"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"

Water main install, replace or repairs FAQs

Whether you need a permit depends on your local regulations. Always check with your municipality before beginning the installation. Most contractors will handle the permitting process for you.

If your backflow preventer fails, dangerous contaminants can enter your clean water supply, posing serious health risks. You may notice signs like visible leaks, a sudden drop in water pressure, slow drainage, unpleasant odors, or discolored water. If you experience any of these symptoms, contact a professional immediately.

Signs of a failing backflow preventer include visible leaks, a sudden drop in water pressure, sluggish drainage, unpleasant odors, and discolored water. If you notice any of these issues, it's important to have your system inspected by a professional.

You might need a backflow preventer if you have features like irrigation systems, pools, or other water elements that could contaminate your water supply. Commercial and industrial properties are required to have backflow preventers due to higher contamination risks.

A backflow preventer stops water in your main supply from reversing flow and contaminating clean water. A backwater valve is installed in your drainage system to block sewage from backing up during heavy rainfall or overflow. Both devices protect your home but serve different purposes.

The time it takes to install a backflow preventer depends on the type of system. A plumber can typically install a simple backflow preventer, like those for a garden hose or appliance, in less than an hour. Installing a backflow preventer for a complex system can take up to a full day.
