Hello, I am new to the forum, but have already learned so much. I would just like to thank everyone for all the help I have already received just from reading through other people's issues. I am new to pools; as many others, I became a pool owner and a home owner at the same time. Please forgive any ignorance on my part.
Attached is a photo of the plumbing setup for my pool. I have a 22,000 gallon inground vinyl liner pool, with a pentair whisperflo 3/4 hp pump, a DE filter, and in line chlorinator. As you can see from the photo, I have three suction lines (skimmer, main drain, and what I assume is a dedicated vac line on the wall of the pool). There are two discharge lines after the chlorinator, which both branch out to two lines before the pool for a total of four jets in the pool; two in the steps and two on the wall (the steps are paired and the wall jets are paired). Normally I have the three way valve set to split evenly between the two lines. My normal operating pressure is about 14-15 psi. With this setup, one of the two wall jets never really had any good flow (it happens to be the furthest line from the equipment). Recently I had an issue with an eyeball on one of the jets at the steps was stuck on, and when I tried to remove it, the fitting between the eyeball and the steps started spinning with the eyeball. I was able to remove the eyeball, and I retightened the fitting. Now, I suspect I may have a minor leak (which has been really hard to diagnose as we've had really hot days, so I can't tell if its evaporation and we've had a lot of rain also, so I can't let it keep going to see where it stops). Also, my pressure is now at about 8 psi split even, the same if I discharge just to the steps, but it shoots over 20 psi if I discharge just to the wall jets, and I finally get good flow at the one jet that never seems to. It also seems like there is less disturbance/cavitation in the pump basket when aligned to the wall jets vice the steps.
So my question is, is this just an alignment issue or do you think i have an issue/leak at the steps, or a clog at the wall jets? I recently backwashed, so the 8 psi is a fresh pressure.
Any help is greatly appreciated.
