The other day I went into my boiler room in my apartment building and noticed something odd, given it was 25 degrees out... none of the 6 zones were running and the boiler temperature was all the way down to about 80. The pilot light was on though. At first I thought a 24v transformer but neither the gas valve would work nor any of the 6 booster pumps, each run by relays. I did find a blown 15A fuse on the electrical panel. Long story short.... a little isolating and lots of luck... I finally found one of my Bell and Gossett 100 pumps was the root cause and I did measure a direct short to ground betwen the motor casing and one of the wires on the pump. I threw in a spare motor and all is good except for a slight water leak from yet another Bell and Gossett bearing assembly thats on my list of things to do and hopefully it will wait till spring before airlocking on me. Odd thing is that the water is weeping out of the oil port of the bearing assembly rather than from the bottom Just wanted to let you guys know something that may not happen often, although always a possibility.

Hello all.. I have a hot water heating system, two floors, seperate thermostats for each zone upstars and down. All was well untill I installed new baseboard in an upstairs bath replacing an old one. now I have no heat upstairs and I assume Its air locked. There are no bleeders on the baseboards... Can I just install a 1/4" tap valve (like on an icemaker) to the 3/4" copper return pipe at this new radiator? The boiler is putting out the same pressure as before about 22# however the temp is about 20 degrees cooler from 180 to 160. Thanks for any and all help with this matter. slim
