When was the last time you thought about your water heater? If you’re like most homeowners, it’s probably only when the hot water runs out. But just like your car or HVAC system, your water heater needs regular maintenance to perform efficiently and avoid costly breakdowns.
At Mercy Plumbing, we’ve helped countless homeowners in Katy, TX avoid water heater disasters through routine inspections and maintenance. In this post, we’ll explain why maintaining your water heater is so important—and how it can save you money in the long run.
The Hidden Costs of a Neglected Water Heater
Ignoring your water heater can lead to a host of problems, including:
- Higher energy bills
- Reduced hot water supply
- Sediment buildup and corrosion
- Leaks or tank bursts
- Shortened lifespan
Many homeowners don’t realize that most of these issues are preventable with simple, regular upkeep.
How Maintenance Saves You Money
1. Improved Efficiency
Over time, sediment builds up at the bottom of your tank. This sediment acts like a barrier between the burner and the water, forcing your unit to work harder—and use more energy—to heat the same amount of water.
Result: Higher utility bills and more wear on the unit.
Mercy Plumbing Solution: We flush your tank to remove buildup, restoring efficiency and performance.
2. Longer Equipment Life
A well-maintained water heater can last 10–15 years or more. Without maintenance, you may face a premature breakdown and need a full replacement far earlier than expected.
Replacing a water heater can cost thousands. But a yearly checkup? Just a fraction of that.
3. Preventing Emergency Repairs
A failing water heater can burst or leak suddenly, causing flooding, mold, and property damage. Emergency repairs or replacements are always more expensive—and stressful—than routine maintenance.
Pro Tip: Schedule a water heater inspection before the holidays or colder months when demand is higher and downtime is more disruptive.

Tank vs. Tankless: Do Both Need Maintenance?
Yes—but the approach is different.
Tank Water Heaters
These store hot water in a large tank and are most vulnerable to sediment buildup. Annual flushing is essential.
Tankless Water Heaters
These heat water on demand and are more energy-efficient. However, they’re sensitive to hard water, which causes scaling and buildup inside the unit.
Mercy Plumbing performs descaling and flushing for tankless systems to keep the heat exchanger clean and extend the system’s life.

- Rumbling or banging noises
