Anyone have any experience diagnosing/repairing the freshwater pumps on a 41 Open or similar Tiara design. The system was working fine however after emptying the tank for spring commissioning the system would not prime. There are two pumps, one is a Flojet Water Pressure System pump model R4305-500 and the second is a Flojet Washdown pump model R4325-143. I'm assuming the R4305 is controlled by Pump #1 on the DC panel and the R4305 is controlled by Pump #2 on the DC panel but that is an assumption.
When I turn Pump #1 on nothing happens. When I turn Pump #2 on both pumps turn on but still will not build water pressure. I disconnected the water line to the R4305 and I get some suction when I put my finger over the intake but have no way of telling if it is enough. In addition I removed the air vent hose at the water tank thinking that a blockage may be preventing water flow but that made no significant change.
Any help appreciated.
