Wirquin 90 mm Slim Shower Waste Membrane Trap 40 mm Height

Easy part to fit Good quality part

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!

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

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

Ideal where there's limited access, easy to install works perfectly 👍

Very good quality
