I have a 30x15x5 15,000 gallon pool with a cartridge filter and 1.5hp pump. The pump produces adequate pressure when first turned on and will keep that pressure for a little while. However, it always drops down and ends up outputting a very low amount of water until I turn it off and turn it back on.
The inlet line becomes collapsed from what I assume is too much suction. Should I replace this line with some hard PVC piping?
