"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

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

While heat pump water heaters are more expensive than gas-powered water heaters, the ROI is higher for heat pump units. Not only are heat pump water heaters more energy efficient, meaning immediate savings on your energy bill, but they also last longer than traditional gas versions, meaning you won't have to buy them as often.

The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.

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.
