"As soon as I went on Angieâ s list they contacted me. He asked for pictures of our hot water heater and all the documentation on it. By the end of the day he sent me a quote for two different models. The night before he came to install the new heater he asked to see it to be sure he would have everything he needed. Mr. Rizzo is an excellent plumber and a pleasure to work with. He covered all the floors I would definitely recommend him. He was a rare find!"

"Jerry was and is a life saver..All the other companies, that came before him were just trying to only seek money and did not really care at all about the problem. Reliable plumbing and Heating really sticks by their name, and we now have Reliable Heating and Plumbing to do what ever work needed on our home for the rest of our lives. He explained all the work step by step and made us feel so comfortable. We can't thank him and his company for all the quality work performed. I want you to see the before and after pictures to judge for yourself."

"Excellent Plumbing was fantastic - he installed a new faucet, vanity, and water filter for me. Super punctual, really professional, very communicative, and paid close attention to detail. Everything's working great. What really stood out was Joe's dedication. He came back to check on the work and found an unrelated issue with my kitchen sink (which was already there). He gave me some great tips on how to fix it. I highly recommend Joe and Excellent Plumbing & Heating for any plumbing work. He's super skilled and has awesome customer service."

"Just Rite Heating & Cooling installed our central air conditioner today. The team of five were on time, courteous, friendly and hard workers. They laid down runners to keep the interior of my house clean. The boss, Eric, explained how each part of the system components worked. Together we worked out the placement of the ceiling registers in each room. After the system was completely installed I was instructed on the how the new thermostat controlled both the old heating system and the new air conditioning system. Best of all the installation was completed in one day!"

Water Heaters questions, answered by experts

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.

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.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

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.
