I have a Pentair VS system with sand filter for a 21k inground pool with in floor cleaning. The in-floor runs 3-4 nozzels at a time. I also have rooftop solar.
Since the pool was new, if the VS is running full tilt (pool high or spa activated) my system pressure measured at the sand filter is about 30psi. This has always seemed high to me, but I don't know. I know all systems run at different pressures but does this seem out of the ordinary? I can always tell when my filter needs to be backwashed, because the spa therapy jets won't pull air anymore, at this point my system pressure is 35psi.
What are your thoughts?
