Water heaters with tanks are often faced with sediment accumulation-related problems and they’re often caused by minerals found in water that are transformed into solids at high temperatures. Sand and other particles from wells and municipal waters are also sources of sediment. They may be fine but those that don’t pass through the pipes will stay and settle at the bottom and will accumulate gradually.
What kind of issues can we expect when tanked water heaters have sediment inside, and how do you get rid of sediment in your water heater?
Problems caused by sediment in your water heater
- Water heaters often have decreased efficiency and reduced capacity when sediments are present. This is because the sediments can act as insulators and prevent the water heater from heating the water in the time that it’s supposed to heat. Sediments can also reduce the capacity of your tank because they can displace the water inside. This reduces the amount of water heater that you can use.
- Damage can also occur from sediment accumulation. One significant damage that they can cause is overheating. Because it takes a lot time to heat the water, your gas or electric-fired water heater may work itself beyond its usual performance due to the insulation provided by the sediments.
How do you prevent sediments from accumulating?
Flushing your tank once a year can help prevent sediments from accumulating. Before you flush your water heater tank, turn off the water heater’s circuit breaker or gas valve. When draining the tank, take the necessary precaution because you’re dealing with scalding hot water. Flush the water until the water runs clear then refill the tank with water before turning the gas or breaker again. Perform this maintenance task at least once a year to keep your water heater running in tip-top shape or you can ask an expert plumber to do it for you.
