What’s the Difference Between a Sump Pump and an Injector Pump?

We service hundreds of homes in Toronto every year and most homeowners aren’t sure what kind of water pump they have installed in their basement.  Here’s a little breakdown of the difference between a sump pump and an injector pump and how each is used.

Despite looking very similar and performing the same basic functions, a sump pump and an injector pump perform the same action very differently. Homeowners are often confused by what the difference is, and why you need one or the other. Sump pumps have been used in homes for a long time, but the injector pump still leaves people perplexed. Here, we will demystify these integral parts of a home water management system.

What is a Sump Pump?

The sump basin connects to a drain tile system, where water collected by the drainage system will flow to the sump basin. Groundwater is often collected into the basin, and helps to keep your basement dry. If the pump malfunctions or there is a sudden large rush of water, the basement will flood, but there are battery-operated back-up systems often available and used in conjunction to ensure dry conditions.

The sump basin holds the accumulating water until it rises to a certain height, high enough to activate the float switch on the sump pump. It will then pump the water out of the basin onto the lawn through strategic piping. It often arrives at a storm sewer, dry well, or other dispersal devices.

What is an Injector Pump?

Like the former, it is installed in a basin which is set into the ground. However, it does not utilize the drain tile systems to collect groundwater. Instead, it collects water from floor drains, such as excess water from a washing machine, sink, or even waste water from a bathroom, depending on the home and the quality of its systems.

Because an injector pump is used to handle this type of water, it has a sealed lid on the basin, and a vent pipe to discharge gases. If the injector pump will not come into contact with waste water, it will look the same minus the vent. An injector pumps is connected to a sanitary sewage line through a discharge pipe, very much like a home’s plumbing systems.

If an injector pump malfunctions, it will flood, but not nearly as heavily as if a sump pump fails. However, because this is tainted sewage water, it could create a health hazard if exposed to the dirty water and it must be cleaned up after properly.

If you would like to locate where the injector pump is located in your home, simply turn on the tap or flush your lower-level toilets. It should activate the pump.

Injector pumps are also often installed by plumbers, while sump pumps are often installed by basement waterproofing professionals, who offer a variety of long-lasting pumps and who are knowledgeable in basement water removal.

Mark Lipton - Homestars Review

Basement Waterproofing

Our basement leaked! Of course . . . we bought a 100 year old house! But my office needed to be in the basement permanently. I interviewed 10 different companies until we decided on the Steinbergs and their crew at Nu-Site! They are professional, reliable, courteous, honest, and they really make an effort to communicate with the client about every step of the process.

Sara Jack - Homestars Review

Foundation and Waterproofing Repairs

After several years of chronic leaks, we decided to have our basement waterproofed once and for all. The team over at Nusite was professional, answered my questions during the project and stayed within their quoted price....which is always a concern for me when working with contractors. Great job overall

Joshua Persaud - Yellowpages Review

Basement Waterproofing

Had several cracks in my basement wall and they would leak whenever we had a heavy rain. It started about a year and a half ago and seems to have gotten worse over the past 6 months. I tried having my neighbor seal it, but it started leaking again within a few weeks. Called several waterproofing companies and got several quotes. Finally went with Nusite contractors for the job. They gave a reasonable quote and I liked the guy that came by for the estimate. They stayed within budget and cleaned up before they left. It's been almost 3 months now and it seems to be working great.
