We have noticed a low pitched noise each time we turn on the water. It stops when the water is turned off, but happens whether it is the toilet, sink or washer. I checked the water pressure regulator and it is showing 40 lbs and is labeled preset to 40-50 lbs, so that appears to be normal. Any ideas as to what would cause this and a possible cure?

I believe this condition is caused by Floridians traveling too far north.

Could be, I thought originally it might be hard water. It is rumored that this also happens if you travel west.

Sounds like the coach is worn out. Time for a new one. Maybe it's all that northern water flowing thru them southern pipes.
Sorry Larry, I don't know what would cause that noise.

Derek,

We have had it for over a year. I think we are getting behind the average Florida Boomer trade limit.

What about the check valve (back flow preventer)?

Could it be the water pump itself? Mine makes rather a lot of noise when it is running.

I don't think it is the water pump, as we are on city water supply and the pump is turned off. The backflow preventer could be the answer, but I will try to find it and determine if that is it.

Listen for the noise around the water heater area. There should be check valves there and at times they can cause the noise you discribe.

The clue is you hear he noise only when you use a water appliance. I am almost positive that what you're hearing is the water pump.
Suggestion - locate the water pump where you can see and hear it operate; have your sig other turn on a water faucet and see if the pump operates. If the pump operates, and it is switched off, you may have a short either in the switch or in the pump. Another test is to disconnect your water hose and run a faucet. If you get water, you are definitely running the water pump.
As far as the pressure regulator reading 40-50 lbs. - all that means is that the site hookup is supplying that pressure at the regulator. Good luck...

If the process suggested by rayw does not find it, you might look for a variation on the idea from rv2352 -- if it is not the checkvalve (some of which use springs to make the closure) in the rig itself: are you connected to a anti-siphon water faucet? Some of those create a low-pitch vibration/growl.
