Two times in the last two days when I fire up my Tarm I've got some decent thumping and I traced it back to the loading unit. I've always run the pump on 3, that's the way it came to me, by slowing it down to 2 or 1 the thumping goes away.
I'm not sure if the valve is getting stuck and causing this problem or something else.
The first time is happened a zone opened up and that stopped the thumping. Typically when I start the Tarm I have a few zones calling for heat but it's getting warmer, so I guess that's something to factor in as well.
Anyone else every experience this? I've been meaning to try the pump on 2 anyway, I've been wondering if I was moving water a bit to quickly and not getting as much heat transfer.
