"My gas water heater was 12 yrs old and needed to be replaced. Since I had prior experience with Mr. Rooter installing a water filter under my sink, I felt confident that the job would be done professionally. Rohan and Derick did an excellent installation of the Water Heater. The office was excellent too in informing me of their arrival time. I high recommend Mr. Rooter."

Sump Pump Installation questions, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.
