So, if I'm understanding you the possible problem would be pressure and not GPM. The HW company only mentioned the GPM as a mis-match. How can I tell what the pressure should be for the filter and if the pump is within that range?
Also, any idea what the squeezed pipe could be caused by. The HW said the pump ran dry and it boiled the water and it melted the pipe. That pipe is bringing water from the pool. Between that pipe and the pump is the pumps screen filter. It doesn't make sense to me that nothing would happen to the screen filter (plastic) but would the plastic pipe.
Thanks,
Byron
