Water Heater Maintenance: Simple Steps for Reliable Hot Water

Got a water heater that sputters, makes noise, or takes forever to heat up? Most problems can be stopped before they start with a few easy checks. You don’t need a fancy toolbox – just a bucket, a wrench, and a little time.

Quick safety checklist

First things first: turn off the power or gas supply and shut the water valve. A quick safety step saves you from shocks or leaks while you work. If you’re dealing with an electric heater, flip the breaker. For a gas unit, turn the gas knob to the off position.

Once it’s safe, take a look at the pressure‑relief valve. Push the test lever – you should see a steady stream of water. If it drips or doesn’t move, the valve needs replacing. A faulty valve can cause pressure spikes that damage the tank.

Flushing the tank – the most important task

Mineral buildup is the silent killer of water heaters. To flush, attach a garden hose to the drain valve at the bottom of the tank and run it into a floor drain. Open the valve and let cold water flow until it runs clear. This removes sediment that makes the heater work harder and can shorten its life.

While the tank is empty, take a moment to inspect the anode rod. This metal stick eats away the rust before the tank does. If it’s more than half corroded, replace it. Swapping the rod is cheap and can add years to your heater’s life.

Next, check the heating element (for electric units). Remove the access panel, test the element with a multimeter, and look for obvious signs of wear. A bad element often shows up as intermittent hot water or a tripped breaker. If you spot a problem, swapping the element is usually straightforward.

Don’t forget the thermostat. Set it around 120°F (49°C) for comfort and efficiency. If the water feels too hot or not hot enough, the thermostat may be stuck. Turning the reset button on the thermostat can solve a sudden loss of hot water, but if it trips again, call a pro.

Finally, give the exterior a quick wipe down. Dust and debris can block venting on gas heaters or cause overheating on electric units. Clear any obstructions around the vent pipe and make sure the area stays dry.

Doing these checks once a year keeps the heater running smooth and avoids surprise cold showers. If you notice rust, strange noises, or water pooling around the base, it’s time to call an expert. Bridgewater Appliance Fixers can handle complex repairs, replace worn parts, or install a new, efficient unit.

Remember: regular maintenance saves money, cuts energy use, and keeps your family comfortable. Set a reminder for spring or fall, follow the steps above, and you’ll enjoy hot water without the hassle.
