How does the sump pump work?

Last Updated: 19th May, 2020

A sump pump is a small pump installed in the lowest part of a basement or crawlspace. Water flows into the sump pit through drains or by natural water migration through the soil. The sump pump's job is to pump the water out of the pit and away from the building so the basement or crawlspace stays dry.

Regarding this, how do I know if my sump pump is working?

The first way to test the sump pump is to trace the two electrical cords of the sump pump. The pump cord plugs into the back of the float cord plug. Both cords should be unplugged and only the pump cord should be plugged into the outlet. If a humming sound is heard when turning on the pump, the pump works.

Also Know, what triggers a sump pump? As water flows into the pit, it activates your sump pump by raising the pressure on the sensor, or simply raising the float valve (this is for automatic sump pumps, we'll cover manual pumps in a moment).

Likewise, do sump pumps turn on automatically?

The pipe usually has a one-way valve called a check valve at the pump end to keep the water from flowing back into the pit. Most sump pumps turn on automatically through a float activator arm or a pressure sensor. A buoyant ball floats on top of the water, manually moving the arm as the water level rises.

Can I pour water down my sump pump?

Pour a bucket of water into the sump pit Fill a five-gallon bucket with water and pour it slowly around the sump pump. The pump should kick on once the water level reaches a predetermined level below the basement floor.

How often should you test your sump pump?

Sump pumps require regular testing. How often you should test it varies depending on what your pump is used for. In most cases, sump pumps should be tested every three to four months. This should involve opening the inlet screen (often also called the pump screen) and cleaning it out, among other things.

How long should sump pump run?

A water table that is high can damage the slab even if the basement remains dry, so you may just need the sump pump to run every 8 minutes during your wet season, but if the above is true you are at least safe in a power outage. At least until somebody does something that alters the drainage.

Should there be water in the sump pump?

The water should not be that high in the sump. It should be down to around the 2-3" level inside. First, find the float switch which should turn your pump on when the water gets deep enough (it should be a ball floating in the water somewhere, maybe under the drain pipes).

Where does the water drain from a sump pump?

The sump pump is usually positioned in a hole in the basement floor (about the size of a beach ball), also known as the sump pit, and discharges the water. Depending on the home, the discharge water from the sump pit can be through a pipe in the wall of your home into the yard or to the storm sewer.

Is it OK for a sump pump to run constantly?

The most common cause of a sump pump system running continuously is when the sump pump float switch is stuck on the "on" position in your sump pit. This will cause it to run even when all water has been removed, which will burn out the pump prematurely.

Can you drain a washer into a sump pump?

When a washing machine or dishwasher is draining into a sump pump, the dirty water is forced through the sump pump and into your yard. This may cause the system to have trouble keeping up with the water, which means you may end up with water in your basement.

Will a sump pump keep basement dry?

Sump pumps don't do anything to prevent water from entering your house. It's no replacement for proper waterproofing in the form of a vapor barrier or sealant. It's part of the drainage system that leads water away. A sump pump also won't do anything about moisture buildup in the basement.

How often should a sump pump run in the winter?

It is quite normal for a sump pump in a 10-year-old home in our area to engage every day for several months of the year, but not normally in the dead of winter. The drainage system installed around the perimeter of your foundation will collect excess groundwater long after a rain or snowfall.

Why sump pump is needed?

A sump pump eliminates moisture and prevents flooding. Many homeowners' basements will flood at some point. Even if your basement doesn't flood, basement moisture can lead to mold and potential health problems. If you own a home and live in an area susceptible to excessive snow or rainfall, a sump pump is a smart bet.
