Lake water pump trips breaker

Hello

I seem to be having a problem with my lake fed waterpump breaker tripping.
This only started happening today after taking a shower I reset the breaker and I can hear the water filling up again and the pressure works fine for roughly 2 to 5 minutes as I run the water..
The pump cycles between 50-65 pounds pressure..and then.. Pop.. Breaker goes and pressure drops to 0 again.. Reset the breaker.. And same same..

Any recommendations?… I was thinking I should get electrician to come in and replace the 20 amp breakers..

Thank you all in advance
Matt

Does the breaker feel hot when it trips? I don't suppose you have a clamp on amp meter?

Before changing any circuit breakers you need to check the current draw of the pump motor and compare it to the nameplate rating. More likely you have a bad bearing in either the pump or the motor that is requiring more horsepower from the motor.

If you have another breaker same amps and volts in the panel try swapping out as a test.

I'd also check the foot valve/strainer for obstructions like seaweed or frogs, or some human debris. I once tried selling a lake cottage that had an eel sucked up into the intake pipe . . . . and that made the pump work harder. Kinks in black poly pipe can cause trouble too.

Like an arm, leg or a few fingers?

I think those usually float, don't they ?

I was thinking more along the line of old fishing tackle, sandwich wrap, or lost garments . . . . but who knows ?

No.. we dump the bodies on the other side of the lake..

So.. playing around today as I wait for my Plumber to call ON $$$SUNDAY..

If I keep the water flow, lower.. the pump works fine.. no breaker trip.. if I put the thing on FULL throttle and water is flowing t very healthy rate.. She pops..
not sure if that helps in determining.. but I will ask him to measure current ..and I do have a spare dual 30mp to replace the 20 amp installed.. I hope its not the pump in the lake... ummmmm...I am not even sure where it is ...lol

Never replace a 20 amp breaker with a 30 amp breaker unless you want a fire.
