Knoxville Hot Water Heater Maintenance

Comprehensive Routine Water Heater Maintenance Services

Regular maintenance for your water heater and plumbing system isn’t just recommended, it’s essential. Just like changing the oil in your car, preventative maintenance can help extend the life of your water heater, improve energy efficiency, and reduce the risk of unexpected, costly repairs or replacements. Plumbing industry experts recommend scheduling routine water heater maintenance including water heater flushes at least once a year, so if you can’t remember the last time your water heater was serviced, be sure to contact Pipe Wrench today!

At Pipe Wrench Plumbing, Heating and Cooling we provide maintenance services for all water heater makes and models including conventional “tank style”, tankless, gas or electric. Our certified and experienced plumbing technicians will perform the preventative maintenance tasks required to keep your water heater working at peak performance while ensuring your home and family have hot water needed for everyday tasks. During our maintenance inspection, we also will identify any possible issues with your water heater and provide the best long-term solution before major problems occur.

Regular water heater system checks and flushes are important for every home, but they’re especially crucial in areas with hard water, like Knoxville, TN and the surrounding communities. Hard water is rich in minerals such as calcium and magnesium, which can build up over time and form limescale deposits inside your water heater, reducing its efficiency and damaging components. Without routine maintenance, these systems are more vulnerable to corrosion, leaks, and unexpected breakdowns, resulting in expensive repairs or early replacement.

What are the Benefits of Routine Water Heater Maintenance?

Water Heater flushes and system checks are recommended at least once a year by industry experts, and sticking to a routine maintenance schedule comes with several benefits including:

Extended Life Span: Proper maintenance can help extend the life span of your water heater, normally between 8-12 years, helping you to avoid frequent repairs or premature replacement costs.
Improved Energy Efficiency: Routine maintenance improves the efficiency of your water heater meaning it doesn’t have to work as hard to heat your home’s water supply, resulting in reduced energy consumption and lower utility bills.
Enhanced Safety: Regular tank flushes and system checks ensure that safety features such as the pressure relief valves, thermometers and gas controls are functioning properly for increased safety.
Consistent Hot Water Supply: Well-maintained water heaters are less likely to experience breakdowns, leaks or unexpected outages, ensuring a reliable supply of hot water for your home.
Cost Savings: Regular water heater maintenance can save homeowners money on energy bills and costly repairs or replacements by preventing major issues upfront while also helping to improve efficiency.
Warranty compliance: Many water heater manufacturers require regular maintenance as a condition for warranty coverage. Neglecting routine maintenance can void your warranty, leaving you responsible for any repair or replacement costs.
Less Environmental Impact: Increased water heater efficiency means less energy is wasted during water heating, reducing your environmental footprint.

What are Common Water Heater Problems?

There are often warning signs that you need to contact a plumbing professional for water heater maintenance and depending on the severity of the issue, repairs or even replacements may be required. By regularly scheduling routine water heater maintenance and flushes at least once a year, you can help prevent minor issues before they become major and potentially costly problems.

Inconsistent Water Temperature:

Whether it’s a gradual loss of heat or a sudden drop, fluctuating water temperatures are often due to corrosion or sediment buildup around the heating element, a malfunctioning thermostat or other failing components. If your water heater isn’t providing consistent hot water, it’s time to call a professional for routine maintenance or repairs.

Leaking and Pooling Around the Water Heater:

Water heater leaks can be caused by loose waterline connections, a buildup of mineral deposits, or corrosion from hard water. Over time, small holes may form inside or at the base of the water heater, and if left unaddressed they can lead to system failure and costly water damage. Leaks can be difficult to repair and if major corrosion is detected, it may be more cost effective to invest in a new water heater, rather than sinking money into frequent repairs.

Unusual Sounds:

Older water heaters may start making strange noises like banging or knocking coming from the tank or connected pipes. These sounds often indicate a buildup of sediment or minerals inside the tank. If not regularly flushed out, this sediment can damage the heating element or cause corrosion, eventually leading to component damage and leaks. High water pressure can also cause unusual noises and may require the installation of a pressure-reducing valve or an expansion tank.

Water Pressure:

Since your water heater is integrated with your home’s entire plumbing system, any problems with it can impact overall water pressure. Common culprits often include a faulty pressure relief valve, sediment or mineral buildup inside the tank, clogged pipes, corrosion, improperly sized piping, or issues with the expansion tank (if your system has one). A licensed plumbing professional can accurately diagnose the cause and recommend the best solution.

Water Heater Maintenance FAQs

How often does my water heater need to be serviced?

Plumbing industry experts recommend scheduling professional water heater maintenance at least once a year to keep it in top condition. Water heater maintenance helps improve your unit’s energy efficiency and prolongs its lifespan. Maintenance service should always include a water heater flush to clean the tank and remove sediment and mineral buildup. In areas with hard water, like Knoxville and East Tennessee, it may be helpful to schedule maintenance services every 6 months.

What regular maintenance does a water heater need?

All water heaters require routine maintenance to help with performance, energy efficiency, warranty compliance, and to extend the lifetime of the unit. Crucial maintenance tasks include flushing the tank, checking the heating elements, testing the pressure relief valve, inspecting the anode rod, and checking for leaks to name a few.

What happens if you never flush your water heater?

Failing to flush your water heater allows sediment and minerals to collect inside the tank, which can decrease efficiency, reduce your hot water supply, and lead to corrosion. Over time, this not only raises your energy bills but can also cause serious damage such as a ruptured tank and costly water damage.

Can I flush my water heater myself?

Yes, you can usually flush your water heater yourself, but it’s highly recommended to schedule maintenance services including water heater flushes with a certified plumbing professional to protect your water heater and yourself. Many water heater warranties can be voided if you perform maintenance yourself such as water heater flushes, so be sure to contact a professional plumber for maintenance services to ensure your home’s water heater is protected.

How long does it take to flush a water heater?

Flushing a water heater typically takes between 1–2 hours depending on the model and size of the tank. This includes the time needed to drain the tank, flush out sediment, and refill the tank. Tankless water heaters may take less time to flush.

Do tankless water heaters need to be flushed?

Yes, tankless water heaters need to be flushed regularly, even though the process takes less time than with conventional “tank style” water heaters. All water heaters need to be flushed at least once a year, to remove sediment and mineral deposits that can affect performance and efficiency, even though buildup in tankless models is often less than conventional tank style models.

How often should I change the anode rod in my water heater?

The anode rod in a water heater typically needs to be replaced every 3 to 5 years. However, different factors such as water quality (especially hard or acidic water) can shorten the lifespan of an anode rod. It’s often recommended to have your water heater’s anode rod inspected annually as part of routine water heater maintenance. The anode rod is a metal rod inside your water heater tank, usually made of magnesium, that helps protect the tank from corrosion caused by minerals and other elements in your water supply.
