I have a 20.6" x 42.6" pool that has one skimmer, one main drain and two returns. There is a third pipe run that used to be for some cleaner or something but it is currently closed off. I was thinking about making this another return and piping it into the existing returns. This will be really easy as it is right next to it.
I have no use for it otherwise, is there any benefit to this?
Otherwise, I was just going to cut the pipe by the filter side and cap it below ground.
