    Sounds like the pump is too small. Or the filter is clogged. Or both.

    original pump was 3/4 and supplier gave new hayward 3/4 pump superflow. how can i tell if I have a blockcage in any of my lines. the circulation in the pool is fine , just notice my vacuume manual doesnt have the suction it used to have and I notice my pump is quite hot but not tripping breaker. Only when i shut off it kicks on after 5 or 7 mins . I know the the pump has a thermal overload , and when pump is cool enough it comes back on. So therefore am thinking maybe a block somewere

    What is your pressure reading? Can you post the information on the plate, particularly the SF or Service Factor?

    Not all 3/4 HP pumps are really the same HP as each other. Motor companies play this game where they label the same motor with different HP ratings for various marketing reasons. JohnT is asking about the SF, or service factor. The SFHP, which is SF * HP, is a better way to compare two motors.
