heating pipe blocked? heat 1/2 house.

Butch_4 Member Posts: 19
Replaced a zone valve yesterday. When I did the soldering where we had to cut the pipe water was still dripping. My neighbor suggested bread in the pipe to soak up the water to get the fitting soldered. Zone valve works fine. Problem is now we only get heat in bathroom and 3 bedrooms. Nothing in kitchen, living room and dining room. When the water comes through the zone valve it travels to the t joint. There it branches to 2 parts of the upstairs and there (I'm pretty sure) is where the problem is. To the left of the t it is hot when calling for heat. Straight ahead it is barely lukewarm. Think it is only that way from the heat radiating. This was fine before. Will the bread from the hot dog roll disolve? Is there anything I can do. I know this sounds stupid. Please do laugh to hard.

    Hi Butch

    DO you have a means of purging the 2 zones? I personally would never put any foreign objects in the line, but I would think the bread would dissolve. I think the "Old Timers" used to do something like that.

    Breaking Bread

    Air got in during your repair and has to be purged as suggested by others! The bread DOES dissolve ,and pretty quickly.I use/carry on my truck a product named "Plumbers Bread" by Sterling Joining Technologies, 1/2 " and 3/4 " plugs.I joined AARP (a few years back)so I guess that puts me in the "old timers "group. oh well!

    like you have a split loop. You must purge both sides of the loop seperately. The purge setups,hopefully it has them, can be very elusive to find, possibly at the other end of the basement, hidden in the ceiling, etc. The idea was to carry the split loops back on one common pipe to the boiler to save pipe.
