I have what I believe is a 13 year old Weil McClain (I'd have to double check the age). It's been recently serviced and everything checked out great. It's running a 5 zones of heating and they all work without any problems. Efficiency seems to still be running great too.
Here's the quirky issue we're having with it. On occasion, sometimes once a day, sometimes every few days (and for no apparent reason), the exhaust will, for a lack of better term, "backfire". It's sometimes just a small pop like you're popping a plastic bag, sometimes it's a little bigger (usually startles the dogs). It'll happen at the start of the cycle or at the end. There's nothing consistent about it. Right now it's more of an annoyance since everything seems to work fine otherwise.
Usually what happens is it pops the cap off on the outside vent. It was doing this about once a week when the weather was warm and we weren't using the baseboard heating, so we had it serviced. I checked to make sure there was no blockage in the exhaust. The old vent pipe gaskets were in bad shape, so those should be replaced, and I did re-tape the pipe since the old tape was crumbling. The only thing out of place is the hose trap return line, the connection was corroded and is not properly attached.
Any thoughts would be greatly appreciated!
