It was mostly likely just a bit of scale, etc, that was causing the internal check valve to leak back through. Running the pump dislodged it, and it may be trouble free for years to come. I recently replaced an original pump for a fellow in a 1982 TT. The only reason it was replaced was because the previous owner hadn't winterized it before the freezing weather hit here in the northeast and it cracked. I could have replaced just the head and used the original motor, but given it's age the current owner and I agreed a complete new pump was the best option.Ok, here's the update:
DId turn off the park water and used the coach water pump to do some dishes, take a shower, etc. Then installed the pressure control valve (Renator Water Pressure Regulator Valve), turned off the pump and turned on the park water. Wait for it... wait... wait... well ok, looks like no leaks. Hours later still dry.
I guess it can't be know exactly what the problem or cure was, but for now at least I'm relieved to back to normal. We have a scheduled visit in a few weeks with an RV Repair guy who has done a lot of stuff for us in Jackson, MS, On that "to do" list was looking at upgrading our current water pump. Looks like good timing.
Many thanks to all the helpful suggestions!
