Wierd water leak
November 8th, 2009
I have a customer who says he has a leak, down thru the cavity for the stack, every fall for a couple of days when he turns his hydronic heating system on. House is two storeys + basement and the water ends up on the basement bathroom ceiling. Expansion tank is in the basement and there is no expansion tank upstairs. I was working is the house last week and there were no leaks while I was there.
The system, (forced HW?) is closed and if it were the heating system leaking, it would/should leak constantly since it’s under pressure at all times. I’d look elsewhere for the source of the water into the basement ceiling. Sounds more like it’s Plumbing related and a pure coincidence that it happens only when he fires up the heat.
