Hi,
I have a very old gravity fed hot water system in my roof (no idea of model). I need to shut off the hot water to change some tap washers. How do I do this????
Shutting off the mains does no good, there is an input tap to the system, but turning this off is no good. I cannot find any tap on the output of the heater. The only thing I can think of is turning off the input tap to the heater and draining the system, but this seems like a pain.
Is this normal with an old system or is there an easier way??? Any advice is appreciated. BTW I am in AUS.
Thanks,
James
