1.5hp motor on a 19" sand filter - will it cause damage? Would like some advice.

Without knowing the particulars, it's hard to say. You could plumb a cheap ball valve in a line around the filter to partially bypass it. Just adjust the ball valve for a reasonable pressure on the filter.

Thank you John that sounds like it will be a great workaround for the time being.

Tell me if this would work as it is what I intend to do based on what you stated.

1 1/2" pipe from the pump split by a 45 degree "y" connector.
One pipe from the "y" running to the filter with a ball valve installed on that pipe.
The other pipe from the "y" I intend on running over the side of the pool and just have the water returning to the pool.

Does that sound correct? Sound like a plan?

Thanks again!

BTW I believe the pump I have is rated for 60gpm while the filter is only rated for 45gpm MAX. This method should still work correct?

You can either plumb the bypass back into the return line or straight into the pool. Whatever it takes to limit the water to the filter.
