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.
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.
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.
