As cooler fall weather sets in, Tacoma families lean on their water heaters more than ever—longer showers, warm baths, and constant loads of laundry mean your system is working overtime. September is the perfect time to schedule water heater service in Tacoma before the heavy demands of winter. Servicing your system now keeps hot water flowing when you need it most and helps prevent costly breakdowns later.
In this guide, you’ll learn why early fall is ideal for water heater maintenance, the benefits of annual flushing, signs your system may need repairs, and how Tacoma homeowners can extend the life of traditional and tankless units.
Why September Is Ideal for Water Heater Maintenance
Waiting until winter to address water heater issues is a gamble. Cold temperatures put added stress on your plumbing system, making any underlying problems worse. By scheduling service in September, you:
- Prevent winter breakdowns – Catch small problems before they turn into no-hot-water emergencies.
- Improve efficiency – Clean and tuned systems use less energy, saving money on utility bills.
- Extend equipment lifespan – Routine care can add years to the life of your water heater.
- Enjoy peace of mind – No worrying about surprise failures during the holidays or cold snaps.
According to the U.S. Department of Energy, water heating accounts for about 20% of a home’s total energy use, meaning even small efficiency gains can have a noticeable impact on household budgets.
The Importance of Flushing Your Water Heater
Over time, sediment from Tacoma’s water supply builds up inside your water heater tank. This layer of mineral deposits acts like insulation around the heating element, forcing your system to work harder.
Problems Caused by Sediment Buildup:
- Longer heating times and higher energy bills
- Reduced tank capacity (less hot water available)
- Loud popping or rumbling noises from inside the tank
- Increased risk of leaks and premature failure
Experts recommend flushing your water heater at least once a year. For families in Tacoma with harder water or heavy hot water use, flushing may be needed even more frequently. If you’ve noticed unusual noises or inconsistent water temperature, it’s a clear sign that sediment may be the culprit.

Signs Your Water Heater Needs Repair
Sometimes a flush isn’t enough. Here are the most common warning signs Tacoma homeowners should look out for:
- Leaks around the unit’s base – Even small drips can lead to significant water damage.
- Rusty or discolored water – Indicates corrosion inside the tank or failing pipes.
- Inconsistent hot water – Temperature swings signal a failing heating element or thermostat.
- Unusual noises – Persistent banging or popping usually means severe sediment buildup.
- Old age – Traditional tank water heaters last 8–12 years on average; tankless units can last longer with care.
If your system is nearing the end of its life or repairs are becoming frequent, replacement may be the smarter investment.
Tank vs. Tankless Water Heaters: Maintenance Differences
Tacoma homeowners often ask about the differences between traditional tank systems and modern tankless water heaters. Both require regular care, but the maintenance looks a little different:
- Tank Water Heaters
- Annual flushing to remove sediment
- Anode rod inspections to prevent rust
- Temperature and pressure relief valve testing
- Tankless Water Heaters
- Annual descaling to remove mineral buildup from heating coils
- Air filter cleaning for consistent performance
- Professional inspection of venting and gas lines
Both types benefit from professional servicing, but tankless systems, in particular, require careful descaling because mineral buildup can quickly reduce efficiency.
If you’re unsure which system you have or how often it should be serviced, contact Bob Larson Plumbing for expert advice.
The Advantage of Professional Water Heater Service
While DIY tutorials exist, water heater maintenance involves gas lines, electrical connections, and safety mechanisms best handled by licensed plumbers. Professional servicing offers:
- Thorough inspections – Identifying issues most homeowners wouldn’t catch.
- Safer repairs – Proper handling of gas, electricity, and pressure systems.
- Warranty protection – Many manufacturers require proof of professional service.
- Long-term savings – Preventing major breakdowns and maximizing efficiency.

How often should I flush my water heater in Tacoma?
Water heater flushing removes sediment that collects inside the tank. This buildup can cause inefficiency, noisy operation, and early failure if left unchecked.
- Standard recommendation: Once every 12 months for most Tacoma households.
- Hard water areas: If your home has harder water, you may need to flush every 6 months.
- Heavy usage: Large families or homes with frequent laundry and dishwashing benefit from more frequent maintenance.
Regular flushing improves energy efficiency and extends your heater’s lifespan.
What are the signs my water heater needs repair?
Leaks, discolored water, strange noises, or fluctuating temperatures are key warning signs. If your unit is over 10 years old, replacement may be a better option.
Do tankless water heaters need maintenance?
Yes—tankless water heaters are efficient but not maintenance-free. They need yearly servicing to prevent scale buildup and keep components working properly.
- Annual descaling – Mineral deposits from Tacoma’s water supply can coat the heating coils.
- Filter cleaning – Tankless units have air and water filters that need attention.
- Venting inspection – Gas-powered models require checks for safe exhaust and proper combustion.
Neglecting these steps can lead to reduced efficiency, longer heating times, or even early replacement.
Why is fall the best time for water heater maintenance in Tacoma?
Fall is the transition season between lighter summer usage and heavy winter demand. Servicing your unit in September offers several advantages:
- Prevents winter emergencies – Catch problems before the cold weather increases system strain.
- Boosts efficiency during peak use – You’ll notice lower utility bills when demand is high.
- Convenience – Service schedules are often more flexible in the fall before the winter rush.
By addressing maintenance now, you avoid the stress of mid-winter breakdowns when hot water is most essential.
Can I perform water heater service myself?
Basic tasks like draining a few gallons of water from the tank are possible for DIYers, but complete flushing, electrical work, and gas line inspections are best handled by professionals for safety reasons.
