Pump Pressure Dropped a little??

[rjg202]

My Pump pressure usually holds at a shaky 14 psi after a backwash and during running. I noticed today it is holding at a steady 10 psi. Should I be concerned I did backwash last week for quite some time but I think it was around 14. Pool is clear and I see no evidence of sand in bottom? Should this be reason for concern? Also my flow is extraordinary out of the aqualuminator, I really wonder if the 1.5 hp is too much, that was the package I got. I don't want to spend the money to downsize if I don't need to, no complaints about water thus far. I rarely backwash since my pressure holds steady with pea pebbles and zeobrite. I only backwashed because I had a lot of water due to storms, go figure had a hose pop off Saturday and I wound up using city water after dumping maybe 4-5 inches due to rain.

Thanks

Also my flow is extraordinary out of the aqualuminator,

Do you mean your outflow has increased and it coincided with the pressure drop?

Yes, seems my outflow is really high and I dropped about 3-4 lbs psi. I get a whilpool around my pool, so I have it pointed down about 135 degrees. It has always had a strong outflow, Saturday one of my hoses popped off, not sure what is up or just coincidence.

Based on that, I think you have somehow removed a restriction on the pressure side of your system. That could be many. many things so I wouldn't even guess as to what it was but, by removing that restriction, the water is now flowing at higher volume.

That's usually not a bad thing unless something has happened inside your filter but it sounds like everything is operating normally.

I would simply benchmark 10psi as my new clean pressure and then backwash when psi gets 25% above 10.

The extended backwashing may have dislodged some stuff that's been in your filter a while and it oculd have also redistributed the sand and allows better flow. That may have resulted in lower bed restriction and thusly lower filter pressure.
