Water Heater Maintenance: Keep Your Hot Water Flowing

If your shower suddenly turns cold or you hear a loud rumble, it’s probably time to give your water heater some love. Regular maintenance isn’t a luxury – it’s what stops tiny problems from becoming costly repairs. Below you’ll find straight‑forward tips you can do yourself and clear signs that a professional should step in.

Why Regular Maintenance Matters

Think of your water heater like a car engine. Over time mineral deposits build up, parts wear out, and the thermostat can go haywire. When you ignore these issues, efficiency drops, energy bills rise, and you risk a leak that could flood your home. A quick flush of the tank once a year removes sediment and helps the heater heat water faster. It also reduces corrosion, extending the unit’s life by several years.

Another hidden culprit is the pressure‑relief valve. This safety device releases excess pressure; if it sticks, pressure can build and cause damage. Test it by lifting the lever – you should hear a short burst of water. If nothing happens, it’s time for a replacement.

Easy DIY Checks and When to Call a Pro

Start with the power source. For electric heaters, turn off the breaker and inspect the heating elements for obvious cracks or discoloration. For gas models, check the pilot light – it should be steady blue. A flickering or yellow flame signals a gas issue that needs a qualified technician.

Next, look for leaks around the tank, the inlet and outlet valves, and the drain plug. Small drips can become big messes fast. If you spot water pooling, tighten the connections or replace the worn gasket. If the leak persists, call a pro – it could be a corrosion problem that requires tank replacement.

Temperature setting is often overlooked. The ideal stay‑setting is around 120°F (49°C). Anything higher wastes energy and can cause scalding. Adjust the thermostat with a screwdriver, then monitor the water for a few days. If the water is still lukewarm, the thermostat may be faulty and should be swapped out by a professional.

Finally, listen for strange noises. A popping or rumbling sound usually means sediment is shifting inside the tank. Flushing the tank (see step one) often quiets it. If the noise continues after a flush, there may be a failing heating element or an internal leak – both need expert attention.

In a nutshell, a few simple actions each year keep your water heater efficient, safe, and cheap to run. Flush the tank, test the pressure valve, check for leaks, set the right temperature, and listen for odd sounds. When any of these steps point to a deeper problem, don’t DIY a fix you’re not comfortable with – call a qualified repair service. With regular care, you’ll enjoy hot showers and lower bills for years to come.
