"Mitch was great to deal with. He contacted me very quickly to discuss the issue with my water heater pilot light not staying lit. He fully explained his service over the phone and he came the next day. He contacted me to say he was running behind and he would be at my home 30 minutes later than expected. He was very friendly and professional. He thoroughly explained his actions while he diagnosed the problem. He answered any questions I had. He completed the job in a timely manner. The cost of the work was reasonable and fair. I would hire this company again."

"Not only did Jason do an awesome job replacing our leaking water heater, he was also extremely fast. He was done faster than we could even miss the temporarily missing hot water. Jason was also very punctual, both for our estimate and for the replacement. He also gave us multiple options to fit our budget so that was a great plus. Will be calling him again for the inevitable plumbing issues!"

"My central air quit during a nasty heat wave and they responded quicklyâ within a few hours a technician arrived that evening, followed shortly by the salesman when I decided to replace instead of repair. The job was scheduled for the very next morning! The installers were on time, friendly and cleaned up the areas. Everyone I dealt with was knowledgeable and professional. Interest-free financing was a huge selling point. Very good experience!."

"Kevan (spelled with an "a") was the only plumber who even called me back the day after Christmas. All these other companies that advertise 24/7 & Holidays emergency service did not even answer the phone. We lost power and our pipes froze in super cold weather we had Christmas 2022. In 32 years my pipes never froze but they did this time and they burst in multiple locations. Kevin called and came out the same day and worked into the night replacing multiple ruptures. He is extremely courteous and professional and I HIGHLY RECOMMEND HIM for any plumbing or water treatment needs. Ken H., New Paltz, NY."

Water Heaters FAQs, answered by experts

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.
