We have a 9'18' Intex Ultraframe pool going on its 3rd summer. Last summer I changed out the factory inlets to 1/1/2" making it standard pipe. No leaks occurred and this worked great. However.
In tinkering with things I am wanting to change the drain plug (see attached photo of plug location) from the factory 3/4" Intex fitting to 1/1/2" wall fitting. Searching and reading I do not see where anyone has upgraded the small drain plug in a vinyl lined above ground pool. It looks common to add a main drain on the floor of a vinyl pool but not on the wall. Is this because of the static pressure on a 1/1/2" fitting at the bottom of a wall would not hold up and be a prone weak point to leaking?
I was going to use a fitting like the "wall drain" image attached and cut out the 3/4" existing drain. Then plumb this new fitting straight to the pump. I was also thinking of adding a large patch over the existing area to make the pool liner a tiny bit thicker and silicone all parts before I put them together. This pool is seasonal so it goes up in April and down in October.
