Hi. Let me start off by saying I did a search, and seems lots of people have breakers tripping, but I'm not finding a similar situation.
We just moved into our house, and we had to have the pool brought back to life after x number of years of abandonment. It's our first pool. The pool is round and small-ish (21' dia, estimate is 6k gals). We had a pool guy come out, and he resurfaced the pool, put in a new (used) sand filter with new sand, and replaced the (unknown brand) 1/2hp pump with a Hayward 3/4HP pump, among other tasks.
The pump is plugged into a GFCI outlet outside, and then the circuit is protected by a 15amp breaker. The pump says it has a max draw of 10.1(?) amps. After the second day, we noticed the breaker was tripping. It would trip after a random amount of time, sometimes on start-up, sometimes after anywhere from 10 minutes to 2 hours of use.
My first thought was a bad GFCI outlet, so I replaced that. No go. Second was the breaker - replaced that and still no difference.
As the pool was just completely cleaned, and the pump is new, I'm discounting the possibility of a jammed impeller (although I haven't checked). To the best of my knowledge, the pump has not gotten wet. The skimmer basket and the basket at the pump are clear/debris free.
Unfortunately, we have not been able to contact the pool guy, as he has been on vacation. Does anyone have any idea of what I can be checking or looking for? I'm handy, and have a decent set of tools, so I'm not too fearful of digging in.
Thanks in advance!
