We installed some new taps at a friends flat. Slight problem in that we couldnt find the stopcock (subssequently discover its in next doors flat...go figure!)
Anyway, we managed to isolate the kitchen sink ok and installed the new taps.
Now, problem is, that once all the valves we shut off were re-opened, no hot water came back in to fill the storage tank (or at least if it is, its doing it at a dribble..)
The storagfe tank had to be drained down to perform the works, but cant work out why no water is coming in to re-fill the system.
The system is of a sealed typ (no open header tank). There is a grey pressure vessel in the loft crawlspace that has a red valve on top that hisses when turned, and a pressure guage on it. The pressure guage reads 0 atm, but will rise a little (to a 1/4 bar) if left overnight.. I assume this is the pressure releife system, as its hooked into the drain pipe that pokes out of the outside wall..
If we leavce the system for several hours, the tank seems to fill a bit, but turning a tap on quickly drains this (in like 15 seconds..) We had the gas turned off as well, but that is now back on and the pilot on the boiler is lit.
Im stumped.
Any sugestions people?
