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.
There are operational pipes half way up, three are two capped off holes. The only pipes are at the top two 15 mm copper pipes and what looks linch inch lead pipe. There appears to be lead inlet pipe at the bottom also.
