When was the last time you flushed your water heater? If you’re like most homeowners, the answer is probably… never. While it may not be the most glamorous task, flushing your water heater is one of the easiest and most important maintenance steps you can take to keep your plumbing system running efficiently.
In this blog, we’ll cover how often you should flush your water heater, why it matters, the signs your system needs flushing, and how it can save you money in the long run.
Why Flushing Your Water Heater Is Important
Over time, minerals like calcium and magnesium—common in Florida’s hard water—begin to settle at the bottom of your water heater tank. This sediment buildup can cause several problems, including:
Reduced heating efficiency
Strange popping or rumbling noises
Shortened equipment lifespan
Cloudy or discolored hot water
Increased energy bills
Flushing the tank removes this buildup, allowing your water heater to run more efficiently and reliably.
How Often Should You Flush It?
For most homes, once per year is a good rule of thumb.
However, this can vary based on:
Water hardness: If your home has hard water (common in many parts of Florida), you may need to flush it every 6 months.
Water usage: Larger households with higher hot water demands may also benefit from more frequent flushing.
Type of heater: Tank-style water heaters require regular flushing, while tankless systems need descaling (similar process, different method).
Not sure how hard your water is? Top Notch Plumbing can help you test it and recommend a flushing schedule that fits your home’s needs.
Signs Your Water Heater Needs Flushing
Even if you’re not keeping track of the calendar, your water heater might be telling you it’s time to flush. Here are some common signs:
Your hot water runs out faster than it used to
You hear banging or rumbling from the tank
Water temperature is inconsistent
Water appears rusty or cloudy
Your energy bills are higher than usual
If you notice any of these issues, it’s a good idea to schedule a flush as soon as possible.
Can I Flush It Myself?
Yes—technically. Many homeowners choose to flush their water heaters on their own, and there are plenty of DIY guides online.
However, if you’re not comfortable handling water shutoff valves, dealing with sediment-heavy water, or operating around gas or electric systems, it’s best to call a professional. Incorrect flushing can damage the unit or void the manufacturer’s warranty.
