The best Hose levels, compared.
Top pick: kwb 20 m hose (0647-20) Best value: as-Schwabe 10 m PVC hose – Lowest price in this set at about £10.56 for a titled 10 m PVC hose, with no sight tubes on the listing. Updated October 2026.
A hose level, also called a water level, is a clear tube of water. When both ends are open to the same air, the two free surfaces sit at one height. You use it to carry a mark around a corner, through a doorway, or along a fascia, where a laser has no line of sight. The hose goes the long way around, with slack, because a taut hose spills water or sucks air. Judge reach, a readable scale, and caps you can take off. Its title says 10 m, and an item-length field says 21 cm. Length, tubes, caps and bore are set out in the [hose level buying guide](/hub/measuring-and-marking-tools/hose-level/sub/hose-level-buying-guide). Many marks in one open room are usually faster with a laser. A whole plot needs an optical or rotary level. A nozzle, a reel, a washer tube, or a pipe aligner is not this category.

Personal buying guide
Question 1 of 2
What do you need to read?
The kwb 0647-20 is a 20 m transparent plastic hose at £18.99, with a bullet diameter of 8 mm described as the inner diameter. The star line is 5.0 from five reviews, and the listing has no review text, so there is nothing to quote about bubbles, caps, or accuracy. Sight tubes, a scale, caps, and a case are not named. Origin is given as France and the listed weight is 940 g. The bullets mention foundation work, grading, and other levelling, and they do not answer the gardening question in the spec block. Five stars on five silent reviews are not a reason to place it above a hose with hundreds of written comments. It is a long clear hose on the listing, and the missing review text is the limit.
Pros
Cons
Best for: You already want a plain 20 m hose and will judge the column yourself after it arrives.
Less suitable: You are sorting by stars, or you need a scale and written UK reviews.
Specifications
Common questions
What does the kwb listing include?
A 20 m transparent plastic hose, model 0647-20. The bullet gives a diameter of 8 mm and calls it the inner diameter. Sight tubes, a scale, caps, and a case are not named.
Is it described as suitable for gardening?
The listing asks that question. The bullets name foundation work, grading, and other levelling. They do not answer the gardening question in the spec block.
What do buyers say about it?
The star line is 5.0 from 5 reviews. The listing has no review text, so there is no praise or complaint to quote.
The as-Schwabe 15 m listing is a PVC hose at £13.11, with an 8 mm outside diameter, a 1.5 mm wall, and a listed weight of 840 g. The page states that it is made in Romania. It scores 4.4 from 515, and those stars plus the same three UK review texts also sit on the 10 m ASIN, so treat them as one parent block. The bullets do not name sight tubes, a scale, or caps. One of those shared UK reviews used the hose on a fascia to mark level and then work out a gutter fall, which is a plain-hose job. The rank on the listing is 305 in Spirit Levels. There is no case in the spec. Choose it when 15 m of hose is the requirement and you will mark the waterline by eye.
Pros
Cons
Best for: Transferring one height along about 15 m when you do not need to read a fall on a scale.
Less suitable: You need millimetre marks, or a review count that belongs only to this ASIN.
Specifications
Common questions
Is this a hose only, or a kit with tubes?
The title is a PVC hose water level, 8 mm by 1.5 mm, 15 m. The bullets do not mention sight tubes, a scale, or caps.
Can it be used outdoors?
The listing asks that and does not answer it in the spec block. One UK review, shared with the 10 m ASIN, used it on a fascia to mark level and then work out a gutter fall.
Why is the star line the same as the 10 m hose?
This file and B008YSFOCO both show 4.4 from 515, and the same three UK review texts. Treat that as one parent block.
The as-Schwabe 10 m hose is the lowest price in this set at £10.56, with an 8 mm outside diameter, a 1.5 mm wall, and a listed maximum pressure of 4 bar. The title and a bullet say 10 metres, while the item-length field says 21 centimetres and the dimensions field says 21 cm by 21 cm, so both figures are on the page. The 4.4 from 515 is the same parent block as the 15 m ASIN, including the fascia review, and one UK text says the hose is not for gasoline. Included components are the hose itself, listed at 550 g, and the page states Romania as the origin. Sight tubes and a scale are not named. The 4 bar line is a hose rating in the spec, and the listing does not tell you to pressurise a filled level. It is the best value when you only need the same height and you can live with the length-field clash.
Pros
Cons
Best for: A short level transfer where a plain hose is enough and about £10.56 is the point of the purchase.
Less suitable: You need a printed scale, or you will not buy until the 10 m title and the 21 cm field agree.
Specifications
Common questions
How long is this hose?
The title and the bullet say 10 metres. The item-length field says 21 centimetres, and the dimensions field says 21 cm by 21 cm. Both figures are on the listing.
Does the listing include sight tubes?
No. The included-components line is Hose spirit level 10 m. There is no scale and no tube size.
What does the 4 bar figure mean here?
The listing prints a maximum pressure of 4 bar. That is the hose rating in the spec block. The file does not say to pressurise a filled water level. One UK review says not for gasoline.
The Cellfast 22-101 lists 20 m of hose, two 21 cm plexiglas tubes, and a 0–10 cm millimetre scale at £14.01. Across 508 amazon.co.uk reviews it sits at 4.2, and the Tube Levels rank on the listing is 13. The bore is stated as 8 mm inside and 10 mm outside with a 1 mm wall, which is the only fully printed tube-and-bore set in this comparison. One UK review needed pliers on the end caps and switched to wine corks, so a cap you can open by hand is not guaranteed. The included-components field says No while the bullets name the fittings and tubes, so check the box against the bullets when it arrives. The listed weight is 780 g. It is the top pick here because the scale, the tubes, and the bore are actually printed, with the cap complaint as the practical limit if you work alone.
Pros
Cons
Best for: A home mark where you want a printed 0–10 cm scale on a 20 m hose and you can free the caps.
Less suitable: You need caps that open by hand every time, or a 25 m run around a large garden.
Specifications
Common questions
Does the Cellfast 20 m kit include graduated tubes?
The bullets say two plastic fittings and plexiglas measuring tubes, with a 0–10 cm scale in millimetres. The tubes are 21 cm long and 12 mm across. The included-components field says No.
What is the hose diameter?
The listing states 10 mm outside, 8 mm inside, and a 1 mm wall. The weight is 780 g and the hose length is 20 m.
Does it come with a case?
The listing asks that question and does not name a case. One UK review says the end caps need pliers and that wine corks were easier.
This Cellfast 15 m set is £13.99 and carries the largest review count in the set, at 4.1 from 889. The bullets describe an unbreakable cylinder with a millimetre scale, though they do not state the scale range, the tube size, or the hose bore. UK reviews often say the hose is narrow and that bubbles are hard to clear, and one puts the error at about 20 mm until the air is out. Several buyers say a siphon fill works once the column is clear. The printed scale rubbed off in more than one review, and the caps are described as very tight or liable to pop off. One buyer found the cylinders and stoppers missing. It is a widely reviewed 15 m kit with a scale named in the bullets, and the bubble and cap complaints are why it is not the top pick.
Pros
Cons
Best for: A 15 m reach where you will siphon-fill the hose and can accept a scale whose range is not printed.
Less suitable: You need a stated bore, or a scale that buyers say stays readable.
Specifications
Common questions
Does this 15 m Cellfast set include a scale?
The bullets say an unbreakable cylinder with a clear millimetre scale. They do not state the scale range, the tube size, or the hose bore.
Does it come with a case?
The listing asks and does not name a case. One UK review found the end tubes loose in the bag with the hose. Another says the cylinders and stoppers were missing.
What do the UK reviews say about filling it?
Several say the hose is narrow and that bubbles are hard to clear. One says the error reached about 20 mm. Others say a siphon fill works once the air is out. The printed scale rubbed off in more than one review.
The Cellfast 25 m set is the longest hose in this comparison at £17.12, with 4.0 from 64 reviews. The bullets name an unbreakable cylinder and a millimetre scale, and they do not state the scale range. The outside-diameter field says 1 centimetre, and the wall field says 1 with no unit, so the bore is not fully specified. Four UK reviews mention stiff end caps. One says the top pipes leak and a cap cannot be closed, and one buyer uses a thumb instead of the cap. Country of origin is Poland, the listed weight is 920 g, and the rank sits under Garden Hoses. The listing also prints a 4 bar maximum as a hose rating. Reach is the reason to open this page, provided you can work with stiff caps and a smaller review sample.
Pros
Cons
Best for: A long garden or a path around a house where a 20 m hose would finish tight.
Less suitable: You want caps that turn by hand, a Tube Levels rank, or a fully stated bore.
Specifications
Common questions
How long is this Cellfast set?
The item length is 25 metres. The bullets describe an unbreakable cylinder with a millimetre scale and do not state the scale range.
What diameter does the listing give?
The outside-diameter field says 1 centimetre. The wall field says 1 and gives no unit. An inside diameter is not stated.
Does it come with a case?
The listing asks and does not name a case. Four UK reviews mention stiff end caps. One says the top pipes leak and a cap cannot be closed. One uses a thumb instead of the cap.
The Faithfull FAIWL10HM is listed at £21.99 for a titled 10 m / 33 ft water level, at 3.7 from 67 amazon.co.uk reviews. Item weight is 472 g, and a bullet says 0.48 kg. Bore, wall, and a scale are not on this amazon.co.uk listing. Five UK texts are on the listing: one says only good, and the others say the hose falls off a conical connector and loses water, that a tap handle broke, and that the item did not match the picture. There is no case named. At the top of this set’s prices, the connector complaints are the reason to skip it unless you already want this model and will check the joints before the first fill.
Pros
Cons
Best for: A buyer who specifically wants the Faithfull name and will inspect the connector before the first fill.
Less suitable: You want the lowest price, a millimetre scale printed on amazon.co.uk, or a hose that reviewers say stays on the fitting.
Specifications

Does it come with a case?
The listing asks and does not name a case. Included components are the water level itself.
What do the UK reviews report?
Five UK texts are on the listing. One says only good. Others say the hose falls off a conical connector and loses water, that a tap handle broke, and that the item did not match the picture.
Shelf prices, stars and review counts are the seven amazon.co.uk listings in this set, captured on 20 October 2026. There was no lab test. Scores follow the display reading of reach, printed tubes and scale, caps, bore, and what the listing actually states. Weights sum to 100.
Reach with slack
25%The hose goes the long way around, not the straight line. A taut hose spills water or sucks air. Lengths in this set are 10 m, 15 m, 20 m and 25 m.
Sight tubes and scale
25%A gutter fall needs a scale you can still read, then you subtract the fall. A stated range, such as 0–10 cm, scores above a bullet that only says millimetre.
Caps you can remove
20%Both ends stay open while you read. UK reviews that need pliers, a cork, or a thumb score lower than a listing that is silent on caps.
Bore you can clear
15%A stated inside diameter you can keep round, and clear of bubbles, scores above a missing bore. A review that puts the error at about 20 mm until the air is out is a deduction.
What the listing states
15%Printed tube size, wall and origin score above a bullet that the spec block does not repeat. Shared star lines and five silent reviews are not treated as a second sample or as written comments.
Seven hose levels on amazon.co.uk, captured on 20 October 2026, run from about £10.56 to about £21.99. The useful differences are reach with slack, a readable scale, caps that come off, and a bore you can clear of bubbles. The Cellfast 20 m kit is the top pick because those tube and bore figures are printed. The as-Schwabe 10 m hose is best value if the same height is enough and you can live with a 10 m title beside a 21 cm item-length field.
A hose level, or water level, is a clear tube of water. When both ends are open to the same air, the two free surfaces sit at one height. You carry that height around a corner, through a doorway, or along a fascia, where a laser has no line of sight. Many marks in one open room are usually faster with a laser. Whether a hose or a laser fits the job is set out in [hose level vs laser](/hub/measuring-and-marking-tools/hose-level/sub/hose-level-vs-laser).
Both ends stay open to the same air while you read. A cap left on, or a cap so tight you need pliers, stops the column. UK reviews on the Cellfast kits mention pliers, corks, stiff caps, caps that pop off, and a thumb used instead of the cap.
Read the same side of the meniscus at both ends. A bubble or a kink left in the hose moves the surfaces. On the 15 m Cellfast, UK reviews say bubbles stick, and one puts the error at about 20 mm until the air is out.
A 25 m hose is for a long way around, with slack. It is the wrong length for one room. A seller line that the hose is more precise than a laser is not a test of these ASINs. Call a professional for a regulated drain, for setting out a building, or when a damp-proof course is missing or bridged.
Reach is the first cut, and it is the long way around, not the straight line between the two marks. A taut hose spills water or sucks air, so you buy slack as well as distance. In this set the titled lengths are 10 m on the as-Schwabe hose at about £10.56 and on the Faithfull FAIWL10HM at about £21.99, 15 m on the Cellfast set at about £13.99 and the as-Schwabe hose at about £13.11, 20 m on the Cellfast 22-101 at about £14.01 and the kwb 0647-20 at about £18.99, and 25 m on the Cellfast set at…
A gutter fall needs a scale, then you subtract the fall. The Cellfast 20 m bullets state a 0–10 cm millimetre scale and plexiglas tubes 21 cm by 12 mm. The Cellfast 15 m and 25 m bullets name a millimetre scale and do not state the range. On the 15 m set, UK reviews say the printed scale rubbed off. as-Schwabe and kwb do not name tubes or a scale, so you mark the waterline by eye. Both ends stay open while you read.
Three typical situations, each with a recommendation from this comparison.
You want one height carried around a corner or through a doorway, and you want the scale range printed. The Cellfast 20 m kit, model 22-101, is about £14.01, with a 0–10 cm millimetre scale, 21 cm tubes, and 8 mm inside. It shows 4.2 from 508 reviews. One UK review needed pliers and used corks.
A 20 m hose would finish tight, so you want the longest reach in this set. The Cellfast 25 m set is about £17.12, with a millimetre scale named in the bullets and 4.0 from 64 reviews. The scale range is not stated, and UK reviews describe stiff caps.
You do not need to read a fall. The as-Schwabe 10 m PVC hose is about £10.56, with 8 mm outside and a 1.5 mm wall. The title says 10 m and the item-length field says 21 cm. Sight tubes are not listed. The 4.4 from 515 is shared with the 15 m as-Schwabe hose.
The top pick is the Cellfast 20 m kit, model 22-101, at about £14.01. It is the only listing here that prints a 0–10 cm scale, 21 cm plexiglas tubes, and an 8 mm inside diameter, with 4.2 from 508 amazon.co.uk reviews. One UK review needed pliers on the caps. Best value is the as-Schwabe 10 m PVC hose at about £10.56, if the same height is enough and you can live with a 10 m title beside a 21 cm item-length field. A 25 m Cellfast set is for a long run, not for one room. None of these scores is a lab result or a UK-wide ranking.
as-Schwabe 10 m PVC hose
Lowest price in this set at about £10.56 for a titled 10 m PVC hose, with no sight tubes on the listing.
