Sump Pump Installation questions, answered by experts

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

Repairs typically take 1-2 hours, while replacements, depending on accessibility, may require up to 4 hours.
