Hi all,
Novice question here. My mom's house has 4 zones running off a Taco SR 504 switching relay. This morning she noticed that the one zone (sun room) isn't warm. Baseboards (hot water oil) are cold. I just went up to look at things. Turn thermo way up above room temp, hear click on control panel, went to basement, red light is on on SR as expected. That for me rules out thermo and switching relay. Next thought was air lock in the zone since I've had that happen in my house once. I can't seem to find a place to bleed only the one zone, but that might not be relevant right now. I turned down the themo and cranked up another zone and went down to listen to the cartridge circulator on that zone and hearing the slight whiring of what I assume is an impeller in the unit which makes the water move. Ok, turned that good zone back to normal temp so it's not running, cranked up bad zone again, no noise on the circulator.
Do these things just go? The house is 7 years old. I did notice that while the model/make is the same as well as all specs on the sticker, this one is black vs green and looks kind of corroded.
The circulator is a Taco model 007-F5 with the following specs:
hp: 1/25
amp: .71
hz: 60
volts: 115
rpm: 3250
psi max: 125
max h2o temp: 240f
If it is this, it's beyond my plumbing expertise so I will have to call someone (we're in northeast PA). Figured I might call my local plumbing supply house to at least get an idea on part price, knowing there's other parts like fittings and such that will be needed.
thanks!
