Difference between Sump Pump and Ejector Pump:
Ejector pumps may look like a sump pump, but they have a very different function. These pumps are designed to handle both solid and liquid waste, and are most commonly found in finished basements. This waste, commonly referred to as “black water”, poses a greater health risk due to the presence of contaminants such as human waste. Flooding by black water poses a health risk and must be carefully cleaned.
Learn About Sump Pumps:
Sump pumps are often installed in a crawlspace or basement below the floor to defend your home against a flood or accumulating ground water. A sump pump also removes collected condensation created by your air conditioner and water from area-way drains, preventing moisture from collecting around the foundation of your home or in the floor of your basement.
As with any appliance or system, a little planning and regular maintenance is required to help ensure proper function
So if you notice that the sump pump in your basement or crawlspace isn’t kicking on when the water level rises, or if your pump is more than 10 years old — the typical lifespan of these machines — don’t wait to install a new one.
Here are the five things a professional should examine during an annual inspection of a sump pump:
- The alarm. Not all sump pumps have alarms that sound when the device is activated. If a sump pump has one, it should be tested to help ensure it functions.
- The check valve. A professional should make certain that there is a check valve on the discharge pipe. The check valve may help prevent water from flowing back down the discharge pipe after it is pumped out.
- A backup power source. Sump pumps often need to work during extreme weather conditions that may result in power outages. A professional may confirm there is a backup power source on a sump pump, such as a battery, and that it is working.
- The pit. A sump pump sits in a pit which gathers water until the pump removes it. The pit needs to be large enough — at least 24 inches deep and 18 inches wide — for the sump pump to function properly.
- The discharge location. The discharge location is recommended to be at least 20 feet from a home to help prevent water from draining onto neighboring properties, into public sewer systems or into a residential septic system.
Learn About Ejector Pumps:
Like sump pumps, ejector pumps have a basin installed under your basement floor. However, unlike sump basins, an ejector basin collects wastewater from the floor drain, washer, basement sinks, and below-grade bathrooms. The pump’s discharge pipe is connected to a sanitary sewer line. On ejector pumps where sewage is also handled, the lid to the basin is kept sealed and a vent pipe safely evacuates sewer gasses.
Whenever you flush a connected basement toilet or run a sink or washing machine, the ejector pump activates to help flush excess wastewater. There is also an additional alarm switch which senses and activates when a certain amount of solid waste accumulates. The pump then grinds up the waste and flushes it into the sewage lines.
Ejector pumps are often referred to as sewage pumps or sewage grinder pumps. They do not require regular maintenance, but may get clogged by large solid objects or fail to activate, causing a backup. In such cases, there is a chance of minor flooding. Black or grey water floods must be carefully cleaned due to the health risk, but are often on a smaller scale than groundwater floods. They are usually powered by a wall socket and lack a backup power system.
Common ejector pump issues include:
- Failure to activate.
- Clogs caused by large amounts of solid waste.
- Inability to activate during power outages due to the lack of a backup power source.
