How often should water heaters be flushed and maintained according to the plumbing code?

Water heaters should be flushed and maintained annually to ensure their efficiency and longevity. This maintenance process involves draining the tank to remove sediment buildup, which can affect performance and lead to corrosion. By conducting this annual maintenance, homeowners can help prevent issues such as reduced hot water supply and potential leaks, thereby extending the lifespan of the water heater.

Additionally, regular maintenance is an important part of compliance with plumbing codes, which often stress the importance of appliance upkeep for safety and reliability in plumbing systems. This annual schedule allows for appropriate monitoring and servicing, ensuring that any problems can be addressed before they lead to significant damage or failure.

In contrast, more frequent flushing—such as monthly or quarterly—may not be necessary for most residential water heaters unless specific conditions warrant it, such as hard water issues. Waiting longer than a year can lead to a greater build-up of sediment and risk compromising the appliance's function and efficiency.
