"I was out of the country for a few weeks and came home to a heavily leaking water heater. Went to the box store first and trusted my instinct to not have them 'send a guy'. i wanted a real licensed plumber to review this and am really glad I did. Mike came out the next day and had my new water heater installed before noon, plus answered my questions on several other projects. I highly recommend this company."

"They were professional, took a look at the catch basin and rodded it to get water flowing. Unfortunately the camera showed a lot of roots and the basin has a retainer wall issue. So more work is needed, however they didn't pressure me to do the work now, walked me through the different options to fix and only charged me for the original Angie's list deal to rodd the line. I would hire them again, and just may to do the other work."

"I coordinated the work with Mr. Rooter's home office. Unfortunately, they didn't relay to the technician that he needed certain materials to get the job done. This caused about a 60 minutes of extra time for the technician to search around for the part and then go pick it up. Other than that, the water heater gas control valve was successfully installed and I've got hot water again."

"Brian S did a great job diagnosing issues with my water heater. He was able to schedule one of their plumbers to come out and install a new water heater the next day. I would highly recommend Perma Seal for any future waterproofing and plumbing needs."

Water Heaters FAQs, answered by experts

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.
