high pressure

I've recently moved into a house with a pool, and as a complete novice, I had zero communication with the previous owner about how the system works. A few weeks ago, while trying to map out the system and understand what each component does, I noticed that my filter pressure gauge was reading 35...

It has been a horrible pool season for me today the least … Fine on filter Fine on rinse Fine on waste Backwash? High pressure and no water movement. I’ve remove MPV and moved the sand around in case of possible sand hardening or channeling. Nodda. HELP!!

Hello, I have been having an issue since last year where after about an hour of running at normal pressure the pressure in my 60 sqft DE filter grows to the max over 50 PSI which then either causes my pump to lose prime or causes a large air pocket in the pump basket. I have replaced the pump...

Hi - "Just the facts, ma'am..." ;) My brother has a 10,000 gallon uncovered shaded pool at his personal and rental home in Mexico with a Pentair Intelliflo VSF pump, Hayward Pro Series 3.1 sq.ft. sand filter and a 480 sq.ft. roof-mounted solar hot water array three stories above the pool. The...

Good day everyone! I recently got a house with a pool in Phoenix, AZ. When I got the house, it took me a month to move from Texas, so I got a Pool guy to clean the pool while I was away, who ended up letting the pool turn green. The guy installed new DE Filter grids since the filters had some...

I just started taking care of a pool and don't have much background knowledge. Problem: From what I've deduced, there is a three-way valve (see pics) on the return line that sends filtered water back to either a return jet or a side return (with a pressure-driven cleaner attached). When the...

Hello, Any help would be awesome. We curenlty opened our pool (First time for us just moved in) and the water is perfect and clear. Talking to the neighbor it seems my filter is running super high pressure. When running it is steady at 45Lbs. When its not running it stays at 25lbs. Not sure...

Hi all: I am a pool newbie. Moved into a house over the winter and ignored the pool .. Now I am starting it back up. The pool was green. Pool is in ground, large and with a DE filter. Heres what I did: 1. Brough the TA and PH to range 2. Then I shocked the pool with calcium hypo shock. Once i...

My pump pressure is running high lately even after hosing down the cartridge 3-4 times. It starts at 8 psi and in 20 minutes or so, goes up to 16 psi. I had a lot of algae in it last month as I was out of town for several weeks. I ended up shocking the pool and washing the cartridge, but still...

I have a 15,000 gallon inground pool with main drain/skimmer/(2) returns, S180T filter and a Power Flo LX 1.5SPL pump. I have no problems getting it to Prime and I have zero issues when in recirc or sweeping to waste. I put the multiport valve into filter, runs for about 45 minutes then I see...

I have a Pentair Whisperflo 6 W/DE filter, top manifold. The Breather tube has a hole in the mesh cap. The manifold has a hairline crack. Could this be the cause of the high pressure? The pressure never goes pass 33psi. I cleaned the filter, found and replaced a cracked pump impeller...

Just bought a house with a pool, dont really know anything about this. The water is green, when the filter is off, it is at 40PSI, when on it goes up to 50-60 PSI, seems really high. I tryed to backwash but it still stays the same.
