So I finally got all my plumbing issues fixed after reworking all of the valves and fittings on the suction side of the pump. The pool is running pretty well now but I am running into an issue where every day or two the breaker for the pump is tripping. I have been unable to identify anything in common with when the breaker trips. One behavior that I have found especially strange is when the breaker sometimes trips immediately on startup. Occasionally (maybe 1/4 of the time the breaker trips) it is when I manually turn the switch on, the breaker flips so quickly once you turn power on that if you weren't paying attention you wouldn't even hear the pump begin to start up.
I've recently replaced the timer (it was doing this before the replacement) and didn't see any obviously frayed or otherwise damaged wires that might be shorting. Is this a sign of an aging pump? It is a Hayward Super Pump and I honestly have no idea how old it is.
The pump is wired in as 115v and is rated for 18.6 amps at 115v, given the breaker is a 20 amp breaker maybe that 1.4 amp difference between the pump and breaker rating is sometimes exceeded due to an aging breaker? It wouldn't be the end of the world to re-wire the whole thing as its probably the closest thing in the whole house to a circuit breaker but I'd rather not waste a bunch of time and money if its something simple.
