Old pool construction question

[kgremillion]

My pool has something very similar to this. We think the pool was built in the late 60s or early 70s. We do have a main drain at the bottom of the pool that is plumbed separately<and leaking ;(>, but like you there is a fitting covering another pipe within the skimmer box. I don't know where it goes. We can't access our box from the deck though; we have to reach into the pool. I haven't been much of a help, but it is encouraging to find someone with a similar set up.

Thanks for the reply. I'll repost in the future when we remodel. I'm going to have to address finding out why the main drain isn't being used and adding more return lines. Only have one now. Also replacing that filter box with a new skimmer. Once the pool is drained we can start looking at the plumbing. I suspect that it still original under the pool. No idea what they used back then.. Iron pipe? The house plumbing is a combo or iron and copper pipe.

They used iron pipe and clay tile back then alot. Both of them are touchy, I have dug them up to find them imaculate, and also to find them to be garbage. It is a hit or miss thing, good luck.
