Hi, I’m trying to diagnose my cabin water pump flow problem on my westy. I can use city water hookup and have good pressure at faucets. When I turn on my pump and try to use tank water I get no flow through the faucets with the pump on. I disconnected the pump from the outflow tube and have good water pressure outflow at the submersible pump. When I first noticed the problem the pump had popped off the outflow tube. I thought reconnecting it might fix the problem but not so. Any idea as to why water won’t move forward from the pump? Worked just fine previously.
