Wirquin 90 mm Slim Shower Waste Membrane Trap 40 mm Height

The AAV (air admittance valve) in my en-suite was replaced done time ago with waterless traps to reduce wasted space but since one of them broke (someone was too vigorous with a plunger!) I've had nothing but issues as the replacement valve was built and reduced the drop angle and was too restrictive making it drain too slowly making the shower unusable. This is really (and I mean really!) slim which has increased the drop thus improving the flow and there is practically no pressure reduction even on full power so my shower drains instantly with no buildup. The valve is really easy to remove, clean and replace and provides a completely airtight seal so no foul odours. This has saved me ripping it half the bathroom to fit an AAV and loss smarter/performs better so I'm well pleased!

Easy part to fit Good quality part

Very good product. Only wanted the connection plate and chrome top to replace the inferior previous model. Fitted straight on.

I use these for all the shower trays I fit that have 90mm wastes. Great flow, easy to clean out and never had an issue. Wong sized for solve t weld pipe too give peace of mind that it won’t leak.

This part gets you out of trouble when you only has a small gap

Needed a waste pipe that would setup drain smells coming back in to the bathroom. Product itself was easy to install (though the location under an in situ shower tray made that more difficult) and the valve is easy to remove and clean. Excellent product for when there is no room for a full u-bend.

A life saver when you find that the waste is positioned over or near a joist as these wastes have a very low profile

After having a loft extension our builder fitted a very noisy waste pump for the shower. He told us he couldn't get the drop needed without it. After suffering for a year i decided to cut a hole in the ceiling and try this shallow trap. I am very happy to say this gave me more than enough drop and the shower drains fine with absolutely no pooling. The only negative is that because it is so shallow, it only just clears the shower tray and I have had to cut into the floorboards. See picture. Also, don't over tighten the screws. I had to order another as one of the screws pulled out.

I expected to fit 50mm pipe and seller will exchange it to me. Very good service. The product looks solid and seal good.

Wie beschrieben, alles gut geklappt. Schnell geliefert. So macht Einkaufen Spaß.

Etant professionnel j'adore ce produit je l 'installe sur tous mes chantiers. Un peu cher mais de très bonne qualité.

Muy bien
