Water Heater Repair: Quick Fixes & When to Call a Pro

If your shower feels like an ice bath or you hear strange rumbling from the tank, it’s time to look at your water heater. Most issues are caused by sediment buildup, a faulty thermostat, or a broken heating element – all things you can spot without a toolbox. Before you panic, check the temperature setting, look for leaks, and listen for any unusual noises. These quick checks often point straight to the problem and save you a call‑out.

Common Water Heater Problems

Cold water at the tap usually means the tank isn’t heating enough. That can happen when sediment settles at the bottom and insulates the heating element. You’ll also notice water that’s orange or has a metallic taste – another sign of mineral buildup. A leaking water heater is serious; water around the base means a ruptured pressure valve or a cracked tank. Finally, if the pilot light keeps going out, the thermocouple is probably failing and needs replacement.

DIY Maintenance Steps

The most effective DIY task is flushing the tank. Turn off the power or gas, close the cold‑water inlet, attach a garden hose to the drain valve, and let the water run until it’s clear. This removes the sand‑like slime that reduces efficiency. If you prefer draining, open the drain valve and let the tank empty completely; then close it, refill, and you’re good to go. Checking the anode rod every 2‑3 years helps prevent corrosion – just unscrew it, inspect for wear, and replace if it’s more than ½ inch thick.

When you’ve tried flushing and the water is still lukewarm, the heating element is likely the culprit. For electric heaters, you can test resistance with a multimeter; a reading outside 10‑30 ohms means the element is bad. Gas models need a professional to inspect the burner and gas line, as improper handling can be dangerous.

If any of these steps feel risky, or if you notice rust, strange smells, or consistent low pressure, call a certified gas engineer.
