My pump won't come on, but the burner is working. I've checked the voltage at the pump, & get zero reading. What could be causing this? Could the end switch on the zone valve be faulty? I have 4 zone vales, & it works the same on each of them. :HF2:

K we moved into this house and pulled the old BB covers against my better judgement. I want to strip and re paint them SHEEEEEEEEEEEEEEEEEE wanted new. Well the old BB fins are size-ably larger than the new style and i had to pretty much force the covers to snap into place. I am beleiveing that when they heat up they expand and its rubbing against the covers. On top of that the dummy boards didnt come with any plastic covers for the fin hooks and the old BB fins didnt have them on them. In the Bathroom and last run in the Living room i got so frustrate i ended up taking my thumb and from the beginning of the runs ran it down to the end bending each fin in about 1/4" to make them a tad smaller to get the faces on. My question is (and i used to do P&H lol) do you guys think this will affect the heating of the house if i did this to all of them? These appear to make the least noise but because there is SO much BB in this house (its a direct run one pipe through the whole place) I cant tell if it has in those areas. I wanted to rub them all down about 1/4" and then place some kind of plastic shim between the hooks and fins since i think thats rubbing and making noise too. So second question, does anyone have a suggestion on some material i can use as a shim without dealing with burning plastic. I know they dont get that hot but still. BSTS i always say, well not always ive been know to get frustrated and do some dumb stuff.
