I tried to close my pool tonight for the first time and ran into some problems. Several of my return faceplate Hayward model sp1408b were cracked and after putting my threaded plugs into these faceplate I saw bubbles. The bubbles eventually stopped after an hour or so but I'm assuming that is because the return lines filled with some water. Or do you think it could have just been releasing the air in the lines because I did shut the valves to create an error lock. The returns on my steps are different and have no screw holes and sealed just fine. All of my plugs have new o-rings and Teflon tape. Not sure if I should remove all plugs and replace faceplates or not. I'm thinking I should to be safe.
Although I'm honestly not sure how a new faceplate will be airtight either because the gasket sits behind the liner and I can't see that the faceplate will seal well enough against the fitting mounted in the wall itself since it seems like there should be some type of gasket between the faceplate and the liner. Thoughts? Thanks.
