What Is A Sump Pump and Backup Sump Pump?

A sump pump is a simple machine designed to keep moisture and water out of a basement or crawl space in your home or business. They are recommended for property in low-lying areas prone to flooding. A sump pump simply pumps floodwater away from the building. There are two primary types of sump pumps available: a submersible and the pedestal pump. The difference is small, though: a submersible pump is enclosed in a waterproof case while a pedestal pump is kept out of the water. Pedestal pumps are generally less expensive but also much louder than submersible pumps.
A backup sump pump, as the name suggests, is a “plan B” and provides an extra layer of defense against flooding. They are usually battery or water-pressure powered, springing into action when the primary sump pump loses power during an outage. This is especially crucial considering the likelihood that a storm brings torrential rainfall as well as a power outage.

Rose Bernard

Red Bank, NJ

We had a plumbing emergency and found Mr. Rooter while frantically searching for a 24-hour plumber. We feel like we hit a gold mine. Not only did we get a timely response. Everyone at Mr. Rooter was friendly, professional, competent and went above and beyond. Our plumber, Phil, was extremely helpful and gave us tips we could use moving firwars. Not to mention, the cost was extremely reasonable.

Joseph Chis

Hillsborough, NJ

Had sewer water backup in toilet and tub. Received callback as promised and arrived early. The tech determined we needed the main line to be cleared. He quickly located the opening and had us cleared in minutes. Very happy with the service. I was not prepared for the fee but it was an emergency.

Christopher Cox

Little Silver Township

Plumber, Phil, came out on short notice on a Saturday night and fixed our issue quickly, professionally and courteously. I contacted a different, well known plumbing company right before Mr. Rooter. The receptionist was rude and they didn’t call me back to say they couldn’t make it until after Phil left! The Mr. Rooter receptionist was very nice and they called me back quickly. I’m glad they did.

I just wanted to say James did a great job at my house. Excellent service, professional and very nice. Thank you so much for helping me with my plumbing problem. Did wonderful job.

Rachel Turunen

Jackson Township

I was very happy that I went with Mr. Rooter’s. The service was very quick and up front. Jessie James was very helpful answering my questions and replacing my hot water heater. He was pleasurable to do business with. If another problem arises in my home, I will be using this company again.

William Holden

Brick Township, NJ

A thorough, professional, pleasant experience. I had a back-up in the 50 year-old pipes of my new home. I called Mr. Rooter to have them locate the blockage, snake the line, and then use their video snake to get a visual of the integrity of the pipes. I’m glad that I called and will use them again for future needs.

You get what you pay for. Edwin Robles of Central NJ educated me as a 1st time homebuyer on why and what he was repairing, prevention, PROMPT,(on a sunday at that!) clean, knowledgeable, super professional but DOWN TO EARTH and at a REASONABLE PRICE! Sewer pipes unclogged and main water line fixed. I was no longer crying once job was thoroughly executed. After all $#@* $tinks but somebody has to do it and I HIGHLY recommend him and this company for a job well done. THANK YOU VERY MUCH!!

Margie Rafferty-Criscione

Ocean Township

Absolutely lovely office staff! I always knew when the repair person was coming. Lorenzo our repair guy was awesome, I really don't think there is anything he can't do. He looks young, but don't let that fool you! So happy all the repairs are behind us. We really just did a one-stop shopping and decided to have everything we've put off fixed because it was such a tremendous experience!

How to Install a Backup Sump Pump

Installing Your Own Backup Sump Pump

As we mentioned earlier, a backup sump pump is power by a battery or water-pressure. A water-pressure powered device will have to be connected to your building’s water supply and will therefore require professional installation. But here is how to install your battery-powered backup sump pump:

  • Start by clearing out the workspace and cleaning your primary sump pump.
  • Install a check valve on the primary sump pump to prevent water from flowing back into the sump pit.
  • Tighten this check valve onto the side of the new backup pump to keep it secure and carefully set the backup sump pump into the sump pit.
  • Cut a 1.5-inch diameter PVC pipe to create the discharge pipe.
  • Glue the PVC pipe to the sump fittings and connect it to the original discharge pipe with a rubber connector and stainless-steel hose clamps.
  • Place the deep-cycle marine battery inside a protective box and onto a nearby shelf.
  • Connect the battery and the backup sump pump using a low-voltage connection.
  • Finally, plug the battery to an appropriate electrical outlet to charge.
