1) I have a leak in my solar plumbing fixed about a week ago.
2) removed a lot of leaves from skimmer basket and basket in filter plumbing (don't know the tech name).
I thought that my filter pressure has always been around 20 but I currently noticed that when the solar is not on the pressure is down to 12 or so and the motorpump makes a louder noise compared when the solar is on and the pressure is around 20-21.
can someone please give me some insight? Is this normal?
the pool water is nice n clear but I just want to know why the pressure changes..didn't notice this before.
