"Great company. We have used them for over 20 years and they have always performed well.  Recently, we installed carpet in our basement and this made the A/C condensation pipe too short.  We did not notice the situation at first but found out later that the water had soaked that area of carpet.  We went into a panic and called GAC.  They sent a tech out right away and solved the draining problem.  Always prompt and professional, one of best contractors that we have ever used."

"I've had Mahon at my house to fix big flood-scale plumbing disasters, and this time it was just a leak under our sink. They were great, and the plumber took the time to explain to us what was wrong, show it to us, and explain what needed to be done to fix it. These guys take care of us and we'll keep calling them in the future if we need a plumber!"

"BB&B removed a faulty garbage disposal and installed a new one. The plumber, at my request, purchased the new unit on my behalf and selected one appropriate for the job without gouging me on the price. The work was done quickly and neatly and I was quite satisfied; I will certainly call them in the future."

Small jobs welcome

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

Water Heaters questions, answered by experts

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.
