Water pump

The water pump in our 2019 27’ GT only seems to work smoothly if both kitchen and bath faucets are running at the same time. If just one or the other is running, the pump “thumps” and the water comes out pulsating... defective? Air in the line?

I installed an accumulator to help solve for this.

The pump is supplying more water than the faucet can handle. The pump is cycling on and off as the pressure builds up and then drops. With two faucets open, the pump is running constantly to keep up with the demand.

Yes it's normal and happens for the reason Richard explained. It's worse in some trailers than others but it can be mitigated to some degree.

First and easiest thing to do is make sure your water heater has an air gap, see your water heater manual. This works something like an accumulator.

Consider adding an accumulator as wulfrrat did and/or this pump silencing kit.

Lastly if you have pipes that are rattling and you can access them you can slip a piece of foam pipe insulation over them.

I've done all of the above with fairly good results.

Interesting. Where did you install the accumulator?

You can install it anywhere within the pressurized cold water plumbing system. In my case I stuck it under the sink.

I have one out of a '76, just pay shipping and my require some plumbing fittings, but it's all metal (i'm guessing stainless).

No pic, sorry. I mounted it to the back of the sink enclosure. Plumbing was simple.

I also installed the accumulator and the pump silencing kit, both from Surflow. While I was at it I put foam tubing, normally used for insulating pipes from the cold (get it at any big box hardware store) around any of the pipes near the pump that we’re contacting anything else. I did all of this down near the pump, under the hall closet in a 25’.

Makes a significant difference.

Thanks for the question and the answers. I have the pulsing particularly bad on my bathroom sink. Now I understand why it only happens with the cold water. Now I know how to fix it.
