"⭐⭐⭐⭐⭐ 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."

Water Heaters FAQs, answered by experts

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

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.

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.

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.
