The air relief has no external leaks. This is only for manual operation correct? Nothing to do with normal ops? Gauge is good. Still puzzled that the only thing I did is remove that screen and pressure changes?

Yup, exactly. Time for new filters. But what is the screen in between the filters? That’s what affected the system from no pressure to high. Nothing else was messed with

Took this off and full pressure, actually too high now at 30psi. What does it do? Was a little dirty but have seen it worse over the years.

I should have full pressure on top of filter housing since it’s before the filters right?

Removed the motor/pump from housing and ran a thin screwdriver through all vanes of impeller

Yes, checked impeller for clogs. Cartridge filters. Filters just cleaned, but that always presents a high pressure condition when they’re dirty. Opening valve on top of filter housing is just a dribble of water.

Have a 20yo Pentair whisperflo that has almost zero pressure. Changed strainer oring. No difference switching valves. Impeller looks good. Poored water on valves and connections. All no change. Any ideas?

I just did a TSP clean on the filters; not new ones installed. These filters are only a year old; I usually get over 5 years on a set. Bought these off Amazon; probably got what I paid for..... So, flow is better, but not much, so I'm positive it's the filters now, as like you said, it's the...

Update. Got all the lines fixed. Started system back up and same pressure; 4 psi. Measured each leg of motor at 8 amps; all good there. So, removed all filters and started it back up; about 15 psi. A start! Inspected everything and found the o-ring at the bottom of filter "cross" that the...

Thanks all. As seen in pic, I removed the pressure line from pump to filter and it’s all clear. But, broke the coupling nut putting it back together, Grrrrr. So to HD later and then I’ll check amp draw on motor. It didn’t sound like it was slower or struggling. Also some pics of the system...

Yup, 4 psi constant; dropped from 20 psi. Flow also very low. Motor/pump sounds the same as it's always been. I do have ability to check voltage and amps, which will obviously give me watts.

Thanks, but I positioned all the manual suction valves shutting off/on the 3 different return lines; the floor drains, creepy floor cleaner and the skimmers. There wasn't 1 psi change. Not sure how to push water backwards on my system?

I was always taught to go back to your last work when a new problem is introduced and wondered about the filters too. But why wouldn't opening the pressure relief valve on top on the housing cause the pressure to instantly increase if there was a problem with them? That valve is basically...

I have an inground pool 15 years old. It has a 4 cartridge Pentair filter system with a Hayward pump and 1.5 HP single speed motor. Last Sunday I cleaned the filters, restarted it, and had excellent flow and pressure was around 20psi. Walked away and didn't pay attention to the pool until...

Really? Drain the pool? I'll check with CircuPool again, but when I gave them all the numbers, they didn't seem overly concerned.

CYA is right around 100. My pump is running 9 hours a day at 100% as is the generator. Just cleaned the cell this weekend and the entire system was just installed in April. I bought one step up for the size of my pool so it wouldn't have to run 100% (per company). I do see the gas coming off...

I don't, but the last time it was done it was high, but not excessive.

PH: 7.6 FC night: 1.8 FC morning: 1.2 CC: 0

OK, finally got one of the kits recommended for testing water. The generator will not generate enough chlorine for the pool without adding bleach to keep at acceptable levels. I did a FC overnight test as listed in the pool school and lost about .5ppm overnight, so if I understand correctly, I...

Just had my third 2hp motor go out over a 6 year period. The last was a locally rebuilt single speed motor that lasted barely 2 years. I'm considering a variable speed motor/pump combo like the Pentair Intellichoice VS3050, but they are definitely pricey compared to a $250 replacement motor...

I don't have the sheet in front of me, but I had the water professionally tested at a pool store and here's what I remember: CC & FC were less than 1 CYA was high, but not to where I need to drain Phosphates 500 PH 7.4 Salt 4200 How do I know if I have an algae problem? My cycle with...

New to this forum; buddy says it's great for getting info. My issue is with my new CircuPool SWG that I replaced my old Zodiac with. It won't generate chlorine at all. I have all the levels where they should be according to the company, but the techs at the company say my phosphates are too...
