Have a 2012-2560RL. Been holding up ok. Just went to winterize plumbing with antifreeze and activated pump (we had poured in 6 gallons antifreeze into fresh water holding tank) It stopped with the typical tut-tut-tut as if full pressure was reached in lines. We opened faucets and nothing came out. No hiss of air in the lines either. A dribble of water came out of 2 of the faucets but stopped almost immediately. Nothing from the other 2. We are guessing the pump is blocked somewhere or has failed. Bypass has been tested in both open and closed and no pink or anything even close moved in the tubing. Worked fine when we took it out of winter mode but not now. So...ideas welcome if you have them. The big question is where is this thing mounted?? We are handy and I have the pump schematic but our undercarriage is covered and intact so I’d rather not slice and dice with at lease some idea of the location. In all of this we saw no leaks anywhere but that won’t be the case if the forecast holds for Saturday!
Thanks!
