How Often Should You Change Your Sewage Ejector Pump?

Sewage ejector pumps play an important role in keeping the sewage system clean in homes that use septic systems. The dirty water and sewage is pumped either to the septic tank or to some other type of outside waste receptacle. The wear and tear from pumping sewage can wear these pumps out on a fairly regular basis.

Septic tanks are the recipients of the waste deposited by ejector pumps.


Just because you live in a home with a septic system does not necessarily mean you must have a sewage ejector pump. In many homes that have septic tanks, gravity removes the waste from the home. Pumps are typically used in homes where septic backup occurs regularly or where the sewage drainage system requires some additional help because the plumbing system has a non-standard configuration or requires special accommodations.


It is impossible to say exactly how long your sewage ejector pump should last because each home is different, as is its waste. These pumps are submerged in harsh environments that wear the pumps out quickly. Burnett Plumbing Company, of Grantsburg, Wisconsin, says you should expect your pump to last only a few years.


You probably should not try to replace your sewage ejector pump by yourself. Because these pumps are usually submerged in refuse full of bacteria, you may want to have a licensed and qualified professional replace the pump for you. Also, check to see whether the plumbing company can perform regular maintenance on your pump to keep it running longer.


If your sewage ejector pump fails, you need to replace it as soon as possible to avoid sewage back-up. If you have a water softener, this compounds the problem because when a water softener backs up through the floor drain it causes significant damage.
