What are ejector pumps and when do you need one?

Ejector pumps are mechanical systems that move wastewater uphill when gravity drainage isn't possible. They're essential for basement bathrooms and other below-grade plumbing fixtures that sit lower than the main sewer line.

An ejector pump system consists of a sealed pit (usually fiberglass or plastic) that collects wastewater from basement fixtures, along with a pump that grinds up solids and forces the waste up to the main sewer line. The system activates automatically when wastewater reaches a certain level in the pit, then pumps everything up and out to connect with your home's main drainage system.

You need an ejector pump when installing plumbing below the main sewer line level. This is most common with basement bathrooms, wet bars, laundry rooms, or any situation where fixtures can't drain by gravity alone. In Ottawa's typical residential construction, basement floors often sit 6-8 feet below the main sewer connection, making ejector pumps necessary for any new basement bathroom installation.

The installation requires careful planning and permits. The pump pit must be properly sized and positioned, with adequate venting to prevent sewer gas buildup. In Ottawa, new basement bathroom installations require both plumbing and building permits, and the ejector pump system must meet Ontario Building Code requirements for sizing, venting, and electrical connections. The system needs a dedicated electrical circuit and GFCI protection.

Quality ejector pumps cost $800-2,000 for the unit alone, with total installation typically running $2,000-5,000 depending on the complexity of connecting to existing plumbing and electrical systems. Regular maintenance includes checking the pump operation and having the pit cleaned periodically to prevent clogs and odors.
