Once again, I turn to this forum as a problem solving resource. My 2014 Scamp
16' with a forward bath has a Shurflo transfer pump to move shower and sink water to the back of the trailer where the grey water tank is mounted. (I'll hold my grumbles about that design for a later time.)
When the sink is full, or the shower is running, the user switches on the pump to move the waste water back. We're on the road, and have been using the pump normally until yesterday, when it suddenly stopped transferring water. It runs, so I cleaned the filter, and took the pump apart and cleaned it out, finding a possible stuck check valve, but on reassembly, it still doesn't transfer water. All connections seem tight, but putting fresh pipe thread tape on ALL the connections is my next shot.
Any other ideas? I'm a little surprised to have it fail so suddenly in the middle of a trip.
As always, thanks so much!
