How Do Sump Pump Systems Work

The Basics of How Sump Pumps Work Pits beneath the structure collect water. If the water level reaches a certain point the sump pump automatically turns on and pumps the water out of the pit and away from the home’s foundation. How often your sump pump runs depends on the amount of moisture you have.

Are sump pumps supposed to run continuously?

A sump pump that runs constantly will wear out quickly and be more susceptible to malfunctions. If the pump continuously operates when there’s no water in the pit, it’s also more likely to overheat. Any type of sump pump failure leaves your basement vulnerable to flooding and extensive water damage.

Where does a sump pump drain into?

As water fills the basin—usually an 18-inch diameter pit excavated into the basement floor—a float switch actuates the pump and water is discharged through the sump pump drain line. The indoor span of drain line is usually a 1 1/4-inch or 1 1/2-inch PVC pipe.

How does water get into sump pump pit?

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. Today, sump pumps are common in new construction homes.

How often should a sump pump kick on?

Assuming your sump pump is in good normal operating condition, it should only run when the water level activates that float switch. Depending on your location, it’s not unusual for your pump to kick on two or three times a day.

How long should a sump pump run per cycle?

The pump runs for 10-15 seconds about every minute after a rain. In the picture you can see how much water is flowing in to the pit id say the rate is equivalent to a sink facuet at 1/2 to 3/4 open.

How long can a sump pump run without stopping?

Generally, sump pumps can run for six to 24 hours continuously, depending on how heavy the rainfall is and the quality of your pump. The aftermath of torrential rains or even flooding puts a higher demand on your sump pump to keep your home’s low areas dry.

Can I drain my sump pump into the street?

What does a sump pump connect to?

The pump is equipped with valves that sense escalating water levels or pressure. When the water gets too high, sump pumps automatically pump excess water out of the basement and away from your property using a discharge line. This line, called an effluent, connects the sump pump to a designated drainage area.

Should there be water in the sump pump pit?

Sump Pump Always Has Water First, it is usually completely normal that a sump pump pit has water in it, at least a little. If there is usually too much water, there is probably a problem, especially if you don’t ever hear your pump kick on.

Why does my sump pump hole keep filling up?

Sump pump and/or liner is too small or too big – The sump pump may just not be big enough to handle the job, so it runs continuously to keep up (see #1 above). Or the pump is powerful enough but the sump pit may be too small, causing it to fill up too fast and triggering the sump pump to work overtime.

Why does my sump pump keep turning on and off?

Why a Sump Pump Keeps Turning On and Off The float switch gets stuck in the “on” position. The float switch gets pinned to the side of the liner and can’t operate properly. The sump pump’s check valve may not be working properly or is broken.

Is it normal for sump pump to run every 30 seconds?

If your sump pump is running every 30 seconds, that could indicate that something is wrong. There could possibly be a fault in your basement foundation that is trapping water causing the pump to run every 30 seconds. If your sump pump is running every 30 seconds, it could also be due to a broken underground water main.

At what level should a sump pump turn on?

Level 1 is when your sump pump basically runs constantly, even when there is little to no rainfall. Level 2 is considered to be the “ideal” scenario, when your pump isn’t normally running — but does occasionally run when the need arises, such as during heavy rain or storm, and then shuts off.

Is it bad for a sump pump to short cycle?

Most of the time, it’s not something you need to worry about. Most sump pumps are sitting in a sump basin, so they collect the same amount of water every time. Now it is true that during one of these rain events a higher HP pump may run a few more cycles than a lower HP Pump.

Why does my sump pump runs every 5 minutes?

Periodic Heavy Moisture Periods Can Happen If your sump pump is running every minute but you have also been experiencing high levels of rainfall or other moisture, then the problem may just go away on its own. Record rainfall for example in your area may cause your sump pump to run frequently.

Why is my sump pump short cycling?

What Causes a Sump Pump to Short Cycle? In most cases, short cycling is a symptom of a fault in your pump’s float switch—a device which floats on the surface of the water in your sump basin and then turns your pump on when the water reaches a particular level.
