" Solves all sorts of back flow problems in bathrooms, and is easy to install. A tad pricey, but works fine. "

Great product poor stock level

" 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. "
