I have an above ground pool that uses flexible hose (1 1/2-2", I think) to connect the skimmer to the pump and the filter to the return. I believe it is a lot longer than it needs to be. It hangs all the way to the ground and back up to the return on the filter side (about 3 feet), and the same on the pump side. I was thinking about replacing the flexible hose with PVC, since I plan on adding a liquidator in the near future. Any thoughts? Does the excess length of the current hose affect my pump efficiency in any way?
