I drained down the water at my mother in laws to move a basin and radiator. Now the central heating seems to run fine, however the hot water to all the taps keeps running dry after only a minute or so.
What I do know is the copper cylinder in the airing cupboard is filling up, as water is reaching the drain valve before it enters the cylinder although this maybe at a slow rate as when the drain tap is fully opened the water comes out at a slow enough rate that you can easily stop it by pressing your finger over it so not sure if that is normal.
I did not touch the gate valve in the water supply from the water tank in the loft to the copper cylinder in the tank when I drained the system down, and have subsequently checked the tap and fron an initial inspection by turning this it appears to operate fine.
I did notice that the hot water overflow pipe did actually bend over and go below the water level in the water tank in the loft, pressume the ballcock need adjusting however I have lifted the pipe up enough so now it is not in the water as wondered if this was causing an air lock of sort and in doing do pressuring the cylinder in the airing cupboard, however this has not cured the problem.
Any help would be very much appreciated.
Thanks
Jeremy
