People often take hot water for granted. They don’t realize how precious it is until they no longer have access to it. When they turn the hot water faucet on, they expect it to flow out so they can wash clothes, dishes, or take a shower.

Fortunately, water heaters rarely fail without warning. Homeowners should be aware of the signs of a malfunctioning water heater so they can take action before it stops working completely. What are the signs of a failing water heater?

Inconsistent Water Temperature

Many people first discover their water heater isn’t working properly mid-shower. The hot water suddenly turns cold, or the temperature seems to fluctuate. Others find that the water temperature isn’t as hot as it used to be. Regardless of what a person notices during their shower, any inconsistency in water temperature should be investigated, as it is a sign that a problem exists within the unit.

People shouldn’t panic and automatically assume they need a new water heater. Hopefully, the problem is nothing more than a defective thermostat that must be replaced. However, faulty heating elements lead to inconsistent water temperatures, and other issues may also be present. Tankless water heaters often struggle to maintain a consistent water temperature when the pressure-balance valve fails or the pipes cannot handle the household demand.

The best way to determine the source of the problem is to have the unit inspected by a licensed local Arlington plumber. The plumber examines the unit to uncover the issue before making recommendations on repair or replacement. Homeowners should consider the cost of the repair versus the cost of purchasing a new unit when determining which option to select. When making this decision, homeowners should consider the long-term savings associated with upgrading to an energy-efficient model.

Unusual Noises

Water heaters typically operate in the background. Household occupants become accustomed to the noises the water heater makes and never think twice about them. When the unit begins making new noises, they become concerned.

There is reason to worry when a water heater begins making popping, banging, or rumbling noises. These noises typically suggest that sediment has accumulated on the bottom of the tank. If the sediment isn’t removed, the unit will overheat, leading to earlier failure of the device. The noise comes from the water trying to make its way through the sediment layer.

A failing heating element often makes noises. Mineral deposit buildup within the tank can lead to unusual sounds as it clogs the system. Poor water flow or changes in water pressure may also cause unusual sounds to emanate from the water heater and plumbing systems. Loose valves and connections can also result in strange noises coming from the unit.

Contact a licensed professional for a comprehensive water heater inspection. The plumber determines whether servicing the unit will resolve the issue or if a new water heater is needed. They provide the homeowner with options to fix the problem being experienced.

Rusty Water

Water coming from the faucets in the home should be clear and free from impurities. If it comes out murky or rusty, the water heater needs attention. Yellow, discolored, or rusty water indicates that the anode rod in the unit is failing. This rod protects the tank’s interior from corrosion. Once the rod fails, the tank is at high risk of rusting.

Rusty water won’t harm a person’s health, so it might be tempting to ignore this symptom. However, the rusty water can discolor appliances and damage their internal components. Furthermore, rusty water doesn’t taste good. Replacing the anode rods and flushing the unit might be enough to correct the problem.

Call a professional plumber to determine the source of the rusty or discolored water. They examine the unit to identify and resolve the problem. It might be as simple as replacing the anode rod, or the homeowner might discover they need a new unit. Prompt action may help preserve the water heater and save the homeowner money.

Puddles Around the Unit

Any water on or around the water heater exterior must be addressed immediately to prevent damage to the home. If the unit leaks, invest in a replacement. The units are airtight, so the leak indicates that the tank’s structural integrity has been compromised. Water escaping from the unit can cause significant damage to the home in a short time.

Homeowners should inspect their water heaters and accompanying valves monthly for leaks. Look for water dripping from the tank or pooling under the device. Puddles around the unit are concerning, as are pipes that drip water. When any water is present, turn the unit off and contact a plumber for a professional inspection.

The plumber may find that the valves are not fully closed or that one or more connections are loose. Tightening or replacing these components may resolve the problem. However, if water is coming from the tank, a replacement is required. The tank is cracked or damaged and cannot be repaired. Internal corrosion has damaged the unit.

Water Heater Age

Homeowners should consider replacing their water heater before it fails. Most standard tank units have a lifespan of eight to 12 years. Tankless models last approximately 15 to 20 years. A homeowner may closely monitor the water heater for issues or be proactive and have it replaced before problems occur, thereby reducing the risk of significant water damage to the home.

Older tanks are prone to sediment buildup. This sediment may solidify at the bottom of the unit, leading to several issues. The water heater’s efficiency decreases, and the unit will eventually fail. Properly maintaining the unit can extend its lifespan, but water heaters, unfortunately, don’t last forever.

Homeowners often can’t remember when they replaced their units, and some people buy a home with a water heater already in place. Each unit comes with a label that discloses the manufacturing date. If the label is missing or that information isn’t present, visit the manufacturer’s website and enter the unit serial number to learn the date of manufacture.

The water heater style also plays a role in its lifespan. Gas tank water heaters typically last between eight and 12 years, although some units may need to be replaced after just six years. Electric water heaters last longer. A replacement usually isn’t required for ten to 15 years. These models store water in steel tanks, which corrode over time. This corrosion leads to a weakening of the exterior and water leaks.

Tankless models last longer than tank versions. A homeowner might find their tankless model lasts 20 years or more. Choose a model with a steel heat exchanger rather than a copper exchanger, as steel lasts significantly longer.

These models lack storage tanks that are susceptible to rust and corrosion. Furthermore, they experience less wear because they aren’t storing water. They heat water on demand.

Additional Signs of a Failing Water Heater

Homeowners should not assume their water heater remains in good working order if they don’t see any of the signs outlined above. Low water pressure from a hot water faucet, even when the cold water faucet works properly, is a cause for concern. Sediment buildup in the water heater tank causes this problem, which must be addressed quickly before the unit suffers a complete failure.

Limited hot water is frustrating, especially when someone is showering and must rush to get clean before the water runs cold. Sediment at the bottom of the tank reduces the amount of hot water available for household usage. The sediment must be removed to prevent clogged or corroded valves and the need for a new unit.

High energy bills and the need for frequent repairs are two additional signs a water heater is failing. Hot water coming from the faucets in the home should not have an unpleasant odor. This odor indicates that bacteria are growing in the tank. The water must be drained and treated to remove the bacteria, making the household water supply safe to use again.

DIY or Professional Repairs?

Homeowners may consider saving a few dollars by repairing or installing a water heater without professional help. Doing so may be a mistake. Working on a gas water heater can be hazardous, as these units carry the risk of fire, gas leak, or explosion. Electrical models can shock the person working on the unit, and both types may allow scalding water or steam to escape. The person working on the unit might suffer severe burns and injuries when this water is released.

Manufacturers often require homeowners to work with a professional for water heater maintenance and repairs. DIY repairs might lead to the manufacturer voiding the warranty. The homeowner saves money by leaving these tasks to licensed pros.

Licensed professionals quickly diagnose the problem, saving the homeowner time and money. They do the work correctly, which reduces the risk of more severe damage and costly future repairs. Furthermore, they have the training, tools, and experience to ensure the work is done in the shortest time so hot water is restored to the home.

Professional plumbers comply with local building codes and manufacturer guidelines when repairing and installing water heaters. They ensure all connections are safe to reduce the risk of accidents, and most plumbers guarantee their work, giving homeowners peace of mind.

Homeowners remain responsible for their water heaters, even when professionals handle many of the repair and maintenance tasks. Regular inspections catch problems early, allowing a plumber to be called for repairs or the installation of a new unit. Between professional inspections, homeowners may flush the tank to remove sediment, adjust the thermostat to the desired temperature, and monitor the anode rod to prevent rust. Maintaining the unit and working with a professional for repairs and installation will reduce the risk of problems and extend the unit’s lifespan.
