Afternoon,
Anybody else have this problem with their setup?
In the process of testing the new oxyngenics shower head while using the water pump I think I may have stumbled upon the reason for the noisy water pump.
I noticed that it appears that the water pump is being starved for water. By starved I mean that I could actually see water flowing through the opaque fitting and the prepump filter bowl on the inlet side. This would seem to me that the pump is pushing it out faster then the supply can keep up which is making the pump vibrate more.
The water supply line that feeds the pump is a smaller diameter line then the one that it conncects to on the other end at the water tank outlet line so I'm wondering if that isn't the problem and if I can just replace that particular feed line with a bigger one.
Any thoughts appreciated.

If you can "see" water, it probably has air bubbles in it. Look for a leak on the pump intake side (between pump and tank).

Hello Letsgoagin,

If your pump is a Surflo 2088-422 series; then they are inherently noisy.

Two things you might look at. Are your water lines to and from the pump hard plastic. My '01 Dip was hard plastic lines. Sureflo mounting instructions call for minimum 12" flexible lines on both intake and output sides of the pump. I inserted 14" steel braided water lines and that cut the noise in half. My prepump filter is clear and it has some air bubbles in it. Originally my filter was mounted on its side and had some bubbles. Now it is vertical. Still have some small bubbles. My lines are all tight, so I suspect that the design and construction contributes to a small amount of air retention.

Hpe this helps,
