to check the pumps you can change the power supply wire from the outside
post to the center post on the relay and get constant 12V power to the pumps.
Then take a light and look in the resiviour tanks and see if you get the
stream of water flowing into the tanks. If its there and strong then your
pumps
are ok. If not replacement would be a considered option. Bennie with BB told
me about switching the wires to test the pumps. Call him if you have
questions. David with Vehicle Systems agreed that the weak part of all
hydronic
systems is the circ pumps
