dying house water pump

Check and see if the pump is shutting off when you are running water. If so, it may not be a problem with the pump as much as clogged aerators on the faucets.

It was the pump. It was a pretty easy fix and amazing how much better the pressure is... Believe it's been malfunctioning since we bought the rig a year ago but the dealer of course said it was fine...

I am with you and would troubleshoot, and if that didn't work...I would get a new pump. Having installed a replacement before, not too bad and as long as the problem was within the pump, your problem will be solved!

We have an Aqua flow. Fifty psi 3 gal minute and quiet. Just make sure you have good sized wire for 10 amp and cooling air around it.

Depending on what you want to invest, you can probably rebuild yours. Usually the valve assembly on the front of the pump goes bad.

Or just the pump design itself. Some can put out high pressure...and some cant
