Let’s take a moment to talk about one the most important pieces of equipment in your home that is, more times than not, forgotten. The sump pump in your basement is a crucial piece of equipment that keeps your basement from flooding when heavy rains are coming down outside. The sump pump diverts water from your basement and foundation to a safer place where it can drain properly. Sump pumps have many moving parts and variables that make sure they run properly. If one of those variables goes bad, then the pump will fail.

4 Reasons Why a Sump Pump Can Fail:

1. Power Outage

A power outage is the most common reason for a sump pump failure. That is because sump pumps are not typically connected to their own power supply. They are most commonly connected to the home’s electrical system the same way lighting and the HVAC system is. Having a backup generator for your home in this case can be a lifesaver and prevent future headaches.

2. Sump Pump is the Wrong Size

Seeing this may make you think, “Let’s get the biggest pump so that it can handle any amount of water.” This thought can get you in trouble though, because sump pumps that are too big overwork and actually will wear out faster. While a pump that is too small will not be able to keep up with the waterflow that it encounters. The best course of action is to consult with a professional to make sure you have the proper sized sump pump.

3. Improper Installation

Installing a sump pump must be done exactly right. Manufacturer’s instructions must be followed carefully for the installation in order to avoid severe water damage down the road. Most manufacturers recommend or require a check valve to be installed on the discharge line. If not installed, the back-flow of water can cause the pump impeller to rotate backwards and unscrew off the motor shaft. In this scenario, you will still hear the pump motor running, but it would not be pumping any water.

Most manufacturers require the drilling of a small air relief hole in the discharge line between the pump and the check valve which is intended to prevent the pump from having to overcome the air pressure in the discharge pipe. The discharge pipe must be of the required diameter. 

Lastly, the sump pump pit should not be set in dirt or gravel. This causes debris to enter into your pump and can result in interference with the pump’s on/off switch or float arm.

4. Lack of Maintenance

Depending on the pump manufacturer, it is recommended that from every 2-3 months to once a year. To be safe, it is best if the pump is checked before rainy season starts. That way, you are not caught with a faulty pump when it is pouring down rain outside.

Like all equipment, a sump pump can also just unexplainably fail. This is the reason why preventative maintenance and routine checks are key so that you never get caught in a bad situation. Remember that even though a sump pump may seem expensive, but it doesn’t come close to comparing to how much a water damage can cost you both financially and emotionally after losing sentimental items.
