For anyone with a basement, a sump pump is a vital part of your home. It keeps your basement dry and saves you from flood damage-- - until it stops working. When your sump pump stops functioning, you'll need to repair or replace it.

Diagnosing the Problem

Before you do anything to your pump, you'll need to inspect it. Since your basement might be wet, you'll need to take some precautions when handling an electrical appliance. Wearing rubber boots will keep you safe from a possible electric shock when inspecting your sump pump.

If your sump pump stops working, you'll need to figure out the cause of its malfunction. Most of the time, a sump pump won't work because of one of the following reasons:
  • There is a problem with the check valve, which keeps water from flowing back into the pump.

  • There is a clog in the screen or the impeller.

TIP: While those are the two most common reasons, a sump pump that has stopped working might be the result of a dead outlet. Before taking the pump apart, try plugging the cord into another outlet to see if it works there.

Replacing the Check Valve

If the check valve isn't working properly, you'll need to replace it. Alternately, the valve may have been put in backwards. Either way, you'll need to remove the valve and replace it with a new one or put it in correctly.
  • If the valve is held in place by a metal coupling or adapter, you can loosen this with a screwdriver until it can be removed.

  • If the valve is glued or welded in, you'll need to cut the pipe itself and then add new piping in addition to the valve.

  • After putting in the new valve, or putting it incorrectly, you can secure it to the pipes the same way as before. Just make sure that the directional arrow on the valve is facing away from the pump.

Cleaning the Screen

If your sump pump isn't working due to a clog, you'll need to clean it out.
  • Separate the discharge pipe from the pump, and remove the pump from the container.

  • Carefully remove the filter housing from the rest of the pump by unsnapping it, or, if it is attached with a bolt, by using a wrench.

  • Once removed, you can rinse the screen with water to flush out the blockage. Additionally, inspect the impeller (the part that works to draw water in) for any blockages and remove them.
Put the pump back together and place it into its container.

If after replacing the valve, cleaning the screen, and making sure the outlet works, your sump pump is still dead, you will probably need to buy a new one. Though doing so might be an inconvenience, having a dry basement is well worth the trouble!
