Should I flush my water heater annually?

Yes, you should flush your water heater annually to remove sediment buildup that reduces efficiency and shortens the tank's lifespan. This is especially important in Ottawa due to our moderately hard water, which contains minerals that settle at the bottom of the tank over time.

Sediment buildup causes several problems: it acts as insulation between the heating element and water, forcing your system to work harder and increasing energy costs. It also creates hot spots that can damage the tank lining and heating elements. In gas water heaters, sediment can cause rumbling or popping sounds as water bubbles up through the mineral layer.

The flushing process involves connecting a garden hose to the drain valve at the bottom of the tank and running water until it flows clear. However, this isn't always a simple DIY task. Older drain valves often become corroded or clogged with sediment, making them difficult to close properly after flushing. Many Ottawa homeowners discover their valve won't shut off completely, leading to ongoing leaks.

Professional maintenance is often the safer choice, especially for water heaters over 5 years old. Licensed plumbers can also inspect the anode rod (which should be replaced every 3-5 years), check for early signs of tank corrosion, and ensure all safety systems are functioning properly. In Ottawa's climate, proper water heater maintenance is crucial since heating costs are significant during our long winters.

Annual flushing can extend your water heater's life from 8-10 years to 12-15 years, making it a worthwhile investment. For a professional water heater inspection and flush, request a quote from Ottawa Pro Plumbing to ensure the job is done safely and completely.
