Hello everyone. I hope some one can help me with this. I have tried everything and nothing seems to work. I even called a pool guy and he didn't know what to do. He called me back 2 days later to tell me that another guy will run a pressure test and the cost will be $170.00 ( I cancelled the guy )
I have a pool with 1 MD, 1 skimmer and 2 returns. Everything was working perfectly fine until one day I start noticing a lot of bible coming from both returns. I have done everything. The presume is fine and the water run through the filtre with no air inútil we plus the machine info the skimer line; then it is a lot of air coming. The proble it is ONLY when the vacumme machine is conected.
