Good Day readers! 😄A common problem that many household customers face is corrosion with their water heaters. 😖 Not a problem for our Smartplumber Joey. After draining the waterlines and isolating the connector valves, Joey went straight to work. As seen in the before photo the 3/4" galvanized nipple piping had visible signs of rust where calcium and oxidation had accumulated over a few years. Joey replaced the nipple piping with a Heat Trap nipple. The purpose of the Heat Trap is to prevent humidity and heat from rising out of the water heater by convection. 😉 Tip: (Not needed on this job as an internal gasket was used.) Teflon tape is often overlooked by many DIY home users but when used helps free threads from debris, aids in lubrication, and prevents pipes from sticking if needed to be replaced several years later.
