I am getting ready to replace my flexible pipe with pvc in anticipation of adding the Liquidator. At present I have an ABG with the skimmer almost directly above the pump. It is a straight drop from the skimmer to the pump of about 3 feet. I remember reading somewhere that the Liquidator works best if there is a longer run from the skimmer to the pump. Is this correct? Should I run the PVC down the side of the pool before doubling back to the pump? I currently have 1.5 inch pipe on the suction and return. I plan on using 2.0 on the suction and 1.5 on the return - is this a good idea?
