"I posted the plumbing need on Sunday late afternoon and almost immediately had a response from David at Mayan!! After a few texts and photo exchanges, we scheduled a time to connect on Monday. David was timely in arriving, reviewed the project scope and immediately got to work. Project was completed more quickly than I expected and David even solved another plumbing issue I was having -free of charge! Great work, great work ethic along with a personable, and professional manner. Would highly recommend David (Mayan Plumbing) to anyone with plumbing issues!"

"Ron wrote me a quote to replace a leaky interior 40 gal tank water heater with an exterior tankless water heater. After comparing with other quotes, we chose to go with Ron for several reasons, but mainly because of his years in the business, willingness to discuss concerns and answer questions, and his itemized quote. Ron kept me up to date with changes when the unit he ordered was delayed. He showed about 30 minutes early day of install to get a head start on some weather. During the install, he welcomed questions and explained everything to my satisfaction. We made modifications to the work, deciding not to do the sheetrock replace or electrical (contracted separately) and this was reflected in the quote. The work was timely and well done. He and his crew cleaned up well after. The price I paid him was under the estimate. I would use him again in the future."

Water Heaters FAQs, answered by experts

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.

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.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

Any item that can hold on to moisture and encourage mold growth should be discarded and replaced following water damage. Upholstered items, such as armchairs and couches, and soft items, such as mattresses, usually must be thrown away once they've taken on a lot of water. Soft furniture is difficult to dry out, creating an inviting environment for mold.

You may also need to replace hardwood furniture following water damage if you're unable to fully dry it out. If you have appliances and electronics that have been fully submerged in water, particularly sewage, you'll need to replace those, too.
