Bulkhead fitting with a plug would be easiest.
Oooo thats nice!! Gumtree?
I would get a hole saw bigger then the pipe and remove that way, then attach a new bulkhead fitting, Id imagine you will want one at the least to act as a valve for easy water changes and having 2-3 more for returns and draining cant hurt
Quite cute how small that pool looks now lol.
i will be using bulkheads with ball valves etc for my plumbing/draining but i need to remove at least 8 of the current built in pipes as i want my bulkheads etc in different positions and sizes, there is also 4 extra large pipes at the rear as well near bottom i need to removeAwesome, makes that intex pool look tiny!
yeah will be a fun experience hopefully lol, the tank was originally a filter full of bio balls. I have never seen so many bio balls in my life the guy had to dig them all out and box them up in his garage and WOW just WOW lolWow this is going to be a fun project! What was the tank originally used for?
