Charlotte Home Inspector water heater maintenance.wmv
www.homeinspectioncarolina.com The typical water heater in Charlotte NC is usually a cylindrical tank with a heat source in or below the tank, used to heat entering cold water for supply of hot water to a home when needed. Most residential water heaters have a 40 to 50 gallon glass-lined steel tank (but can range up to 88 gallons). The heat source can be either gas (natural or propane), oil, electricity, solar or geothermal. The life expectancy of the average water heater is 8 to 12 years for gas and oil, 10-15 for electrical, solar and geothermal, and over 20 years on tankless (made of stainless steel). There are several different types of hot water systems used in the Charlotte NC, Gastonia NC, Weddington NC, Huntersville NC, Indian Trail NC including: Indirect water heater systems, dual purpose water heater systems, on-demand water heater systems (or tankless), high efficiency gas systems or direct vent systems.

Dual purpose water heaters (also referred to as hedonic water heaters) use one of the heat types above and then store domestic hot water while circulating hot water through a heat exchanger connected to a forced air furnace.

So, you don’t have to turn off the gas first? Guess the steps are: 1) turn off water supply/feed at top of tank, 2) drain water through hose running outside of garage, 3) turn water back ON? But leaving the gas one is okay?
cool video! I had a problem where my pilot light would not stay on. I fixed it for about 6 bucks.
i also made a video on how to fix your pilot light.
its in my profile.
would u really even have 2 turn the water off? all ur doin is draining sediment from the bottom, right?
Those plastic drain bibs won’t seal if you allow hot water to pass through it. He will be lucky if the drain bib sealed when he closed it.
I shut them down and then drain water from a sink until it is cold. Then I drain the tank and then partialy fill and drain the tank several times until no more sediment or slime comes out. I will sometimes replace the plastic drain bib with a brass one. Dont neglect the burner and flue.
Most gas H2O heaters are not vented correctly. Check GAMA tables.
Thanks for the video- very informative. How long do you let it drain? Did you have to power it off @ the breaker before you started working on it?
