non return valves??

Hello all thank you so much for everyone's help. Hope it helps other people too. The issue is now resolved. I've changed washing machines. My wife's nan went to a home so we had her machine. Water tastes fine now??? And no leaks...... At the moment lol

I found out the best was proper Loctite superglue - there are cheaper versions of superglue in the pound shops and they were rubbish think they must water them down or something very runny and not as strong as Loctite. Thats good idea, never thought of a bicycle puncture repair kit to do it.

That's remarkable. I would never have expected superglue to hold under the stresses and strains of a bouncing drum and door seal. I used to use a bicycle tyre repair kit. With great success. I used to peel off the door seal and fix it to the back so it wouldn't be exposed to all the water. I'd roughen up the area with the supplied sandpaper and fit a large patch to it. Worked very well. Of course I always replaced the door seal as a first choice but sometimes the customer couldn't afford a new seal or it was decided a temporary repair would be OK.

yes i have done that before as well on washing machines where the door rubber gasket has had a couple of minor splits and fixed it with superglue and its lasted for ages

I have removed the hose and the inlet valve. I've cleaned the inlet valve up. I haven't looked at the hose but I shall do. The machine is also leaking now but unrelated as the rubber around the door has split slightly. I did manage to fix it awhile ago with layers of glue. Which has lasted about a year. But has now stared to drip through.

Hello Andy. Yes it may well be worth checking that. If it is related to this then of course it won't stop water backing backup into the water supply, it would just mean it less detectable if it isn't being contaminated. A permanent solution would still need to be getting a tap fitted that has anti-siphoning valve.

just a thought , have you removed the rubber washing machine water inlet hose and tried to clean out the inlet filter (a small round plastic mesh filter) maybe there is dirt/rust/limescale on the filters and its siphoning somehow back up to the drinking water tap? - i have known some machine manufacturers use metal filers and they have rusted - if you come across one of them see if you can change it to a plastic filter

It would have to be Google, Screwfix or a plumbers merchant

OK I can find plenty of taps with check valve but I need a tee version but they don't have check valves. Any other ideas

Try a Google search for non return tap and you will see more info and pics

Hi. The non return valve needs to be on the water tap to stop water from the fill hose that is trapped and under pressure because the washing machine isn't taking in water from getting back into the copper cold water pipework on the plumbing.

So there is no non return valve on a washing machine? Its been working fine the last few years I'm gonna clean out the inlet valve as I'm guessing it's a bit clogged up could this cause an issue like this. Thank you for your help people like you are a God send.
