I'm flumoxxed. I have a old gunite inground pool. I have repaired the leak I had last summer and the pool holds water very nicely. It has not lost more than an appropriate 1 1/2 to 2" over the last 5 weeks due to evaporation here in Texas. My biggest issue besides being unemployed is that the stupid pool is getting air into the system. I bleed it off using the air bleed on top of my DE filter. I have done the following : Wrapped all the exposed suction side pipes and the valve with clingwrap and sealed that again with duct tape. I have soaped ALL of the other exposed pipes but found nothing.
I know that the big valve that determines Filter or Recirculate and Backwash does need a new gasket. I have a StaRite MaxFlow pump 1.6 and have replaced the stupid O ring on the glass lid twice in the last month ( The first time the guys gave me the wrong o ring ) the second o-ring seems to fit better but I am still seeing air in the glass ). My skimmers are always full of water.
There isn't a good leak detection company anywhere in my area. I say this because I paid bigtime for the only company to show up several years ago.. they insisted the problem ( big leaking ) was with my skimmer and then they proceeded to break the polaris connector. I had to fight to get them to repair that because they only detect leaks not fix them. The actual leak wasn't the skimmers at all but was with a pipe below the upper skimmer. It was replaced but the biggest leak was the pool light which we removed and filled. We went leak free for several more years until two years ago. We wound up replacing several pipes. This spring I discovered that one of the pipes that handled water coming into the pool had seperated from the side of the pool on the inside. I have now repaired that as of about 2 1/2 months ago.
I'm wondering.. can the glass lid have a leak ? or where else can I check ?
My husband is afraid it's a pressure crack in a line but again... we run the pump even in this less than optimal state bout 7 -8 hours a day.. surely we'd be losing water!
I'm taking ideas and suggestions. Thanks !
