Water Heater Maintenance: Keep Your Hot Water Safe and Efficient

If your shower feels lukewarm or your bills are climbing, it might be time to look at your water heater. Regular maintenance isn’t just for the pros – a few simple checks can prevent leaks, extend life, and keep your home safe.

Why Regular Maintenance Matters

Water heaters work under pressure and heat, so wear and tear happens fast. Sediment builds up at the bottom of the tank, reducing heating efficiency and causing noisy operation. A clogged pressure‑relief valve can turn a harmless fault into a dangerous burst. Skipping service also voids many warranties, leaving you to foot the bill for unexpected breakdowns.

When you keep up with maintenance, you get three clear benefits: lower energy bills, fewer emergency repairs, and a longer lifespan for the unit. In most cases a well‑maintained heater lasts 8‑12 years, while neglect can cut that in half.

Simple DIY Checks You Can Do

1. Turn off power and water. Before anything, switch off the electricity at the breaker (or gas supply if you have a gas heater) and shut the cold‑water intake valve. This prevents accidents while you work.

2. Flush the tank. Connect a garden hose to the drain valve at the bottom of the tank, place the other end in a safe drainage area, and open the valve. Let water run until it comes out clear – usually 5‑10 minutes. This clears out sediment that saps heat.

3. Inspect the anode rod. The rod attracts corrosion and protects the tank. If it’s more than 50% eaten away, replace it. A quick visual check can save you from a costly leak later.

4. Test the pressure‑relief valve. Lift the test lever; you should hear a burst of water. If nothing happens, the valve’s stuck and needs replacement.

5. Look for leaks. Check around the tank, the connections, and the bottom of the unit. Even a small drip can become a big problem if ignored.

6. Check the thermostat. Set the temperature to around 120°F (49°C). Higher settings waste energy and increase scald risk.

These tasks take about 30‑45 minutes and don’t require special tools. If anything feels out of scope – like a broken heating element or a corroded gas valve – call a certified gas engineer.

Scheduling a professional service once a year is still a smart move. A qualified engineer will clean the burner, inspect gas lines, and certify that everything meets safety regulations. It’s the safest way to keep the heater running smoothly.

Finally, remember to plan for seasonal changes. In winter, make sure the inlet water isn’t frozen and that the venting system is clear of debris. In summer, a quick visual check can catch early signs of wear before the next heating season rolls around.

By doing these simple checks and pairing them with an annual professional service, you’ll enjoy steady hot water, lower bills, and peace of mind that your water heater is safe for years to come.
