Sediment sometimes looks like sand, but it is made up of minerals from your home’s water supply. These minerals don’t dissolve, and subsequently, turn into particles inside your unit. Unfortunately, this build-up can cause significant problems if left unchecked—costing you time and money by shortening the unit’s efficiency and functionality, and potentially causing the water heater to fail prematurely. In this video, This Old House plumbing and heating contractor Richard Trethewey explains how to drain and flush a water heater.

How to Tell if Your Water Heater Has Sediment Build-Up

There are a variety of indicators that your water heater has a sediment build-up including:

Draining a water heater is a relatively easy task that homeowners can tackle, but if the water doesn’t drain or the heater’s performance issues don’t improve after flushing the unit, a professional will be able to identify other potential problems that may not be recognizable to the homeowner.
