"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

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.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

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.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.
