Pinnacle-Water Pump issue
We’ve got a 2016 Pinnacle 38flsa. Our issue is with the water pump. Sometimes, no problems. Other times, we switch on the pump and a terrible water hammer/vibration occurs for a good 3-5 seconds. Also, sometimes the water pressure is awful, other times, ok. We’ve replaced the shower head, replaced the water pump, verified that the unit is not in winterization mode and hooked it through city water instead of our usual dry camping. Nothing helps. Suggestion?
