I'm pretty new to the pool scene. My history is a little complex, I'll explain that at the bottom, for now here is my problem. My pool pump motor was replaced about a month ago and we are finally starting to see some progress (we can see the bottom of the shallow end) but today my pump started shutting off every 2 to 3 minutes, it will start up again after about 5 minutes. I have also notice that once it is running the pressure on the filter is about 5 psi it is usually around 15 psi. I checked the intakes basket on the side and it is clean. I have a bottom drain (which I can't see) but I was able to shut off the flow from the bottom incase there was a blockage but again that did nothing. When the pump is running the output seems pretty strong. It is about 78 degrees here but the pump is way to hot to touch. I had to use a towl when I took it apart to check the impeller for debris. There was some small stuff but nothing drastic and once I cleaned the impeller the problem still continued. Any thoughts on what my issue could be?
I am running C48L2N134C1 motor with a pentair cartridge filter, the vinyl pool is about 36,000 gallons.
We bought this place in July of 2013, the previous owner would not get the pool up and running fully during the purchase he said he hadn't used it in 2 years but everything is fine. We had a pool inspection during the purchasing process (May of 2013), the previous owner turned the pool equipment on while the inspector was there, the inspector said everything looked good and we just need to clean up the water. 2 months later after we close I took of the cover off and fired up the system. The filter broke immediately so I replaced it with a new pentair cartridge filter. The pool never cleared up the first year even with the pool stores help. I vacuumed a ton of gunk from the pool the first year. I gave up and winterized the pool in October of 2013. The next spring I started again this time I was able to get the pool to the point where I could see the bottom of the shallow end by mid June, then I went away for the weekend and came back to green soup. I never got the pool right the rest of the year, the pool store said my CYA was to high so they had me drain half of the pool and refill it. Still that did not fix the pool and I was forced to winterize it early in 2014 because I was going away for work. This year when I opened the pool the motor would not start, so I had to replace it. The motor was replace 4/27 and has been running great all month. I have CYA testing in a good range 30-40 compared to last year's 100+ range, the shallow end can be seen but we still have never seen the bottom of the deep end. Now today, the motor started overheating. I am getting pretty frustrated with the whole thing, any help would be greatly appreciated. I will take videos or pictures, just let me know what you need! Thanks!
