"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"The plumber was very punctual and polite and did an excellent job. He made a couple of additional recommendations regarding our aging pipes and unsupported water heater overflow tank while he was here, but didn't push any services. He was also great when our giant, hyper dog got inquisitive and came over to say hi. The price was a little more than we were expecting, mostly because the awkward space he had to fit the sink into required some extra time and parts from his truck, but seemed to be in line with what we had seen while researching our plumbing options."

Water Heaters questions, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.

Replacing facilitates energy savings, decreases repair frequency, and aligns with modern safety regulations, maximizing safety.

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.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.
