Hi, I have been struggling getting my pool going this year. It has a bad algae bloom right now. I already dumped almost $100 worth of chemicals in it, but I was not able to defeat the algae bloom and it is back, so I will have to start all over.
The water is not flowing like it used to. It also had much air bubbles in the return. I found the intake threaded fitting going into the pump housing was leaking air, so I replaced it, hoping it would solved the issue(s). It did seem to take care of the air bubbles coming out of the return lines, but the water flow is still much weaker than it used to be. Also the pump basket is still not filling up with water, there is a lot of air in there. I have a new o-ring on the basket lid. The water level is where it should be, 1/2 way up skimmer. My first thought was a dirty filter, but even when I remove the filter and run with no filter at all the water flow is not any better. In fact, it is so bad, it will not even blow water out of the prime valve on the filter housing when I open it.
I am thinking it is either air still getting in somewhere else like the intake line. If so, I have no idea what to do. Or something going on with my pump and or pump housing. If it is the pump, I am thinking of getting a new dual speed any way to cut electric cost. My current pump is a Hayward SP3007x10AZ with a Super II 1hp. But I am not sure what to replace it with.
Please help with a plan of attack to get to the bottom of the issues!
I have a 15,000 gallon vinyl liner pool and a pentair filter cartridge. The pool is 5 years old.
BTW: I have never posted here but have lurked a long time and gained much valuable info. Thanks for your assistance.
