I have asked this question before about the noise of the vacuum pump on a 2019 Southwind vacu flush toilet. Every time the toilet is flushed people from 100 ft. radius want to know what the noise is. The noise inside of the coach is manageable but outside is very distracting to fellow campers but a bit of a privacy issue.
I have called the rev customer service and the tech dept. and they have not have had any complaints so the question is, is my unit louder than others or am I just too sensitive. I took off the access panel and the pump is mounted to the floor with no rubber barrier between pump and floor and the pump is enclosed in a metal compartment so the pump is virtually enclosed in a drum. I wish I had heard this noise before purchasing the unit I would not have bought it. I have seen the vacu flush system on boats and there was no noise. Customer service has told me to have the dealer check the pump and have them take pictures and call the warranty dept. that will be done this April when I get home.
I am looking from input from other vacu flush users. Thanks, Greg
