Rated 4 out of 5 by from Solving Connection Problem As previous posts point out one end is 40mm the other end is 32mm (June 2020) made to fit directly onto a 32mm sink waste plug fitting. How I made this product work was by buying a 32mmx 40mm straight connector MCALPINE ST28M STRAIGHT CONNECTOR WHITE 32MM X 40MM (95260) Take the 32mm nut off of the straight connector to reveal the thread, screw this thread directly onto the 32mm end of the valve and voila, it now fits in-line 40mm each end. Remember to get the water flowing the right way through the valve.

Rated 4 out of 5 by from Ideal for tight space Great product little expensive but never failed yet have used a few of them. It’s worth pointing out that one end screws on to plug waste so if you are not directly connecting to the plug waste then you will need a 32mm adaptor to connect to not a 40mm

Rated 4 out of 5 by from Plumbing Bit expensive, but does exactly what it should. Would use again.

Rated 4 out of 5 by from OK Great idea. What's not made clear on the description that says it's 40mm is that it actually has a 32mm inlet.

Which waste pipe do I use with this - push-fit or solvent weld? Thanks

Asked by: garygang

Will this be OK with Insinkerator & dishwasher

Will this work with an Insinkerator, if a dishwasher is also connected to the dishwasher port on the Insinkerator, so that all the waste from the kitchen sink and dishwasher would flow into a single Osma HepVO?
Asked by: 4eyesbetterthan2

are there any other attachments needed to connect 40mm to 40mm pipe

Asked by: swampy86

Description - Dry trap

This is better known as a Dry Trap, not a valve. Also the description for the end fittings need improvement, one end I suspect is a 40mm compression, the other end will be usually threaded needing couplings of some form. Kind regards

Can this be installed vertically?

Asked by: LazyBadger
These units can be mounted vertically and must be mounted this way for specific uses. Garbage Disposal (Vertical Only) Urinal (Vertical Only)
