"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

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.

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:

  • Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.

  • Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.

  • Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.

  • Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.

  • Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.

If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.
