I have an above ground pool. When I winterized I put a plastic cover over the skimmer box. So either that leaks or the gasket where skimmer box and pool connect. I’m not sure which leaks but now I have a huge icicle coming out of skimmer box. Do you think it’s gonna crack it ? I don’t think theirs anything I can do at this point . I’m really not sure so I hope you guys can help. Come summer should I put new gaskets ? Thanks for any and all advice
