My pool has 1 1/2" piping to the main drain, pool return, spa drain and spa return. But the skimmer line is 2". In the pool shed the skimmer stays 2" all the way to the pump. But, the pump output to filter and all the return lines are 1 1/2".
now I want to re-plumb my pool shed to get rid of the globe valves and make the system simpler.
My question... Why is the skimmer line wider than the rest.
Also, is it a problem if I plumb 1 1/2" from the skimmer return to the pump. Basically, making the entire plumbing all the same.
