Top 3 Essential Maintenance Tasks from a Trusted Plumbing Company For Water Heaters

At Water Heaters Only, Inc., we know that regular water heater maintenance is the key to long-lasting performance and energy efficiency. Whether you’re scheduling annual service or need a same day water heater replacement, we are licensed water heater plumbers who are here to help.

1. Annual Flushing / Draining Your Water Heater

Flushing your water heater once a year helps prevent sediment from collecting at the bottom of the tank. Sediment buildup can reduce your water heater’s efficiency and shorten its lifespan.

Here’s why flushing matters:

• Removes built-up minerals and debris
• Helps your unit heat water faster and use less energy
• Reduces the risk of overheating or tank failure
  

If your home has hard water, consider flushing every 6 months. Even “self-cleaning” models benefit from occasional draining—those systems help, but don’t eliminate sediment entirely.

2. Water Heater Inspections

Routine inspections can catch small issues before they become big repairs. We recommend a quick visual check once a year—or anytime you suspect a problem.

Start at the top of the tank and work your way down:

For Gas Water Heaters:

• Check that cold and hot water lines are dry and free of leaks
• Inspect the overflow pipe connection for moisture
• Look at the vent pipe—make sure it’s:
  • Free of corrosion or soot buildup
  • Properly connected to the draft hood
  • Clear of debris that could block exhaust
• Verify earthquake straps are snug (required in California)
• Examine the gas line for:
  • Kinks or damage
  • Any strong gas odor (if present, leave the home and call the gas company)
• Look at the base of the tank for signs of rust, water pooling, or corrosion
• Ensure the air intake vents aren’t blocked by dust or clutter

For Electric Water Heaters:

• Check electrical wiring at the top of the unit
• Inspect thermostat covers for damage
• Look around the base for leaks or rust

Safety Reminder: Never store flammable items near your water heater—gas or electric.

3. Carbon Monoxide Detectors – A Life-Saving Essential

Carbon monoxide is a colorless, odorless gas that can be deadly if allowed to build up indoors. At Water Heaters Only, Inc., we always check your venting during inspections or a same day water heater replacement—but ongoing safety at home depends on a working CO (Carbon Monoxide) detector.

Why you need a carbon monoxide detector:

• Gas water heaters naturally produce CO during combustion
• A faulty or blocked vent could cause dangerous CO buildup indoors
• A CO detector is often the only warning you’ll get
  

Our recommendations:

• Install CO detectors (Carbon Monoxide Detectors) near any gas appliances
• Test the alarm regularly and replace batteries every 6–12 months
• Consider hardwired models for long-term safety
• Have a licensed water heater plumber check the vent system annually
  

A properly installed venting system is your first line of defense—but a detector is your safety net.

Most-Asked Questions About Flushing Water Heater

Q: Do I really need to flush my water heater?
A: Yes. It helps prevent sediment buildup, maintains energy efficiency, and may extend the life of your unit. Skipping this step won’t cause immediate failure, but over time it can lead to costly issues.

Q: I have a self-cleaning water heater. Does it still need maintenance?
A: Self-cleaning models help reduce sediment but don’t eliminate it. They swirl the water to keep particles suspended—but some sediment still settles. A quick flush is still worth doing annually.
