"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."

"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."

"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!!!"

"Nate Medford conducted our electrical inspection offered by the Awesome Club Membership Program. Nate didn't just inspect, he explained. He also didn't just explain, he corrected issues along the way. Today he brought our subpanel up to code and prevented a probable electrical fire. In addition, Nate spent lengthy time on the phone with me last week, giving clear guidance on LED fixtures to replace our florescent lighting. With Matthew's help, today the 6 light fixtures were replaced, a necessary wireless carbon detector and GFCI outlet installed, and for fun and convenience, 2 USB outlets given. Special note: the GFCI outlet wasn’t a simple swap-out. Nate had to cut into the trim for that installation, which he did incredibly cleanly and precisely. Upon completion, the work areas were cleared of trash and left in great condition. Thank you so much for all your work, your attention to detail, for caring."

"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

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.

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.
