Can some one help I have a 2018 sunset trail and the water pump works fine but just recently it’s making load vibrating noises . I opened hatch and everything seems fine but sounds loud . Any advice
Add a piece of foam or rubber under the pump for starters. Isolating the pump from the floor often takes care of a lot of the noise. If the PEX lines go directly to the pump you can also add some short flexible supply lines between the pump and PEX. One or both should take care of the problem.
Actually the pump should have rubber bumpers under the feet where it fastens down to the floor. Some times these screws get tightened down to much. When that happens it defeats the purpose of them being there.
Mine started hammering way louder than normal. Two days later it started to leak. Turned out to be a broken diaphragm. Replaced pump and all is quiet again.
Try putting some foam pipe insulation around the pex water lines in the compartment where the pump is. Those lines vibrate thus rattling make noise. You may also want to upgrade to a higher quality quieter pump.
