I am a true Newbie and am learning a lot mainly online because the local "shops" are terribly unresponsive.
I have a large inground pool - 20ft X 40ft. Pool came with the "new house" First year was amazing but nothing but trouble since then it seems.
Last year it leaked - no - it almost drained itself mid winter - leak track or whatever they did showed no place it leaked from - no obvious ground wet spots and after refilling it - went all summer with no further issues. I attributed it to a possible main drain problem with the temperature extremes we had (below freezing then immediate warm up to full summer!)
This year - day before I was going to remove the cover - it lost 1.5 ft of water in 2 days. Called pool place and after a week and a half of no return call - I noticed it was not leaking as fast so I went for it and filled it back to mid skimmer level. By now of course it looked like a green marshy lake! After some turbo shock and salt it started to clear and then the problems began. The polaris pump died! Got one on order but decided to run the pool on recirculate to try to keep some of the algae down and noticed a leak - then a pour from the drain plug on my Sta Rite Cristal Flo Sand filter. No manner of loosening or tightening of the cap makes a difference. After some diagram research - wondering if the lateral drain is the culprit and how to fix that?? Really don't want to involve pool place if I can help it, they just called back about the leak that I had inquired about!!!! Afraid I may have to really get with on that since it did seem to leak some over the past two days, but I would hate to have them look at something I may be able to do myself!!
BTW - sand was replace 2 summers ago and did notice a little drip every once in a while, but nothing like the water pouring out now.
Also, should the water be leaking if on recirculate??
Any help for this newbie DIY'er is greatly appreciated!!!!!!!!
