Both cables should be unplugged, and only the pump cord should be plugged into the outlet. If you hear a humming sound when turning on the pump, the pump works.
Can a sump pump burn out?
A common cause of sump pump failure is motor burn out.If the sump pump’s motor is too small, the water might be entering the basin or pit faster than the pump can pump it out. This can cause the system to run continuously, resulting in burnout.
How often should my sump pump run during rain?
In most cases, it’s perfectly normal for a sump pump to run constantly after heavy rain, often for 2 or 3 days in a row. Obviously, during periods of heavy rain, there’s a whole bunch of water falling on the surface of the ground very quickly, and that water has to go somewhere.

Do dry wells clog?
Dry wells can be susceptible to clogs coming from sediment, debris, and other blockages that come with runoff, which makes the dry well useless. As wastewater seeps out of the bottom of the pit any solids that do not dissolve will settle to the bottom, too, which prevents draining.
Are dry wells a bad idea?
If you were on a drywell, the debris would clog your stone and pipe. Water that daylights on top of the ground can evaporate and leach into the ground.
Where do I discharge my sump pump water?
The discharge point should be at least 10 feet away from your foundation, but 20 feet is better. Otherwise, the water will reabsorb into the soil, and your pump will need to remove it again.

What’s the difference between a wet and dry sump?
Wet sump systems store the oil in the pan but a dry sump system stores it in a separate tank and pumps the pan clean leaving it essentially dry. The usual set up for a dry sup system uses all but one of the stages to scavenge oil from the pan and the last stage is used to pump oil from the motor.
What are the three disadvantages of the wet sump system?

What causes a pump to run dry?
In the absence of liquid, dry running can occur in certain areas because of insufficient cooling and centring action. The consequences are overheating, abrasion, seizure of the materials, vibrations and other phenomena which may in due course lead to the complete disintegration of the pump.
