"They took out a load bearing wall and installed a beam. I wanted to open up a room to open the kitchen. They were terrific, reliable, and I know it was done 100% right. I have not had any problems with it since and it has been 5 years."

Foundation Drain Installation FAQs, answered by experts

A sump pump will drain a flooded basement if it has a horsepower strong enough to remove the water faster than it is entering the room. If you have the wrong type or size of sump pump installed–or if your sump pump has failed–you may need to take additional steps to stop the flow of water or remove it manually.

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.

Installation typically takes 3-7 days, depending on the system and site conditions.

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.
