I have an 11,300 Gallon pool which has a Vac Line, Skimmer and Main drain. On the pad there are three different pipes coming in each with a shut off valve labelled "Vac", "Skimmer", "Main Drain".
I used the Flow Gauge that came with the Hayward Navigator and in order to set it between the "Min" and "Max" lines on that flow gauge, I have to run the vac line by itself. Otherwise, there is not enough suction. My sand filter was backwashed and shows 10-12psi, the lines are for sure not clogged, pump shows no air bubbles during operation. There just isn't enough juice to run both the skimmer and the Navigator at the same time. Isn't it suppose to work this way? Skimmer and Vac line together? If I try the Navigator doesn't move.
I really, really want to run both at the same time otherwise it defeats the purpose of having a dedicated vac line in the first place if I have to always shut off the skimmer to run it. What do I have to do in order to achieve this?
