With the holiday season in full swing, having reliable hot water is more important than ever. After all, no one wants a chilly shower while it’s snowing outside. But your water heater is about to face higher demand. Between kids home for winter break, friends and family visiting, and extra holiday cooking, hot water use can quickly add up. This extra usage can strain your water heater, leading to premature wear or inconsistent hot water.
Luckily, routine water heater maintenance can help your system run efficiently and keep up with all of the showers, cooking, and holiday cleanup. In this blog, we’ll share simple DIY tips and explain which maintenance tasks are best handled by a professional—so your hot water is ready and steaming all season long.
Tanked Water Heaters: What You Need to Know
Before we get into maintenance tips, let’s take a quick look at how your water heater actually works.
Tanked water heaters store and heat a set amount of water in an insulated tank, typically 40–80 gallons. Once the tank’s hot water is used, it can take time to heat more. During busy periods—like back-to-back showers or holiday dishwashing—the tank may run out of hot water before it recovers.
Heavy use during these times puts extra strain on the tank and its components, which over time can lead to reduced efficiency, faster wear, and costly repairs.
Why Your Water Heater Needs Maintenance
Even a well-sized tanked water heater works hard every day, and that daily use takes a toll. Hard minerals in your water, worn protective parts inside the tank, and regular wear from showers, dishwashing, and cooking can all chip away at its efficiency over time. In the sections below, we’ll break down each factor and show what you can do to keep your water heater running reliably all year long.
Hard Water Damage: Minerals That Slow Things Down
In Southeast Idaho, including Rigby, the water is naturally hard, meaning it contains higher levels of calcium and magnesium. Over time, these minerals settle at the bottom of the tank as a layer of sediment. This buildup reduces heating efficiency, forces your system to work harder, and can even make it harder for protective components inside the tank to function properly.
Regular “flushing” of this sediment buildup helps keep mineral deposits under control and your water heating consistent.
Corrosion Risks: Protecting Your Tank
Tanked water heaters contain an anode rod—a long, corrosion-resistant metal rod, usually made of magnesium or aluminum, that sits inside the tank. Its job is to attract corrosive elements in the water, essentially “sacrificing” itself to protect the steel tank from rust. Over time, hard water and sediment can accelerate the rod’s wear. If the anode rod deteriorates or sediment builds up, the tank itself becomes vulnerable to corrosion. This can result in uneven heating, leaks, or—in extreme cases—a full tank rupture.
Regularly inspecting the anode rod and replacing it when necessary is key to keeping your water heater safe and prolonging its lifespan.
Everyday Wear: The Toll of Regular Use
Even under normal conditions, daily use puts stress on your water heater. Back-to-back showers, holiday meal prep, and frequent cleaning cycles gradually take a toll on the tank and its components. Over time, this can lead to reduced efficiency, uneven hot water, or leaks.
Regular maintenance—such as flushing sediment, inspecting the anode rod, and checking the system—can slow down this wear and tear. Staying on top of these tasks helps your water heater perform reliably, especially during periods of high demand.
Water Heater Maintenance 101—DIY vs. Professional
For tanked systems in Southeast Idaho, experts and manufacturers recommend both a full tank flush and an annual professional tune-up. The tank flush is something you can do yourself, but it is also included in a professional tanked water heater tune-up.
Here’s a breakdown so you know exactly what you can do yourself and when it’s best to call in a technician:
DIY Water Heater Maintenance Tips
While most major maintenance should be handled by a professional, there are a few simple, low-risk checks you can do at home to keep your water heater running smoothly during the busy holiday season. Of course, if you’d rather leave it to the experts, our expert plumbers at Advanced Home Services are happy to handle all maintenance for you.
Here are some ways you can care for your water heater:
- Check the Temperature Setting: Set your water heater to 120°F. This is safe, energy-efficient, and usually enough for showers, cooking, and cleaning. Adjusting the thermostat yourself ensures optimal performance without overworking the system.
- Inspect for Leaks and Corrosion: Look around the tank and nearby pipes for water leaks or rust. Small leaks may be visible or leave water stains. Catching them early lets you monitor the situation before it becomes a major issue.
- Test the Pressure Relief Valve: Lift the lever on the pressure relief valve and let it snap back to make sure it releases water as it should. If it doesn’t—or if it leaks afterward—call a professional to have it checked.
- Flush Sediment Buildup: Draining a few gallons from the tank via the drain valve helps reduce sediment buildup and maintain heating efficiency. For areas with hard water, doing this 1–2 times per year is recommended. This is something you can safely do yourself, but a full tank flush is more thorough and may be included in a professional tune-up.
Although these DIY steps can help your water heater stay efficient through the holidays, professional maintenance goes a step further. A trained technician can clean, test, and fine-tune components you can’t safely access on your own.
Maintenance Tasks Best Handled by a Professional
Some maintenance tasks require specialized tools and training. Attempting them yourself can lead to system damage—or personal injury.
That’s why expert plumbers are the best choice. At Advanced Home Services, our trained plumbers can safely handle pressurized water, gas, and electrical components. They can identify hidden issues before they turn into costly repairs and make sure your water heater is ready to handle heavy winter use.
When you book with Advanced Home Services, your water heater tune-up includes:
- Full Tank Flush and Deep Cleaning: We remove built-up sediment, clean the inside of your water heater, and make sure it heats water efficiently. This helps reduce wear and keeps your system working longer.
- Leak and Corrosion Check: We look for hidden leaks, early signs of rust, or worn parts like the anode rod. Catching problems early prevents costly repairs later.
- Heating Element and Thermostat Testing: Our team tests the heating elements and thermostat to make sure your water stays at the right temperature.
- System Tune-Up and Safety Check: We adjust your system and inspect safety features so your water heater runs smoothly and safely all year.
A professional water heater tune-up helps give your water heater a reset—restoring efficiency, preventing wear, and keeping your system ready for daily use.
Water Heater Maintenance Timeline
Not sure how often to maintain your water heater? Here’s an easy schedule to follow:
- DIY flush: 1–2 times per year (more often in areas with hard water)
- Professional tune-up: annually, which includes a full flush plus a complete inspection and any minor adjustments or part replacements
Following this schedule helps your water heater run efficiently, reduces the risk of unexpected breakdowns, and ensures your home has reliable hot water when it matters most.
Don’t let water heater issues disrupt your holiday plans. Regular maintenance is the best way to prevent breakdowns before they happen. No system is immune to wear, but routine checkups help stop small issues from turning into mid-winter breakdowns.
