this sounds like a good idea however I do not know what position the lever should be in, I have just moved it from one side to the other and then the middle and did not know what for.
ok, i will try and find air block. i understand the new valve does need replacing it was a needs must situation, however the ch is working fine, it is the hw that is not.
i do apologise, the pipe on top of the cylinder without the valve comes from the 3 way valve and gets hot, the other one with the valve goes through the floor.
your asking the wrong bloke! I have not altered anything except leaky valve on cylinder. I know it is a washing machine valve but as the water leaked through my floor I changed it immediately, the only spare I had was that one. I will change it back once sort the hot water problem out.
i tried to upload some pics of my 3 way valve but I just cannot figure that out yet. Will keep trying. Thanks for all the assistance so far, it is really good.
