Re: Priming a hot water recirculating pump
There may be air in the line. To purge it, you may be able to open up the line on the downstream side of the pump.
Also, look at the pump body. There should be a flow direction arrow; make sure it's pointing the right direction.
If there is a check valve in the line, make sure that's pointing the right direction, too.
