What is a Sewage Ejector Pump?

The water, waste, and sewage that leaves your home or business utilize simple gravity to move these unwanted materials from your property into the city’s municipal sewer system.  As you may be able to imagine certain utilities or plumbing features are not always going to be above the main sewer line.  When a toilet or washing machine is located at lower levels, a sewage ejector pump is necessary to pump the water and waste so it can flow through your piping system.  This helpful item also known as a pump-up ejector system is most commonly used in the lowest point of homes and businesses.  Although it is not necessary for every situation, normally when the sewer main line is located above the basement plumbing fixtures.  Ejector pumps are common in septic drain-field systems, perhaps in rural areas where the septic drainage field or holding tank might be raised substantially above the plumbing fixtures.

Sewage ejector pumps and plumbing


When compared to other modern plumbing technologies, such as instant water leak detection, these pumps are relatively simple in their design.  They are typically installed in a basin that is cut and dug into the ground.  This sump basin collects roughly 30 gallons of waste in the basin, this is the amount necessary for most homes.  A float is used to moderate levels and when a certain amount of storage is reached, the pump will be triggered to begin pumping the waste to the outside underground pipes.  The principle is similar to how a groundwater sump pump runs.  Instead of rainwater infiltration being drained of the house, it is waste/sewage being drained into the primary sewage system lines or septic field.  Not all local plumbing companies know how to properly install, maintain or repair these important systems.  When a sewage ejector pump breaks or fails it can lead to unsanitary conditions in the home, sewage being backed up, and even property damage due to leaking water or sewage.

At Plumbing Utah Heating & Air we have taken preventative measures to ensure that every sump pump installation is free from leaks and flooding.  All of our techncians install sump and sewage ejector pump sound alarms that provide audible warnings when levels are too high.  These devices come with a backup battery so that water levels can be monitored even if the power goes out.  If you are reading this outsite of Utah insist that your plumbers install monitors such as these to protect your home and business.

What can cause an ejector pump to fail

If you have read our online blogs before, you understand that we often discourage flushing anything down your toilet that is not meant to be flushed.  The most common reason that the pump will break is due to materials clogging the system.  Some toilet or drain clogs will be gradual and will take a while before things get bad enough that the pipe will no longer drain.  A clog with a sewage ejector pump can be immediate and extremely problematic.  This is one of the many reasons that everyone in your home understands that certain materials should never be flushed down the toilet.  This includes items like cotton swabs, dental floss, feminine hygiene products, disposable wipes, cigarette butts, and even chemical drain cleaners.  If you have a sewage ejector pump and are experiencing issues we invite you to call the professional plumbers at Plumbing Utah Heating & Air.  Our technicians are ready to dispatch to any home or business in and around Salt Lake City, contact us today at (801) 601-1298.
