Plumbing Question

One way valve for a shower waste?

Hi, does anyone know if there is a one way valve that could fit onto a shower waste pipe to allow water to drain away but not come back up the pipe? Is there a valve that is not for a pressurised system?
Thanks

Hi,
Hepworth straight through trap is a great thing!!, you will have to remove the old waist and fit it in line not quight sure why you need one though as the waste should have enough fall to drain under gravity and have no back pressure, you will as stated above need to have the falls checked on your pipes.
you may just have a small build up of junk!!

Hepworth do a straight through trap, you need to get the adapter with it and then you can fit it inline into your 1.5inch waste pipe. Not sure why you need one though as the waste should drain under gravity and have no back pressure, you need to check the falls on your pipes.

Hi Check the fall on your waste pipe sounds like it might be running up hill, or may be blocked. Gravity will do the trick but your waste pipe has to have a fall on it. Hepworth do a one way inline waste trap but this is to stop the smell of the drains coming back, dont think it will stop water. Thanks Steve Wynne
