I was wondering if this is a rare thing or a common problem. We had a water pump failure while boondocking in southern Arizona. Contacted Heartland and received great support and was directed to a very accomodating repair facility in Mesa Az where the pump was replaced.That all happened on Thuirsday. We got up on Saturday and the new pump had already failed. I checked all connections and voltage to the pump and all is good. This is on a shurflo 5.7 pump. Anybody else having similar problems? Just curious.
