Trotec dirty water pump or clean water?

Updated: October 2026

A flooded cellar, a silty pond and a rain butt can look like the same drainage job until debris reaches the inlet. The Trotec dirty water pump in this comparison is the TWP 11000 ES. The TWP 4006 E is titled for clean water, even though its bullets also mention flooding. The [Trotec pump comparison](/hub/cooling/trotec-pump) records both amazon.co.uk listings as they appeared. This page shows which title fits which water, and why a larger litres-per-hour number cannot replace that decision. The Products Compared editorial team compared the listings in October 2026 and did not run a laboratory test.

Two titles, two duties

The TWP 11000 ES was about £104.43 with 4.2 from 257 reviews. Its title says waste water, 1,100 W and up to 20,000 l/h, and it does not state what solid size can pass. The TWP 4006 E was about £49.50 with 4.3 from 528 reviews. Its clean-water title states 7,300 l/h. Bullets mention flooding, but clear rainwater is not silt, sewage or building debris. Choose by what is in the water. To separate a TWP from a surface, pressure or borehole pump, start with the Trotec pump buying guide.

Why 20,000 l/h is not the dirty-water proof

The TWP 11000 ES has a much higher stated maximum flow, but flow does not prove debris tolerance. The Amazon evidence is its waste-water title. The particle allowance is missing. A high-flow pump can still be vulnerable to solids. The TWP 4006 E is a lighter-duty choice with a float, non-return valve and flat suction. At about half the price, it is the best-value pick for clean water. Choose the dearer model only when its waste-water duty and a verified solids allowance match. The TGP 1005 E stays on dry ground. Its 1 mm pre-filter is not a waste-water rating.

What the amazon.co.uk pages print

The TWP 11000 ES Amazon page prints no solids size. Bullets state a 7 m immersion and pumping from a 50 mm water level to a maximum suction height of 40 mm. The lifting-height field is 354.33 inches. Keep that field as printed. The float line says without switch with float switch. A 10 m rope is named. No hose, cable length, thermal protection or IP rating is recorded. The TWP 4006 E highlight states flat suction to 5 mm. That is residual water, not a 5 mm particle claim. Its lifting field is 275.59 inches and the immersion highlight says 23 ft. The page names a float, non-return valve, 10 m rope and angle adapter, and no hose. The model field says TDP DSA, while the title and part number 4610000004 identify the TWP 4006 E. Check the delivered model.

Shop and manual figures stay labelled

The UK TROTEC shop page states particles up to 25 mm and a 9 m head for the TWP 11000 ES. Neither figure is on the stored Amazon listing. If you rely on 25 mm, name that source and confirm the supplied model. For the TWP 4006 E, the UK shop and manual state particles up to 5 mm, and the manual separately gives 5 mm residual water. Amazon only highlights flat suction. Shop prices may exclude VAT and do not replace the Amazon figures used here.

Rope, float and when to stop

Both bullet lists name a 10 m rope. Attach it to the designated lifting point, never the cable or hose. Neither listing names a hose or a BS 1363 plug. Keep the float free so it can stop the pump before dry running. Resolve the TWP 11000 ES switch wording before you rely on automatic control. Stop if debris exceeds the confirmed allowance, or if the water may contain sewage or chemicals. Do not enter flood water where electricity may be present. For the first run, follow the Trotec pump setup guide. A qualifying amazon.co.uk purchase may earn us a commission at no extra cost to you.

Common questions

Which title should you open for dirty water?
Open the TWP 11000 ES listing because its title explicitly says waste water. Its Amazon page states up to 20,000 l/h but no solids size. Confirm the particle allowance for the exact delivered model before using it with debris. It was about £104.43 with 4.2 from 257 reviews.
Why does the clean-water pump mention flooding?
Flood water is not always dirty. Rainwater in a relatively clean basement or drainage well may suit a clean-water pump, while silt, leaves, sewage or rubble may not. The TWP 4006 E title still says clean water, and its Amazon page gives no particle allowance.
Does the TWP 11000 ES Amazon page state 25 mm solids?
No. The stored amazon.co.uk page gives no solids size. The particles-up-to-25-mm line comes from the UK TROTEC shop page for that model. Keep the source clear and verify it against the supplied manual.
Is flat suction to 5 mm a particle rating?
No. Flat suction describes the residual water level the pump may reach in the relevant operating arrangement. Particle size describes what can pass through the pump. The TWP 4006 E manual gives both as separate 5 mm entries, but its Amazon highlight only states flat suction.
Do either listings include a hose?
No hose is named in either stored listing. Both bullet lists name a 10 m nylon rope, and the TWP 4006 E names an angle adapter. Check hose diameter, connector and clamp requirements in the correct manual before purchase.
What should you do with the TWP 11000 ES float wording?
Treat it as unresolved. The listing says both without switch and with float switch. Inspect the delivered product, read the exact model manual and test the float safely before relying on automatic unattended pumping.
When should a professional handle the flood?
Get professional help when water may contact live electrics, contains sewage or chemicals, is entering faster than you can control, or has already spread through an occupied building. Pump selection alone does not make the area safe.
