Pressure gauge failure?

Hi Everyone.

Starting on fourth year of DE filter. Pressure gauge has stayed at 21 psi for two weeks. This is the normal psi after backflush and adding new de.

So I'll just replace it. Is this a common four year life item?

Thanks

I'm not sure I understand the question. Do you mean that the gauge is showing 21 psi after backwashing and adding new, and that it is an increase over what it has always been before? If yes, then it's probably time for a new gauge. Anytime they get wet and then freeze, they go bad. If you removed it during winterization and it got dropped or banged around, that could have done it too. Because my pump stays in operation 12 months out of the year, I generally lose a new gauge each season--but they don't cost that much to replace.

Sorry for the confusion. After backwash it always shows 21 psi as it does now. Problem is that the psi has not moved for two weeks. Glad to know they are not costly and I'll get a new one this week.

Thank you.

If your water is clear and there is very little to filter out, then it's possible that the gauge isn't malfunctioning. Are you filtering out enough "stuff" that you think it should have risen by now? My filter can often go 2-3 months without needing to be backwashed, because there's very little stuff for it to filter out.

I have lots of trees and this time of year lots of tree stuff in the pool. Water is clear and the inlet flow does indeed seem strong. I'll wait another week to see if I have psi increase. Thanks

check the gauge with the pump off- if it returns to 0, then 21 when you turn pump on, it's probably ok...
if it stays at 21, its stuck and go ahead and replace...

A few days ago I did that: turned the pump off it still said 21. I tapped it and it went to zero. Then pump back on and it went to 21.

However, today it reads 24, soooo I think it just may be ok? Water still crystal clear.

Thanks again everyone

if it still hangs when you turn pump off, I'd replace it; about $10 at Home Depot, 5 minutes to replace

That inexpensive, I will do it. Thanks
