Dear RV Doctor:
We need to know if our expectations are unrealistic about our fresh-water pump. We recently replaced the SHURflo 5900 pump in our motorhome with a SHURflo 4048 High Flow Pump, because the 5900 is no longer offered. But the 4048 causes the 12-volt lights to flicker. The performance of the pump itself is far inferior — but that’s not electrical; that’s a SHURflo issue. That said, what might be causing the flicker?
