During the recent cold spell one of my hot-water heating pipes froze
and cracked. I would like to determine which one to replace without
spending too much time in my 2' crawlspace. Can you tell me if the
following would work:
1. Close both ends of the loop at the heater.
2. At the baseboard in the middle of the loop, undo one side so you
have access to the pipe that goes into the basement.
3. Make a little gadget that you solder onto this pipe. The gadget
lets you pump in air using a bicycle pump and shows you whether
anything is leaking.
4. Repeat process until you know which is the bad pipe.
Does this sound like it could work? Any and all advice would be
appreciated, it's going to be really cold over the weekend :>
Also, once the pipes are repaired, how do I "start up" the cycle
without introducing air? I have two heating zones and one's working as
is my shower water and I don't want to lose that. Any pointers to
sources of info would be great.
Thanks a bunch in advance,
