psi

Hi everybody, pool newbie here and need advice. My pool construction is nearly complete. Waiting on plaster, water, and start up. My hardscaping around the pool is done. A few days ago my PB asked me to check the PSI pressure at my equipment pad, up to that point I was clueless about the...

Hey all, I have a 36,000L underground salt-water pool. The pool is about 15 years old. When running smoothly, the PSI is always at a nice 17 which is what the installers mentioned when we first bought the pool. One thing I am not understanding though is... why does this lower to 12 when I open...

Hi everyone! In a nutshell, I feel like I've never seen my gauge increase more than few PSI following a backwash. It runs around 16psi --- and can stay that way for weeks. Invariably, I get antsy and choose to backwash even though water flow from the returns feels good. Could this just be a...

I followed the guide, but even after two full cups of DE the pressure in my filter did not rise at all. The guide didn’t really indicate whether going beyond two cups was safe or not, so I have not tried any more than the two cups. Why am I not seeing any change in pressure after adding two...

HI everyone. New pool and new equipment. Pump is Hayward TriStar VS SP3202VSP. I'm trying to get accurate TDH calculations so I can properly configure this to be energy efficient. I picked up a vacuum gauge and a pressure gauge and hooked them up to the pump ports and got the following...

Weirdest question I think I have ever presented to you all - Just finished a revamp on my 40 year old pool - new cooping, tile and surfacing (drain hole plugged). Replaced pump and motor for prosperity, as well. Cleaned and replaced the filters. Everything is clean, clear and running really...

My 72 year old (female) Friend had an algae problem caused by a broken pump motor and a lot of leaves. I replaced to broken motor, cleaned to DE Filter, got as many of the leaves out as possible without being able to see the bottom of the pool. I Shocked the pool and ran the pump until my...
