"⭐⭐⭐⭐⭐ Highly Recommend Northwest Plumbing! We had a great experience with Northwest Plumbing! They installed our new water heater and also took care of several plumbing repairs for us. They were professional, knowledgeable, dependable, and did an excellent job from start to finish. They took the time to make sure everything was done correctly, explained what needed to be repaired, and left everything clean when they were finished. It’s not always easy to find a company you feel confident calling again, but we absolutely would use Northwest Plumbing for any future plumbing needs. Excellent service, quality work, and a company we would definitely recommend!"

"The plumbing technician, Tyler Herriage, was able to arrive very quickly, inspect the damaged tile, bathroom faucets and pipes, water heater, and water meter, and determine that the water damage was not due to a leak this time. He was knowledgeable explaining the types and signs of leaks and I appreciated his honesty advising that there was not evidence a costly pressure test or camera run was needed."

"The first time I called it was Easter Sunday and we had a leak in our garage which we thought was the water heater. Rescue rooter came, it was not the water heater but a copper pipe behind the water heater. They removed the water heater, fix the copper pipe, and put the water heater back. The second time was for a leaking toilet. Both times they were punctual, texted when they were on their way, performed the work in a timely fashion and the technicians were great. Whenever we have a plumbing problem we will definitely call rescue rooter!"

Water Heaters FAQs, answered by experts

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 average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

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.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

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.
