What I am mean is that under normal circumstances, per the builder, was to turn the skimmers off when vacuming.. That always got the flow gauge for the vac to the low end. For 3 years. Just tweaking the drain a little, not all the way to a 3rd would get it to the high side of the gauge...

All I am saying is that since this problem started occurring, if i hook the gauge up to the vacuum port, skimmers closed and the drain almost completely shut off will get it the gauge up to the low/mid point...
