"Fritz B. was my sales rep and he clearly knew what he was doing, including making a few minor recommendations that were in my financial interest. Easy to set up the scope of work. The grew was great, came in and did a great job, took about 6 hours. They even rerouted the exhaust flue for my hot water heater even though they did not replace the heater because the install guy Chris said "they did this dumb". Overall a great experience and I would recommend."

"This company is nothing other than excellent. A bit pricey, but you only get what you play for - and I got plenty. On Saturday afternoon, I found out that I needed a complete sewer line replacement. By late Sunday afternoon, I had one! The crew had to dig down about 10 feet to remove the broken line and then had to tunnel under my patio to get to the cast iron pipe in order to connect the new line. After the installation, the dirt was replaced, the area was seeded and covered with straw, and the sidewalks and parking lot were sprayed clean. Every single guy in the crew was friendly and knowledgeable. Special thanks to Gregg, Chris and Mike. I have recommended Mahon to friends and family and have already scheduled another job. If you need a good plumber, whether for something major or minor, I highly recommend Mahon Plumbing."

"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."

"I woke up this morning at 5am to my son calling me saying, "Dad Something is leaking downstairs", I walk downstairs to the furnace room to find the tank on the old non functioning Water Softener Spraying Water everywhere. I quickly shut off the water to avoid further damage. After many calls to various plumbers telling me they can Maybe get to me by Monday, which would leave my family with No Water for almost a week, Dave the Plumber came to my rescue. Not only did they get here within a couple of hours but the Technician Billy was Absolutely Amazing. He was able to quickly repair the problem and the price was great. Thank You So Much Dave the Plumber and Billy, You guys Made My Day."

Water Heaters questions, answered by experts

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.
