I've been building a gunite pool thinking that I can do this with all the info on this site and the web and so I began some time ago in this quest. My problem is when I received the skimmers, the instruction sheet noted that there was an auxiliary port on the skimmer but it didn't state to use this as an overflow. I know, you are all thinking what a dope (I've had that same thought many times).
So I didn't pipe for an overflow but now wish to have one. The concrete deck is poured but the tile isn't installed on the deck yet so I can cut the concrete and pipe into the drain line that I have for the trench drains. But I'm concerned that I may cut through the bonding wire as it runs right where the concrete needs to be removed. And I don't think the bonding wire is buried as it was attached to the wire mesh in this area. If I did cut the bonding wire, I could chip out the concrete and splice / reconnect with new lugs but I would prefer to keep the wire intact.
And another concern I have is will I be able to clean the pvc port on the skimmer well enough for the drain line to attach to the skimmer.
Is there anything available that has a sensor that can be installed in the skimmer and open an overflow valve at the pump area? Similar to the remote autofills (another item that I didn't install when I should have).
I thought about forgetting the overflow and just try to drain the pool manually but I live in Florida and we can get 3-4 inches of rain frequently. If I'm home, no problem but if not, then the pool overflows.
Does anyone have a solution?
