"Mr. Howell was punctual on the first visit to give an estimate for the job. He explained the charges clearly. An appointment was made for installation with the lady at the office for a much later date as the replacement faucet was not yet available. This appointment was rescheduled for an earlier time when the faucet arrived sooner than expected but Mr Howell did not show up for that appointment. Some internal miscommunication. Another appointment was made for the following week. He showed up on time for this one and installed the faucet in good time. The faucet being replaced had failed almost completely by then. The office staff is fantastic and very helpful. It was she that got my business since Mr Howell’s charges seemed a little high. The advice and assistance she gave me was worth the higher charges. However, I am not an expert on such things. The charges were explained up front. No fee was charged for the visit to give an estimate along with advice/confirmation of the type of faucet I would need."

"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."

Sump Pump Installation questions, answered by experts

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

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.

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.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.
