Even if you maintain your sump pump carefully, you can still deal with unpleasant surprises. For example, if the pump stops working during heavy rains, your basement or crawlspace could get flooded.

Under these circumstances, you have two primary options:

  • Troubleshooting the sump pump
  • Using a portable water pump

We suggest the second option if you cannot start your sump pump in a short time. Leave the repairs for later and focus on minimizing water damage to your home.

What can cause a sump pump to malfunction?

Have you noticed how devices seem to malfunction precisely when you need them the most?

It could be a coincidence, or the device breaks due to intense use.

Either way, the first step towards solving the problem is understanding its cause. Here are the leading causes of sump pump malfunctions:

  • Power failure

A typical scenario is the sump pump not working after a power outage.

There are two possibilities here:

The power is still off, and the pump does not connect to an electricity source. In this case, consider a generator that you can activate manually. A generator is a good idea and a lifesaver in multiple situations. This piece of equipment will provide you with electricity whenever the power is off for any reason.

Or, the electricity is back, but the power surge has damaged the sump pump. Install a surge protection device to protect your entire electrical system to prevent this.

  • The sump pump is too small

An incorrectly sized sump pump will not be effective. If the pump is too small and you force it to work hard, you can damage it. Moreover, a small pump will not suck water out adequately.[1]

  • Installation issues

Not following installation instructions can result in a sump pump malfunction. For instance, manufacturers recommend a check valve to be installed on the discharge line. Without it, the pump impeller could start to rotate backward.

  • Shifting position

Sometimes a sump pump can shift its position inside the sump pit due to vibration. As a result, the float becomes ineffective, and the on/off switch does not work anymore.

  • Improper maintenance

Different manufacturers have different recommendations for maintaining their products. However, standard advice includes: running the pump annually, checking if water discharges, checking for unusual noises, etc.

  • Clogged discharge line

The sump pump will stop working if water cannot exit through the discharge line. Eliminate debris from the exit point and ensure the pipe is not at risk for freezing.

  • Product defect

Sometimes, a product can be defective from the beginning. Test the pump when installing it to ensure it is working correctly.

Sump pump troubleshooting tips

Your sump pump is not working, and the water level keeps growing at an alarming rate? Here are some fast sump pump troubleshooting ideas:

  • Check for power

Does the unit have access to power? Is it plugged in? Do you have electricity, or are you dealing with a power outage? You can plug another device into the sump pump’s outlet receptacle to ensure it gives off voltage.

  • Check the float switch.

Does the pump turn on when you manually lift the float? Look into the sump pit and check for objects jamming the switch.

  • Check the impeller

Sump pump clogged with mud is a widespread problem. If the pump sucks in dirt, the impeller can be stuck. Remove debris that could prevent the impeller from rotating.

Another possibility is having broken off impeller blades, which prevents them from moving water. Replacement is necessary.

  • Inspect the check valve

Sometimes a sump pump will run but without removing water. So the first action is to see if the arrow on the component is pointing in the right direction.

  • Inspect the discharge line

Check the pipe and its joints for leaks and repair them if necessary. If the discharge line prevents water from exiting, the water will return to the basin.

  • Check intake screen

Debris could have blocked the intake screen located on the bottom of the unit. Clean the screen to ensure the functionality of the sump pump.

How to reset a sump pump

A good old reset can do the trick for a variety of appliances. Sometimes you may not even know what was wrong, but who cares as long as you can do your job?

Keep on reading to find out how to reset a sump pump:

  • Disconnect power

Working with electrical gear requires precautions. Disconnecting power will ensure your safety during the resetting of any system.

  • Remove the pump from the sump pit

Remove the basin cover and disconnect drainage pipes. Place the pump on an old towel to prevent dirt from pouring on the floor.

  • Clean the sump pump from dirt and debris

Clean all the dirt collected in the bottom of the sump pit. Also, clean the pump’s filter. You want to avoid small rocks jamming your pump.

  • Check the drain line

Make sure the drain line is free of clogs, too. A clogged discharge line can cause your sump pump to make a lot of noise.

  • Reconnect the sump pump

Put everything back the way you found it. The instructions manual can help you if you can’t remember installation steps.

  • Press the reset button

Some pumps have a reset button, so press it to try and reset the motor.

The tips above are not working? Then your pump could have a more severe problem, and you need to take action to avoid a flooded basement. [2]

Sump pump maintenance tips

The reset process we described earlier includes some maintenance steps, but not all of them.

Do you want to keep your sump pump in good working order? You will need to complete the following actions regularly:

  • Examining the sump pump for rust and corrosion;
  • Cleaning the sump pump from debris and dirt;
  • Checking the instructions manual to see if the pump needs lubrication;
  • Testing the sump pump if it has not been working for a long time;
  • Checking for residual water inside the discharge line (it could freeze during winter);
  • Inspecting the check valve which prevents water from flowing back into the sump pit;
  • Ensuring a backup power source;
  • Making sure the discharge location is proper (20 feet from the house and allowing water to drain well);
  • Carrying out annual service on the pump by calling a professional. [3]

What to do if your basement is flooded and the sump pump is not working

Sump pump not working, basement flooding?

In many cases, homeowners cannot fix the sump pump in a short time. For this reason, you need to come up with a backup plan. Otherwise, you will be spending your day carrying buckets of water outside your home.

One solution is keeping a backup sump pump. Many homes have two sump pumps or even three. If one of the pumps fails, you can use the other one. Or you can use both of them for faster results in case of a flood.

The other solution is using a portable water pump.

This device is simply a pump that moves water from one place to another. Portable water pumps come in different types and sizes and come in handy for multiple jobs. They often have a high flow rate and are excellent for various thin fluids.

Keep a portable water pump in your basement. We guarantee you will find a variety of other uses for it!
