I am hoping some of the experts here have encountered this situation before and could provide some guidance. I have a pool+spa, and my spa has 2 drains in it. The drains are Hayward SP1153A's. The cover I am using is the replacement cover - Hayward WG1048E. I inherited this pool so am encountering this problem as I am opening the spa for the season (it was drained for the winter). Essentially, the screw tabs/ flanges that the drain cover attachs to with screws are broken off (see picture). There are no other tabs for me to drill/ screw into. I have contacted Hayward and they werent really able to provide any help other than to buy the same set of screws, but that wont work since the screw tabs are gone. Has anyone seen/ resolved this issue before? I am grateful for any and all assistance on how to best secure these covers.
