Main Drain Cover Problem
Hi! Noticed that our Polaris 9300 robot might have gotten into a fight with our main drain cover. It's leaf season so we've been running the robot quite a bit. Our plan was to keep the pool open all winter so we don't have a swamp to look at from all our windows. Had a freeze-guard timer installed.
Googling and searching GW and TFP, I'm guessing the only way to fix the cover is either drain the pool or scuba gear or wait until next year? I cannot tell exactly what is wrong with the cover, it appears there is rust around the screw holes but I cannot be sure if the screws broke or if the robot just dislodged the cover. I presume fixing will entail installation of a VGB compliant cover if this one can't be screwed down again?
Thanks for any insight you all can provide.
