A well-maintained water heater lasts longer, runs more efficiently, and reduces energy costs. At Pinette Plumbing & Heating, we recommend annual maintenance to keep your system in top shape. Follow these expert-backed steps or let us handle it for you—just give us a call!

Essential Water Heater Maintenance Steps

1. Check the Temperature Setting

• Set the thermostat to 125°F for optimal efficiency and safety.

• Higher temperatures increase energy costs and risk of scalding.

2. Flush the Tank to Remove Sediment

• Turn off power/gas: Electric units—flip the breaker. Gas units—set the thermostat to "Pilot."

• Turn off cold water supply to the heater.

• Attach a hose to the drain valve at the bottom of the tank.

• Place the other end of the hose in a safe drain area outdoors or into sump pump pit.

• Open the drain valve and let water flush out until clear.(15-30 mins is ideal)

• Close the drain valve, remove the hose, and turn water & power back on.

 Pinette Tip: Hard water causes faster sediment buildup. If you hear popping or rumbling sounds, your tank may need flushing more than once a year.

3. Inspect the Anode Rod (Every 2-3 Years)

• The anode rod prevents corrosion inside the tank.

• If it’s corroded to less than ½ inch thick, replace it.

• Call Pinette Plumbing for professional anode rod replacement.

4. Test the Temperature & Pressure (T&P) Relief Valve

• Lift the T&P valve lever to release water.

• If no water comes out or it won’t stop dripping, replace it immediately.

5. Check for Leaks & Rust

• Rusty water? The tank could be corroding inside—call us for an inspection.

• Leaks around the base? Your water heater may need repair or replacement.

6. Ensure Proper Venting (Gas Water Heaters Only)

• Check the vent pipe for blockages or loose fittings.

• Smell gas? Shut off the gas valve and call Pinette Plumbing immediately.
