"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

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.

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.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.
