Discover the Water Heater Basics
Thermal expansion is the most common culprit of water heater failure.
Although water heaters usually run smoothly, they require regular care to ensure they remain in excellent shape. When they malfunction, they negatively affect the entire household and may lead to costly repairs.
This article discusses the basics of water heater maintenance and how to prevent long-term problems.
Maintenance for a healthy water heater
Before tinkering with the heater, read the owner's manual. It sometimes contains helpful info on ensuring it functions correctly.
Check for thermal expansion
Thermal expansion is the most common culprit of water heater failure. This issue typically affects homes with closed water supply systems where a one-way valve prevents water from returning to the city's supply.
Homeowners should inspect the tank twice a year and watch out for bulging at the top or bottom. Deformed relief lines and connections are also signs of early failure.
Switching to a thermal expansion tank is best to prolong the heater service life.
Check the burner
Homeowners shouldn't forget about the gas unit. First, find the heater burner and examine its appearance. If it's in order, it will be blue and feature yellow tips. However, an entirely yellow or sooty burner points to a potentially dangerous situation requiring professional assistance.
A reliable technician should perform biannual checkups to ensure the burner is functioning correctly.
Flush the water
Sediment buildup can degrade the unit's efficiency and result in corrosion. Therefore, homeowners should flush their heater twice a year. Those living in areas with hard water may need to clear the tank every few months. Homeowners who've never done this before may find the process challenging and should consider contacting an expert.
Test the valve
The pressure-relief valve can also alert homeowners of water heater trouble. If the numbers exceed 80 psi, installing a pressure-reducing model can optimize the system.
Testing the current valve is relatively straightforward. Lift the handle and allow it to close. Unless the valve lets out a spray of water into the drainpipe, it's time to replace it with a more efficient solution. It's also best to perform this test twice per year.
Professional service
A technician should service the water heater every two years, even if there aren't any noticeable issues. They'll extend the appliance's lifespan, prevent leaks, and reduce the risk of property damage.
Consider the water heater's age
Most models have a service life between 12 to 15 years, provided that the homeowner performs regular maintenance tasks.
Those unsure about their water heater's age can find the installation date on the manufacturer's label or "rating plate."
Replacing the water heater
If the heater's over 12 years old or leaking, there aren't many repairs a homeowner can do. So instead, it's best to replace the unit with a more efficient option to help reduce energy bills.
Get a professional opinion
Homeowners seeking to schedule a water heater inspection or invest in a new model should contact a trustworthy technician. They have the tools and experience to tackle any issue with ease and can recommend the most durable replacement options.
