I have an Hayward 1hp SuperPump and it has been taking longer and longer to prime and "fire up" as the summer goes on. A couple months ago I would hear it click on, and then start pumping a few seconds later. If I turn it off and then back on it fires up quickly but now it takes 7-10 seconds to start pumping if it has been off for a few hours. Also, it often trips my GFCI circuit breaker before it has a chance to start pumping. Has anyone heard of this happening? The circuit trips even if it hasn't rained for days and everything appears perfectly dry. I am thinking I need a new pump. If so, does anyone have any recommendations? The current pump is 1 hp but I think I need 1.5hp for our 35-40k gallon pool. Possibly a variable speed depending on price and power savings.
Appreciate any advice in advance.
