Pump pressure problem

[techman65]

Hi all,

I am having trouble with my pump pressure currently. For background:

I recently replaced my pump motor which I posted about in a different thread. Water is circulating fine now, but my pressure is not changing even though my pool is dark green. I have backwashed multiple times to no avail.

My skimmer and pump baskets are clean. My pressure gauge is relatively new -- replaced in the past year or so. It is one of the glycerin filled ones from TFTESTKITS. Since the pump motor was replaced the gauge is constantly at the setting in the attached photo.

Any suggestions on things to try and resolve the issue? Thanks.

That looks like the pressure is way over 30. Does the gauge go to zero when pump is off.

It goes to this pressure after you backwash? Either your filter is very dirty and may need a deep clean, or the gauge is broken (potentially due to very high pressure).

Deep Cleaning a Sand Filter

This post will walk you through the anatomy of a sand filter, and then provide a video at the end for how to deep clean your sand filter. The filter used in the photos and videos is a Hayward S180T top mount sand filter. The images are of a similar filter. Obviously not all filters are...

Hi PoolStored,

Thanks for your reply. The gauge does not go to zero when the pump is off. It shows around 28 psi. Do you think the gauge needs to be replaced again? Thanks.

Yes, it may have been damaged with very high pressure due to rapid rise in pressure as you were circulating green stuff through the filter.

65,

The gauge is bad, just replace it.

Thanks,

This is normally due to freezing.

In any case, just replace the gauge.

Thanks! I ordered a new gauge last night from TFTESTKITS and will report back once it arrives and I get it installed.

Just wanted to close the loop on this thread. I received the new gauge and everything is now working as expected. Thanks for all your assistance.
