C/H header tank feed pipe pushing hot water into tank
Hi all
Not actually name Ron but i am using my late uncles name as i did my apprentiship with him back in the late sixties. I have not worked as a plumber for a number of years at least 30 years but still enjoy the odd job for family. The problem below is happening at work and is in a two storey building, boiler ground floor cylinder ground floor and header tank in the loft of a two storey building.
Hot water is Gravity fed, heating is pumped system.header tank is filling up via the feed pipe and the water is hot, and no water appears to be coming out of the expansion pipe. The rate of overflow is probably about a litre per 4 hours
Pump on middle setting. No other problems with system. Only appears to happen when the heating is on, but will check tomorrow to see if it happens when on hotwater only.
Any suggestions gladly appreciated
cheers
John alias Ron
