"I hired Bob's Plumbing, INC. with the installation of 2 toilets and a repair of a leaking faucet. They provided great communication and were punctual. Frank and Josh went above and beyond with an inspection of our water heaters for wear without even charging us. Also, they found a leak in our attic roof that we were not aware of! I highly recommend Bob's Plumbing and I will use them again!"

"I got 3 estimates to replace my entire A/C system along with the duct work. Chose Surgi's due to the good rating. I was not disappointed. From Art, the salesman, to the 2 installers and Craig the owner. They went above and beyond to make sure it was done on time, correctly, professionally and to my satisfaction."

Customers say: Quality work

"Matt was very friendly and knowledgeable. He did a great job and gave me good advice. With my basin, he did have to put a new faucet and the best lines and valves for each one. I also needed to have a new faucet installed in the kitchen. He also put new lines and valves in. I needed him to check out the dishwasher since no water gets inside it. It turned out it is the water pump. He did advise me to get a new one since getting it fixed would end up costing more. I have him due to have another project next month."

Water Heaters FAQs, answered by experts

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

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.

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 chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.
