Which direction allows the flow of water? Left side to right side?

Asked by: avii
Hello avii with this non return valve the thread end screws into the water fitting and the outlet screws into the outlet. If you are unsure please consult a qualified plumber. Thank you for using the Screwfix Q&A service

Will this stop water coming out hose when switched off as leaking if not what will please

Shower is galaxy 7000
Asked by: Anonymous
Hello, Thank you for your enquiry. This part is designed to prevent a shower hose basically sucking up water if say left immersed in a bath full of water and back into the water supply. It sounds like you will need to fit new fittings/seals to prevent your hose leaking. Hope that helps. Thank you for using Q&A. MH

Is this WRAS approved?

Does this safely prevent back flow contamination of a shower head that could be submerged in water? Does this eliminate the need of a retaining clip on the riser rail?
Asked by: DCPlumbing
Hi DCPlumbing, As far as we are aware, this is not WRAS approved. It is normally fitted between the shower mixer and the shower hose to prevent possible back siphonage and contamination, not at the top end of the hose below the handset. I hope this information is of help to you.
