If you live in an area where your basement frequently floods then you most likely have a sump pump installed. How do you know when to replace this essential item? There are a few issues to look for that tell you when you need to replace a sump pump. If your sump pump is making loud noises the entire time its running, either the impeller is bent or the motor is going out. To check for this, turn your unit over and remove the screen, using a screwdriver. If the impeller is bent, you must replace the unit. If your unit has stopped working completely, assure the power is running to it, also make sure the breaker hasn’t tripped in the panel box. Manually operate the float to see if you can get the pump working again. If the float is working, the motor is burned out and needs replaced. If your unit gets power, but still doesn’t work, it could have broken wires on the inside. Check voltage with a voltage meter if possible, electrical problems can be dangerous around water so use utmost caution. Most times, its more convenient and safe to replace your sump pump than to try to fix it.
