Why Flushing Your Commercial Water Heater Isn’t Optional—It’s Essential
If you manage a business that relies on consistent hot water—think hospitality, healthcare, food service, or multi-unit housing—you already know how critical your commercial water heater is to daily operations. But what you may not realize is how quickly that essential system can become compromised by one of the most common threats to performance: sediment buildup.
At The Stanley Louis Company, we’ve been servicing commercial water heaters since 1981. One of the most overlooked but vital services we provide is tank flushing—a simple maintenance task that delivers big results when it comes to extending the life of your equipment, maintaining energy efficiency, and preventing emergency breakdowns.
Here’s why flushing your commercial water heater should be a regular part of your maintenance plan.
The Problem with Sediment Buildup
All water contains minerals and impurities, including calcium, magnesium, and tiny particles of dirt or debris. Over time, these materials settle at the bottom of your water heater’s tank. If not flushed out regularly, they harden into thick layers of sediment that can cause serious damage to the system.
Common issues caused by sediment include:
- Decreased energy efficiency
- Inconsistent water temperatures
- Strange noises like popping or rumbling
- Increased wear on heating elements
- Premature tank failure or leaks
The harder your water, the faster sediment builds up. Businesses in Southern California often deal with moderate to hard water, making regular flushing even more important.
The Cost of Neglecting Maintenance
Ignoring sediment buildup doesn’t just lead to performance issues—it can cost you thousands in repairs or premature replacements. As sediment accumulates, your system has to work harder to heat the water, using more energy and increasing utility bills. In extreme cases, it can cause overheating, which damages internal components and shortens the system’s lifespan.
Worse still, neglecting flushing could void your manufacturer’s warranty—leaving you with no support if your water heater fails unexpectedly.
What Happens During a Professional Tank Flush?
When you schedule water heater maintenance with The Stanley Louis Company, our trained technicians perform a full inspection and controlled flush to remove built-up sediment. Here’s what the process typically involves:
- Powering down the unit and allowing it to cool
- Draining the tank fully
- Flushing with clean water or a descaling solution to dislodge stubborn sediment
- Inspecting components for wear or damage
- Reassembling and testing the system for optimal performance
The entire process is quick, non-invasive, and can often be completed with minimal disruption to your business.
How Often Should You Flush a Commercial Water Heater?
For most businesses, we recommend flushing at least once per year. However, facilities with high hot water usage or hard water may benefit from more frequent servicing. During your annual inspection, our team will assess your water quality, system age, and usage patterns to develop a custom maintenance schedule that fits your needs.
We also offer planned maintenance agreements to take the guesswork out of scheduling. Our technicians show up like clockwork, so you never miss a critical service window.
