Most water heaters sold in the United States are tank-type, using either gas or electric heating elements. They are available in various sizes, with most residential water heaters available in 30, 40 or 50 gallon capacities. Proper maintenance of your water heater will not only extend the life of the appliance but provide an efficient and problem-free supply of hot water.
Water heater maintenance tips
- Keeping the thermostat at the medium setting will save energy and reduce sediment build-up. Sediment that builds up at the bottom of the tank makes it more difficult for the burner to heat water.
- Flushing the water heater every 6 months will extend the life of the heater and help reduce the number of sediment particles that reach plumbing fixtures, particularly faucet aerators and shower heads.
- Check plumbing pipes and fittings for leaks. Even a small leak (drip) will eventually rust the outside of the tank wall and cause the heater to fail.
- Refer to the water heater manual provided by the manufacturer. This will provide many troubleshooting tips for your particular model.
Water heater causing low pressure
If you are experiencing low pressure only on your hot water, you will need to check your water heater or have it serviced. Check the shut-off valve near the water heater to make sure it is not closed or partially closed.
Water heater causing water quality concern
Sand and/or light colored sediment may occur from calcium buildup in the water heater. Flushing the water heater will relieve the sediment.
White floating particles can be caused by a deteriorating water heater dip tube, and you should have your water heater serviced.
