is not in the specification bullets. The maker’s English page mentions a float and about 25 mm left. Written reviews are labelled Germany, including shock reports, and are not UK opinion. The maker’s PDF prints 400 W, 4 m immersion, 3.25 kg and a female thread. Those are not the amazon.co.uk lines, which print 0.53 hp, 7 m immersion, 2.3 kg and a male 1 1/4 inch thread. The manual forbids circulation, drinking water, pressure boosting and a permanent cellar overflow. No hose is listed.

Pros

  • 8,000 L/h, 5.5 m head and 25 mm on 230 V
  • 10 m cable, plastic housing, 2.3 kg on the listing
  • Lowest shelf price in this set, about £34.65
  • Listing immersion 7 m and a 35 °C line

Cons

  • Float is not in the amazon.co.uk specification bullets
  • Written reviews are labelled Germany, including shock reports
  • No hose; the listing prints a male 1 1/4 inch thread
  • 5.5 m head is the shortest in this set

Best for: A short 25 mm drain within 5.5 m, if you accept that the written reviews are not UK opinion.

Less suitable: A muddy 35 mm job, a lift above 5.5 m, circulation duty, or anyone quoting the Germany-labelled reviews as British buyers.

Common questions

What flow and head does the GS 4003 P listing state?

The amazon.co.uk file states 8,000 litres per hour and a maximum delivery height of 5.5 m, with a 25 mm grain size. The listing prints 0.53 hp, not a watt figure.

Does this file include United Kingdom reviews?

The star line is 4.3 from 271. Every written review in the file is labelled Reviewed in Germany, so those comments are not UK opinion. Shock reports in that file are not a UK rate.

Is a hose included at about £34.65?

No hose is listed. The connection printed on the listing is a male 1 1/4 inch thread. The maker’s PDF prints a female thread, so check the pump you receive.

∼£40

Our view

At about £39.99 and 4.3 from 99 reviews, UK reviews empty hot tubs. The display score is 86, the star share only. The same file limits solids to 5 mm and says not to use the pump in dirty water, even though the title says dirty and clean water. Head is 8 m on the specification line and 7 m in the bullet. Residual water is claimed at 7 mm. The listed weight is 4.29 kg, on 230 V, with a 10 m cable. UK reviews say a standard garden hose does not fit and a flat hose had to be ordered. The adapter list is 33 mm, G1, G1 1/4 and 26 mm.

Pros

  • 8,250 L/h on 230 V with a stainless housing
  • Residual water claimed at 7 mm
  • 4.3 from 99 reviews
  • 10 m cable and a multi-hose adapter

Cons

  • A bullet says not to use the pump in dirty water
  • Solids limited to 5 mm
  • Head is 8 m on the spec line and 7 m in the bullet
  • UK reviews say a standard garden hose does not fit

Best for: A cooled tub of fairly clean water, if you order a hose that matches the adapter.

Less suitable: Dirty water. The bullet says not to use this pump there, and the particle limit is 5 mm.

Top pick on review volume for a stated 35 mm dirty-water job: 4.2 from 10,114 reviews, 780 W, 15,700 L/h and an 8 m head at about £50.50. The display score is 84, the star share only, not a lab test. A UK review emptied a 2,000 litre pond in about 12 minutes, and one review mentions stones up to about 30 mm. The listing maximum is 8 m. A Devon reviewer could not raise water 10 m in one stage. Failures include a float that died after about a month. The cable rewind length is not stated, and the hose is not in the box.

Pros

  • 15,700 L/h, 8 m head and 35 mm solids on 230 V
  • 4.2 from 10,114 amazon.co.uk reviews
  • A UK review emptied a 2,000 litre pond in about 12 minutes
  • Float and carry handle are on the listing
  • 780 W, plastic housing, about 5 kg

Cons

  • Will not lift 10 m in one stage; the listed maximum is 8 m
  • A float that died after about a month is in the sample
  • Hose is not listed
  • Residual water is not stated

Best for: A one-off cellar or pond within the 8 m head, when you want the largest review sample for a 35 mm job.

Less suitable: A single lift of 10 m, or anyone who needs a stated residual-water figure.

With 4.2 from 2,607 reviews, this 900 W listing states 14,000 L/h, 8.5 m, 35 mm and 230 V at about £46.99. The display score is 84, the star share only, so the large review count does not raise the score above a higher star line. UK uses include hot tubs and pools. One review drained about 9,000 litres from a 12 ft pool, 1 m deep, in just over an hour. One review says a 5 m hose over a track did not give enough pressure to clear field flooding. One buyer reports a consumer-unit trip on an earlier unit. Residual water is claimed at about 3 cm. The hose is extra. Listed weight is 5.76 kg, with a 10 m cable.

Pros

  • 14,000 L/h, 8.5 m head and 35 mm on 230 V
  • 4.2 from 2,607 reviews
  • UK uses include hot tubs and pools
  • One review drained about 9,000 litres in just over an hour

Cons

  • A 5 m hose over a track lacked pressure for field flooding
  • One buyer reports a consumer-unit trip on an earlier unit
  • Residual water is claimed at about 3 cm
  • The hose is extra

Best for: Hot tubs and pools within 8.5 m, when you want 35 mm and a review count in the thousands.

Less suitable: A raised discharge that needs sprinkler pressure, or a floor you want taken below the claimed 3 cm.

Common questions

What does a UK review say about volume?

One review drained about 9,000 litres from a 12 ft pool, 1 m deep, in just over an hour. That is a review report, not a pump curve.

Does flow hold over a raised hose?

One review says a 5 m hose over a track did not give enough pressure to clear field flooding. Maximum flow and maximum head do not happen together.

Our view

UK reviews at 4.2 from 62 include a 2,500 litre rain tank, a pond and a hot tub emptied in 20 minutes. The display score is 84, the star share only. The listing claims 16,000 L/h, 8 m and 35 mm at about £39.99, with the float on at about 17.5 cm and residual water claimed at about 3.8 cm. Two reviews report failure within months. The horsepower line says 1.5 horsepower, which conflicts with the 550 W bullet. Voltage is not printed. The hose is extra. Listed weight is 5.8 kg, with a 10 m cable.

Pros

  • 16,000 L/h, 8 m head and 35 mm solids
  • Float switches on at about 17.5 cm, with a 10 m cord
  • UK reviews include a rain tank, a pond and a hot tub
  • About £39.99

Cons

  • Two reviews report failure within months
  • A 1.5 hp line conflicts with the 550 W bullet
  • Voltage is not printed
  • The hose is extra, and residual water is a claim of about 3.8 cm

Best for: A 35 mm drain near this price, if you accept a 62-review sample and a power-line conflict.

Less suitable: Anyone who needs a printed voltage, or who wants the larger 10,114-review sample on the GC-DP 7835.

Common questions

What solids does this FOTING listing claim?

The bullet says up to 3.5 cm, which is 35 mm, and residual water down to about 3.8 cm. The residual figure is a listing claim.

Is the voltage printed?

No voltage is printed. The horsepower line says 1.5 horsepower, which conflicts with the 550 W bullet.

How we compared

There is no separate scoring file for this comparison. Each listing score is the amazon.co.uk star share only, so 4.2 becomes 84 and 4.8 becomes 96. Review count is not inside that number. The top pick and the best value are the display awards: review volume for a stated 35 mm job, and a lower price for a modest 25 mm job. They are not the highest star-share score. The weights below follow the buying-criteria order in the digest and sum to 100. This is not a lab test and not a measured flow.

1

Particle size

25%

25 mm suits light silt. 35 mm suits muddier water. A 5 mm listing is a different tool, including one bullet that says not to use the pump in dirty water. Stainless steel is not a 35 mm intake.

2

Head and flow

25%

Vertical lift comes before the litres-per-hour line. Maximum flow and maximum head do not happen together. A flow figure with no pump curve stays a listing claim.

3

Residual water

20%

Ordinary reviews here leave about the last 20 mm to 30 mm. A claim near 1 mm needs a hard, level base. A float cut-in near 15 cm to 18 cm is a different figure.

4

Plug and voltage

20%

All twelve listings are mains. Outdoor use needs a dry BS 1363 plug and 30 mA RCD protection. A 120 V line means check the plate. No delivery hose is in the box.

5

Duty

10%

One manual prints 35 °C and forbids circulation, drinking water, pressure boosting and a permanent cellar overflow. Do not copy 35 °C onto a listing that omits it. Stars are not a lab result.

Güde dirty water pump buying guide

Choose by particle size, then head, then how much water is left, then the plug. A high litres-per-hour line is the volume at a modest lift, not at the maximum head. Prices below are the amazon.co.uk shelf prices in the listing files.

What to check on a dirty water pump

A dirty water pump in this search is a mains submersible for a short drain. It is not a sprinkler and not a sewage pump. Particle size is the first split. A 25 mm limit, as on the GS 4003 P and the GC-DP 3325, suits light silt. A 35 mm limit, as on the GC-DP 7835, the GC-DP 9035 N and several FOTING bullets, suits muddier water. Two FOTING listings pass only 5 mm. One bullet says not to use that pump in dirty water, even though the title says dirty and clean water.

Best for

  • A cooled hot tub on a mains socket, if you already own a hose and can accept a few centimetres left
  • A one-off muddy cellar within the listed head, with 30 mA RCD protection and a UK 13 A plug

Not ideal for

  • A sprinkler, drinking water, circulation duty, or water above a printed temperature limit
  • A permanent cellar overflow, a flood every winter, or electrics that have already been under water

Mistakes to avoid

  1. 1

    Reading only litres per hour

    Maximum flow and maximum head do not happen together. The GS 4003 P lists 5.5 m. The GC-DP 7835 lists 8 m, and a Devon review could not lift 10 m in one stage. The 28,000 L/h line has no pump curve beside it.

  2. 2

    Treating a 5 mm listing as a dirty-water pump

    Two FOTING listings pass only 5 mm. One bullet says not to use the pump in dirty water. Stainless steel does not turn a 5 mm intake into a 35 mm pump. A standard garden hose did not fit one of those listings.

  3. 3

    Quoting Germany-labelled reviews as British buyers

    The GS 4003 P star line is 4.3 from 271, and the written reviews are labelled Germany, including shock reports. That is not a UK rate. A shock means stop and call a registered electrician. The hose is not in any box here.

What to weigh up

Particle size, head and residual water

High

Match 25 mm or 35 mm to the debris, then measure the lift before you trust litres per hour. A 5 mm bullet is a different tool. Ordinary reviews here leave about the last 20 mm to 30 mm. A 1 mm claim needs a hard, level base. A float cut-in near 15 cm to 18 cm is not the water left at the end. Maximum flow and maximum head do not happen together, and a figure with no pump curve stays a listing claim.

Plug, voltage and duty

High

A mains pump needs a BS 1363 plug and 30 mA RCD protection outdoors. The GC-DP 3325 file prints 120 V and no other voltage, so check the plate. The hose is extra on every listing. One manual prints 35 °C and forbids circulation, drinking water, pressure boosting and a permanent overflow. Do not copy that temperature onto a listing that omits it. Review count is not a lab test: 10,114 reviews are not the same evidence as 25.

Which option suits you?

Three typical situations, each with a recommendation from this comparison.

Cooled hot tub

You have a socket, the water has cooled, and a few centimetres left behind is acceptable. The Einhell GC-DP 3325 lists 330 W, 9,500 L/h and a 6 m head at about £37.97, with 4.4 from 1,050 reviews. One UK review emptied about 800 litres in 25 minutes on 25 mm hose. The hose is extra, and the listing prints 120 V, so check the plate.

Muddy cellar

A one-off muddy cellar needs 35 mm solids, a float, an RCD and a legal discharge. The Einhell GC-DP 7835 lists 780 W, 15,700 L/h and an 8 m head at about £50.50, with 4.2 from 10,114 reviews. It will not lift 10 m in one stage. A float that died after about a month is in the sample.

Short pond drain

A pond clean-out is a short drain, then the pump comes out. The Güde GS 4003 P lists 8,000 L/h, a 5.5 m head and 25 mm at about £34.65. The manual forbids circulation duty. Written reviews are labelled Germany, so they are not UK opinion. Skip it if the lift is more than 5.5 m.

Common questions about Güde dirty water pumps

What is a dirty water pump used for?
A dirty water pump on these amazon.co.uk listings is a mains submersible for a short drain of sandy or muddy water, such as a cooled hot tub, a pond or a cellar. It is not a sprinkler and not a sewage pump. A 25 mm limit suits light silt. A 35 mm limit suits muddier water. Two listings here pass only 5 mm, and one says not to use the pump in dirty water. Maximum litres per hour and maximum head do not happen together.
Which listing is the top pick in this set?
The top pick in this set is the Einhell GC-DP 7835 at about £50.50. The listing states 780 W, 15,700 L/h, an 8 m head and 35 mm solids on 230 V. Amazon.co.uk shows 4.2 from 10,114 reviews. The display score is 84, the star share only, not a lab test. A UK review emptied a 2,000 litre pond in about 12 minutes. The listed maximum is 8 m. A Devon reviewer could not raise water 10 m in one stage.
Which listing is the best value?
The best value in this set is the Einhell GC-DP 3325 at about £37.97, with 4.4 from 1,050 amazon.co.uk reviews and a display score of 88. It states 330 W, 9,500 L/h, a 6 m head and solids to 25 mm. One UK review emptied about 800 litres in 25 minutes on 25 mm hose. Reviews say the last 20 to 30 mm stays. The hose is extra. The file prints 120 V and no other voltage, so check the plate.
Does an outdoor dirty water pump need an RCD?
Socket-outlets up to 32 A for outdoor mobile equipment need 30 mA RCD protection under BS 7671 regulation 411.3.3, as Electrical Safety First explains it. Uncoil outdoor leads and unplug the pump before you clean it. Mains pumps fall under the Electrical Equipment (Safety) Regulations 2016. CE marking remains recognised in Great Britain. Northern Ireland stays on CE. A shock means stop and call a registered electrician. Two written reviews of the Güde listing describe shocks, but those reviews are labelled Germany, so they are not a UK rate.
Can one of these pumps feed a sprinkler?
These pumps are for drainage, not for a sprinkler or for pressure boosting. Maximum flow and maximum head do not happen together, and a high litres-per-hour line is not a jet. The Güde manual forbids pressure boosting, circulation and drinking water. A UK review of one 900 W listing said a 5 m hose over a raised track did not give enough pressure to clear field flooding. The delivery hose is extra on every listing here. A garden pump is the tool when the job is a hose jet.
How much water will be left?
Residual water and the float switch are different figures. UK reviews of the GC-DP 3325 say the last 20 to 30 mm stays. The Güde English page says about 25 mm left, while the amazon.co.uk bullets for that listing do not state it. The GE-DP 7035 LL claims about 1 mm, and a UK review says that needs a hard base or the suction blocks. Several floats switch on at about 15 cm to 18 cm, which is the depth needed to start, not the depth left at the end.
Can you pump a hot tub immediately?
Only if the water has cooled to the temperature the manual allows. The Güde manual prints 35 °C and forbids circulation, drinking water, pressure boosting and a permanent cellar overflow. Do not copy 35 °C onto a listing that omits it. A cooled tub needs a modest mains pump and a separate hose. The GC-DP 3325 is the best value here for that job, and its file prints 120 V, so check the plate. The pump comes out when the drain is done.
When should you stop and call a professional?
Call a professional for soaked electrics, a shock, a cellar that floods every winter, water about a metre deep, or a discharge that may need consent. GOV.UK says start hard pumping only when outside water is lower, do not flood someone else, and about a metre of water means a structural engineer. A permit may be required. Einhell listings that are not in this twelve, including cordless bodies, are in the Einhell dirty water pump comparison.

Our verdict

In this set the top pick is the Einhell GC-DP 7835: 780 W, 15,700 L/h, an 8 m head and 35 mm solids at about £50.50, with 4.2 from 10,114 amazon.co.uk reviews. The display score is 84, the star share only, not a lab test. The best value is the Einhell GC-DP 3325 at about £37.97, score 88, with 4.4 from 1,050 reviews, 9,500 L/h and a 6 m head. The hose is not in that box, and the listing prints 120 V, so check the plate. The only Güde listing, the GS 4003 P, is about £34.65 with 8,000 L/h and 5.5 m. Its written reviews are labelled Germany, so they are not UK opinion.
