No need to return!
20 May 2015
By Talksense

" I needed a non-return valve to prevent dirty and smelly waste water from returning into my washing machine from the soil pipework. I purchased and installed this and the problem was solved. Easy to fit although working in a confined space under the sink is always tricky! "

Great product poor stock level
4 Jan 2014
By IKAR

" Good item, good quality, does exactly what it should and that is to stop the back flow of water. I would recommend this product.
Needed quite a few of these to fit in a block of flats but each Screwfix only stocks 1 of these at a time which is very disappointing and meant that I had to pay more money elsewhere and waste a lot of time locating them. "

Good Waste non return valve

" This is a good non return valve, however it must be said that you need to be careful that the actual valve part inside is sitting correctly, otherwise it will leak, or you could loose it inside the piping ! "
