Pumps going/gone bad or you have high resistance in your wiring somewhere. Or the breaker itself could be soft, that happens. I'd start with the breaker since that's easiest and you should have a spare anyway, they commonly do die.

Keep in mind that our boats use just ONE pump to service all the pressurized water faucets. It would be amazing if using one particular faucet caused the problem and not the others.

You could make sure the pump is cool to the touch, then have someone turn it on and run water while you monitor the temperature of the motor casing. It should not get hot at all unless you are running it a very long time or there is a problem.

Good luck.

[QUOTE=KnotDoneYet;18874]Searched and didn't find anything. Lately my water pressure breaker is tripping when using the water. We noticed it using the cockpit shower (nice anchor and swim day) but my daughter said the sink did it too.

Any thoughts?[/QUOTE]
