"Elijah & Isiah were very professional, on time, completed the job quickly, & were competitive on their pricing. I am a local Real Estate Broker of 30 years & work with trades people in my industry regularly. Their level of plumbing knowledge is outstanding. Coming from the hard to impress homeowner, I would recommend them highly. I refer them to friends, family, & clients regularly. I would not hesitate to hire them again. Definitely 5 Star Plumbers!!!"

"Mitko was very proactive and helpful. I ended up replacing the water heater as well as correcting an existing plumbing mistake for my recirculating pump. He was quick and clean. The work was very neat and the price was reasonable. If you want a fast and smooth response, Mitko BG Plumbing is a good option. He was on time and responded to every call or text. HRE"

Plumbing FAQs, answered by experts

Yes, frozen underground pipes can burst. When water inside the pipe freezes, it expands, increasing pressure on the pipe walls. If the pressure becomes too great, it can cause the pipe to crack or burst, leading to significant water damage when the ice eventually thaws.

Plumbers start out at the apprentice level and then move up through the different levels of plumbers over their careers. After being an apprentice, plumbers move to journey-level and finally, plumbers who have met certain requirements for education and experience move up to master plumber. Most plumbers working on your home’s plumbing will be journey-level plumbers.

Yes, you can fix a shower diverter in many cases, depending on the specific problem. If hard water buildup is the issue, you can disassemble and clean your diverter. You may also be able to replace specific components when they break or wear down. All diverters are different, so when replacing parts, you’ll need to make sure you purchase a repair kit that’s compatible with your specific model. 

You should flush your water heater at least once a year, with some experts recommending a schedule of every six to 12 months (e.g., once in the spring and fall). The ideal frequency depends on several factors.

If your area has hard water with high mineral concentrations, you should flush the heater more often—typically every four to six months. Additionally, a water heater that is used frequently may require more frequent flushing than one that is used less often.

Regular flushing is important because it removes sediment buildup from the bottom of the tank. This maintenance helps improve the heater's efficiency, extend its lifespan, and prevent issues like clogs, overheating, and increased energy consumption. You can either learn to perform this task yourself or arrange for a service plan with a professional plumber.

You can pour bleach down the toilet as long as you dilute it since undiluted bleach can damage your toilet bowl. If you choose to use bleach to remove stains from your toilet, mix every cup of bleach with a gallon of water. You should also follow safety precautions when using bleach, like working in a well-ventilated area, wearing gloves, and never mixing it with any other cleaner.
