Know this is an older thread but our water pump started being VERY noisy last month while we were in New Mexico. Then it stopped working. Dealer found a loose wire and pump now working again but very noisy. Was not that way until last month. So, the question - have others experienced this same issue as the water pump is used more. It used to be that you could barely hear it working, if at all. Now it sounds like someone is hitting the floor with a hammer hundred of times a second (exaggeration a bit but is very loud and consistent with water usage - the more being used, the faster it becomes.).
Personally I feel that the pump is failing / has failed but need some experienced folks to let me know if so.
Thanks.
