"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

A journeyman plumber is a licensed plumber with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. Also known as a plumbing contractor, a master plumber is considered the highest level in this profession. In addition to passing all state-level requirements, master plumbers have several years of experience. They are allowed to lead teams, create blueprints, and design and install plumbing systems.

If you're connecting your gas line to appliances, the pro doing the work may recommend flexible corrugated stainless-steel tubing (CCST). Polyvinyl chloride (PVC) with high-density polyethylene (HDPE) is another relatively inexpensive material commonly used for residential pipes. Ultimately, you'll need to find out what is permitted based on the code requirements in your area.

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.

According to the U.S. Environmental Protection Agency (EPA), a leaky faucet that’s dripping at a rate of one drip per second can waste more than 3,000 gallons of water per year. This is one reason why it’s important to fix a leaky faucet sooner rather than later.

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.
