Should I replace my check valve?

[MinkyMomo]

My Pentair IntelliFlow pump draws 2400 watts at 3450 rpm (filter pressure = 14psi, having just cleaned the filter and reloaded with fiber media). That seems unusually high given the numbers posted by other users on this forum. It seems I have a garden-variety check valve installed, and I am wondering whether it would be worth it to replace with a proper Jandy or similar check valve to reduce head. I run my pump 6 hours daily at 2300 rpm...

Mom,

I suspect that check valve to to keep your spa from draining back into your pool when the pump is off.

It will not effect the operating speed for your pump.

I think that a filter pressure of 14 when running your pump at full speed, actually sounds on the low side to me.

I run at 1200 RPM most of the time, but I have no heater.. You should be able to run less than 2300 if you wanted.

Thanks,

Jim R.

Thank you, Jim. I've set the pump to 2000 rpm and seem to be getting a normal amount of spillover from the spa to the pool while drawing about 550 watts, with filter pressure of 8 psi... I'll leave the check valve alone.
