|In response to Re: Yet another pipe noise questions...|
: I just moved into an old house with a large addition (10 yrs old). It seems that during and after the furnace is running, the baseboard pipes in the addition bubble and gurgle and then it actually sounds as if the water is draining somewhere. I don't mind the bubbling sound, but the draining sound is pretty loud. Any suggestions?
If the system is forced hot water, sounds like (pun not intended) you have air trapped in the hot water system. If it was designed properly, you should find vent valves at the highest point(s) of the system (could be within a baseboard cover). They may look like a small knurled knob on the top of the pipe. If you can find them, crack them open while the circulating pump is operating and air should escape. When water starts seeping from the vent, close it. Do this carefully, the water could be very hot.
