Troubleshooting the basement sump pump in your home can save you time and money. A call to the plumber will be unnecessary if you can find out what is wrong on your own. Here are some things to look for.
A good indicator that your sump pump is not working properly is that you have standing water in your basement. Make sure you take precautions and wear rubber boots to avoid electrocution. The first thing you will want to check is to see if the pump is clogged. If this is not the case, plug in the pump and continue investigating.
There could be burned fuses in the fuse box. Making sure your hands are dry, check the box for tripped circuits. There could just be a simple fix of flipping the breaker back on.
Check to see if the float switch has been lodged somehow. The float switch is what turns the pump on, and if it cannot move then the pump will not operate. If that is not the problem there are a couple more things to check.
Check to see if the drain is clogged in the line by unlatching it from the pump. The way to see if it is the drain line is to turn the pump on while it is unattached and see if it starts working.
The Pump Screen
One last thing to check is the pump screen. Unplug the pump and feel underneath where the screen is. If there is debris there, it can be the culprit. Clear the debris and see if your basement sump pump will operate properly.
