Water heaters have been common in Denver homes since before War World II. They are remarkably reliable and last about 10 years in the Denver area. If less hot water is coming out of faucets in your home, the water heater should be inspected immediately. A Bill Smith plumber will check the simple things first - pilot, thermostat, and water connections. The water heater will be fixed at a reasonable cost. Ten year old or older water heaters should be inspected annually because they are susceptible to tank and heating control failure. For more information about water heater replacement, click here.
