Backstory: New homeowner w/ pool. Old school pool that had the main drain plumbed up into the skimmer and down the skimmer. Used a diverter back in the day. Looks like this diverter snapped off and they plugged the skimmer hole for the main drain line. Pool Boy that completed acid wash to open the pool advised that the main drain was not plugged in the deep end. My thought was that we would dig down find the main drain line and plumb a seperate line to the equipment. Took the time and effort to dig the ditch, dig the hole to find the main drain line - the day before we plumbed the new main drain I dived down into the deep end to uncover the main drain line and found that hole was also sealed. sealed with some heavy duty stuff that isnt going to be removed.
Now we had to create a secondary plan. Since the caretaker system had been 86'd. We found the two pop ups closest to the deep end and have plumbed them to be suction ports.
What do you guys think? I've been searching the interwebs and have not found any posts like this. I doubt I am a pioneer on this subject.
