low pressure

Hello! I wonder if anyone can help. I am about to replace filter sand with filter balls as approved by the filter manufacturer. I am assuming that the need for this, which hasn't been done for at least five years, has contributed to low filter pressure which seems to affect the vacuum system -...

The pump recently started to not push water to the upper waterfall on low speed (1,725 rpm). It has for years not had a problem. The waterfall is about 3ft higher than the pump. I can see that it is pushing water through the pool outlets, just not enough to reach the upper waterfall...

We recently had our 25 year old pool and spa renovated - new waterline tile, pebble finish, etc. The spa jets were tossed during their demo and as such they had to order replacements which finally arrived today. They installed the replacement jets today and we have a few problems: 1. When in...

Hi everyone, I'm at the end of my rope... I'm sure I have a blockage somewhere but can't get any pool professional to help me. I've had 3 people here and no help, the last one told me not to call him again, there was nothing he could do, and he didn't even try to troubleshoot the problem, and...

The issue started this season. My Hayward hp21104t would flip the circuit breaker after running for a few hours. Now it's throwing a LP (Low Pressure) error and won't start at all. Based on my limited knowledge and research, this error is related to refrigerant but can really be thrown because...

We've had a 24' above ground for about 15 years now. Over this time I have "experimented" with multiple setup. The last couple of years I've been using a sand filter (second hand given to me) . This spring I was gifted a new sand filter (Blue Devil) which came with the multivalve. I also...

So not to long ago, I thoroughly backwashed my Hayward Pro Grid DE filter 48 square feet. Also before that I clean out each individual grid, there were no rips or tears however I did find some broken plastic inside a few of them, but not incredibly broken. After putting everything together and...

Just replaced a defective gauge and pressure was 12 for 2 weeks. Yesterday it was registering 6, so low the heater would not engage. When I turn on all 4 deck jets the pressure increases to 12. Any ideas? Is a pressure of 6 acceptable? is it possible the new gauge is defective? Than you,

Hello! My fiancé and I just recently bought a house with a large (26000 gallon) inground pool & we have never had any pools before. When we first moved in (in December ‘18) everything was running great but since March we’ve been having a lot of trouble with our filter/pump. When we turn the...

I had a new Rheem heat pump installed about 2 months ago. Before that, I replaced my single-speed pump with a variable-speed, which I mostly left with the default settings (couple hours high speed, 10 hours low speed, couple more or so at mid-speed). After installing the heat pump, I adjusted...
