Hello I have two skimmers going in that are Haywards. They have a 2" and 1.5" outlet. The 2" will be closest to the wall. Everything I have looked at shows only the outside hole going to the pump. I have a pump with 2" connections. I want to know will it matter if I plug the outside 1.5" hole and plumb the inside 2" to the pump? Or should I plumb the two skimmers using the outside 1.5" holes and tee the pipes to a 2" then run one line back to pump?
