Rated 5 out of 5 by from Experienced DIYer Possibly more importantly than any other the other info and specs, is that it is made of metal. Make sure you buy washers for it, my recommendation is one rubber and one fibre washer at each end, left me with zero leaks.

Rated 4 out of 5 by from Legionella Prevention While Legionella is relatively rare in the domestic home, nevertheless the risk is there. If, especially, like me, you leave home for weeks on end, or your hot water boiler is fed from a tank. This small item will stop the back flow of contaminated water into the system. A small price to pay in order to keep you and your family safe.

Rated 5 out of 5 by from Single Check Valve Standard shower valves come with single check valves. If your shower hose reaches below the spill over level of the bath or shower tray and you are looking for a Water Regulations compliance product adding this to the shower valve hose outlet will give you that compliance. We've used a few and had no issues

Rated 2 out of 5 by from Why No Supplied Washer If you buy this you will not be able to fit it until you buy a rubber washer - why on earth the manufacturer does not supply one for an extra couple of pence on the price is beyond me.... Quality of the product is OK, reliability is unknown as only just bought it.

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

i have a shower attached to the mixe tap and have bought a new hose with a half inch ips attachment which won't connect to my taps, although the taps have 1/2 inch attachment it won't fit. I want to find a converter, would this work please?,

Asked by: Chris200

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.
