Avoid Cold Showers: Keep Your Water Heater Running Smoothly

Size Matters. So Does How You Use It

If your hot water runs out too quickly, then your water heater might simply be too small for your needs. Many homes are outfitted with a 40-gallon tank which works fine for a couple or small family. Throw in a few back-to-back showers and a load of laundry, however, and suddenly that tank is empty - and can take 30–60 minutes to reheat.

If you constantly run out of hot water, then talk to a plumber about upgrading to a larger tank or a tankless water heater. Tankless models will heat water on demand and never "run out." This is a great option for growing families or households with higher hot water needs.

Sediment Is a Silent Saboteur

Sediment and minerals in your water supply can settle at the bottom of your tank over time. This layer insulates the heating element from the water above and makes your heater less effective. You may notice lukewarm water, longer wait times, or clanking sounds from your tank.

A yearly tank flush can remove sediment and improve efficiency. It’s a simple part of routine plumbing maintenance, and a professional can handle it quickly. If it’s been years since your last flush - or you’ve never had one - then it's far past time to call in a plumber to investigate.

It Could Be Thermostat Trouble

Sometimes, the problem isn’t the heater but rather the settings. If the water never gets hot enough, then check the thermostat on your unit. It’s typically set between 120°F and 130°F. If it’s lower, then you might have found the reason for the chilly showers.

Adjust the thermostat to a safe and comfortable level. If it doesn’t respond or the water temperature still seems off, then the thermostat or heating element may need repair. A plumbing professional can diagnose the issue and perform a quick fix.

Water Heater Age and Wear

Water heaters are not built to last forever. Most tank models have a lifespan of 8 to 12 years. As they age, parts wear out and they become less efficient and effective. A unit near the end of its life might produce inconsistent temperatures, develop leaks, or just stop working one day.

If your unit is approaching its teens, then consider replacing it before it fails completely. A plumber from Mr. Rooter can help you explore your options. In any case, a proactive water heater replacement is better than waking up to a freezing-cold surprise or dealing with seemingly endless water heater repair.

Leaks and Pressure Problems

Leaks don’t just waste water; they also reduce the pressure available to move hot water through your pipes. A dripping tank, faulty pressure relief valve, or cracked pipe could be causing your hot water to fizzle out before it even reaches the faucet.

Get in the habit of inspecting your water heater. Keep an eye out for moisture around your tank or any changes in water pressure. If you'd like a professional inspection, then contact Mr. Rooter to request assistance.
