I removed a return eyeball that is an inpool chair last night. It always seemed off/misthreaded and was very difficult to remove but I screwed it back in. Pool company opened my pool, so looks like they misthreaded it. Well now I'm losing close to if not more than an inch of water per hour. Good news is I know exactly where it is. It's in the female threaded portion of that return, almost like it's cracked very close to the edge closest to the water. When I turn the pump off and remove the eyeball you can HEAR the water rushing out.
I'm desperately calling to have repair come out but are there any countermeasures? Shut off that return and cover with plastic grocery bags? I tried putting a winterizing plug but it simply won't threat right because of the cracked female portion. Tape bags over it somehow?
Any help would be much appreciated. Right now pump is off because I've got that winter plug in, there's two returns in the chair system - two chairs.
