Replace damaged flame detectors in HVAC equipment, such as furnaces and boilers, as well as some water heaters and ovens. These flame detectors work with a wide range of manufacturers since you can bend the rod and cut it to fit in your ignition system. However, you shouldn’t bend the rod without the included protective sleeve. Touching or marring the rod can damage its ability to accurately detect a flame.

Get ahead of your water heater maintenance—these traps catch debris from natural gas lines before it can enter the tank. Also called a drip leg, these traps are often required by building standards. They’re plated in zinc, so they’re mildly corrosion resistant.

Install them after your shutoff valve and as close to the water heater inlet as possible. To empty the trap, unscrew the cap and dispose of any debris.
