Re: Septic Pump problem: continually tripping the breaker it can be attributed to pump air-lock. between the pump and the check valve drains back into the sump. If the pipe between the pump and the check valve is solid, the air in the line can compress the next time the pump tries to empty the tank.

Also Know, will a sump pump trip a GFCI? Most sump pumps will not trip a GFCI circuit but it can if there are electrical problems with the pump or power surges.

Beside above, why does my sump pump keep tripping the GFCI?

The GFCI is tripping because the pump has a leak from the wet side to the dry side. Moisture is present in the motor, and causing current from the motor windings into the case. This current, instead of flowing through the neutral, now flows either through the ground wire, or worse, through the water and/or plumbing.

How do I know if my sump pump float switch is bad?

Damaged Float If the float gets punctured or split, water may leak inside the float and weigh it down. Fill the sump pump basin with water and watch the float. If it remains beneath the surface of the water, there is probably something wrong with the float itself and it will need to be replaced.

How do you adjust a sump pump float?

Pour several gallons of water from a bucket into the sump pump hole until it activates the sump pump. If it does not activate, adjust the float cord to make it tighter.

Power outages and surges can cause premature failure. Since you shouldn't use an extension cord with a sump pump, the best solution is a surge protector installed at the service panel for your home or putting it on its own surge protector that plugs directly into the outlet.

Why do motors trip GFCI?

A GFCI reacts to the imbalance between current going out and current coming back and does not detect the amount of power on any level. Your example, standing in water and getting a shock means current is going into the ground and not back to the Ground Fault device, so it trips.

Can you replace the float on a sump pump?
