"Marco reviewed the problem in detail. It was determined that locating the water main path approx 20' from the foundation, a splice could be made and repairs completed. That's exactly what they did. All in 3.5 hours. Awsome job."

"Jay immediately answered my inquiry and provided same-day service. He thoroughly explained what he was going to do and got the job done fast. His pricing was much better and service was faster than going through the big brand companies. I am incredibly satisfied and will be keeping Jay's card around for future plumbing repair needs."

"Rooter Guys installed a sump pump in my basement after we began experiencing flooding. They rearranged their schedule in order to fit us in sooner given the urgency of the project. They were professional, hardworking and kept us informed throughout the process."

"The company showed up when they said they would and completed the job within the time frame that they stated. Communication was a little rough with the field, but communication with the office was very responsive. Considering the extent of the work and the constraints within which they had to work, there was remarkably little collateral damage done. Unfortunately I was not able to witness the work before it was covered up and so I cannot comment on the quality of the installation, but can say that the company did a good job protecting the surrounding landscaped areas and seemed contentious and thoughtful in their approach to the work. I would definitely work with them again."

"Tyco is simply the BEST. A company and people who are genuinely good. I couldn't ask for a better or more honest plumber. Tyler is fantastic, and Rich and Mike are outstanding. Seriously, they're there when you need them and you never have to worry about if they're being honest. This is a company that values their customers and the relationships built. Tyco has done multiple jobs for us. They've installed a tankless water heater, cleaned out drains, fixed faucets, installed toilets, and more. Seriously, if you are reading this, you're in need of a plumber. Stop looking and just call Tyco. You'll never have to search for a plumber again. Thank you, Tyco!!"

Sump Pump Installation questions, answered by experts

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

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. 

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.
