"Josh was very responsive to our questions and very knowledgeable, telling us various options for installation. He was flexible on our schedule, needing HOA approval for the exterior changes. The price was certainly reasonable. We chose a sump radon mitigation system. He even painted the piping to match the exterior--one less worry for us. The install looks great. We are going to finish our basement, and he made sure to install it so it would not interfere with the finish. It went from 4.1 (just above the standard requiring mitigation), to an average of 0.68!! (Just outside air measures at a 0.4!) We are thrilled and definitely recommend his team. My concerns for my familys health are definitely relieved. Thanks, Josh!"

"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."

"We heard a constant hum from the sump pump last evening and found the motor trying to run but nothing being pumped out. We pulled the plug and called for service. Joe found nothing wrong with the pump. A switch was turned off that should have been on and the outside drainpipe was frozen solid. We had not thought of the drainpipe as we knew the water pumped out a few days before as snow was melting. An unusually long cold spell caused freezing and pitch of the pipe was wrong at the end of the pipe. Joe was very knowledgeable and honest. He got things working again and gave us good information for the future. We will definitely use this business for future plumbing needs. We would recommend them to others. We felt the service fee was reasonable too."

"I needed a sump pump repair and received two quotes. Bulletproof Plumbing and Heating was cheaper by a couple of hundred dollars. They successfully performed the work as promised and I was impressed with the quality and customer service experience that I had Todd (the owner) quote another project to install new plumbing on a basement kitchenette we were installing. Again his quote was significantly lower than another quote I received and the end result was another quality project completed by his team. Since then I have used Todd and his team for a couple of other plumbing issues. He is very responsive to my texts/calls and it is comforting to know that he will always send the same plumber (Jesse) to address our issues. It is also nice to know that I can always count on Todd 24/7 to respond back to me and treat me as though I was his most important customer. His company is definitely is worth hiring to address your plumbing needs!!!"

"Found Denver Drain (DD) through Angie list and being an old salesman myself, I reached out to the first company that left a message; that was Jeanette from DD. They could have had someone out the next day, but to accommodate my schedule he was here in 3 days. JJ was professional, courteous, and respectful, and got the job done quickly. I highly recommend DD to anyone and they are now in my contact list as my plumber MW"

"Keith was excellent from his first visit to explain what needed to be done on the kitchen drain. Afterwards, I requested a new water heater to be installed. Both were done this morning in a timely manner. Keith is very competent, takes the time to explain everything, and did an excellent job. I also was extremely thankful to Keith this morning as he identified a gas leak that I otherwise would not have known about. Because of Keith I was able to call the gas company and they came out within the hour to address the problem. I highly recommend Keith to anyone needing services. And, if I have any future issues, Keith will be the first person that I will call. He is a wonderful person, and he did an excellent job for me! Thank you Keith!!!"

Sump Pump Installation FAQs, answered by experts

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

You shouldn’t shower while a sump pump isn’t working. Although household wastewater isn’t supposed to go into the sump pit, it’s best to wait to shower until your sump pump is running properly and able to move excess water out of the basement. If you need to shower when the sump pump isn’t working, aim for a short shower.

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.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.
