Great service and product
I bought this valve to control bath outflow. Unfortunately the courier (Royal Mail) seem to have misplaced it along the way so by the time it arrived I had already fitted an alternative. However the Senriseuk valve is a far superior product to the one I fitted so I'll be replacing it asap. The service offered by Senriseuk is exceptional and they did everything in their power to solve the non-delivery problem. I cannot praise their service and prompt response times enough. A great product and excellent service. Highly recommend.

works very well
I had a non return valve which was a ball and spring type That either stuck and stopped the flow or didn't seat and let the water flow back past it I bought this swing valve to replace it and for my application pumping dirty water it has worked flawlessly and at a better price so I would recommend this valve It relies on the back flow to close the valve and thts a much better solution

Looks robust and seems to work well
Using it to allow me to connect the outlets on my caravan without water flushing back into the shower tray. only used it once but seems to work well. fitting was reasonably easy, it looks quite robust so hopefully will last a long time.

Not for standard 32mm solvent weld waste pipe
Be aware this is 32mm outside diameter so won't fit 32mm Floplast solvent weld waste pipe which is nearer 36mm OD. The valve opening reduces to about 25mm, so could cause some pressure build up.
