Aside from a cold surprise from hot water taps, there are many signs you need water heater replacement. Some are more subtle than others. Recognizing when the appliance may be at the end of its life can save on emergency repair costs. Instead, you can replace a water heater and invest in a high-efficiency or tankless model. The following signs indicate it’s probably time for a new system:
Your Water Heater Has Reached Its Expected Lifespan
Water heaters typically have a 10- to 15-year life expectancy. A tank-type model may last as little as eight years while a tankless water heater can last up to 20 years. Signs your water heater is working less effectively may appear once it’s about a decade old. That doesn’t mean the unit doesn’t have some life left to it.
However, you should check its age. The date or encoded serial number should be on top, or the outer casing. Entering the serial number on the manufacturer’s website reveals when the unit was built. If it’s over a decade old, consider replacing a hot water heater.
There’s Less Hot Water
Running out of hot water more quickly is a sign your water heater is past its prime. Showers turning cold can be due to sediment buildup, which can be flushed. If a heating element is failing, a technician may be able to replace it and preserve your water heater. Sometimes, a malfunctioning thermostat is the culprit. Replace your aging water heater if these issues occur all at once or more frequently.
Your Water Heater Is Noisy
Banging, rumbling, knocking, gurgling, or popping noises can mean sediment is building up in the tank. Over time, sediment can damage the heating element. Any unusual sounds require calling a professional to assess the problem. They can also mean your water heater is reaching the end of its life, especially if mineral buildup has caused metal parts to deteriorate or major components to break down.
The System Produces Rusty Water
Water should always emerge from faucets clear. If it’s rusty, cloudy, or otherwise discolored, this is a sign parts inside your water heater are degrading. Corrosion of the inner tank is one possible cause. Or, sediment is mixing with the water being supplied to fixtures.
If it’s producing rusty water, your water heater may soon develop a leak. It’s not only unpleasant to look at. Water that looks rusty can be a health hazard. Call a professional before it causes harm or a leak leads to water damage. A likely scenario is the sacrificial anode rod has failed and your water heater is rusting on the inside. Therefore, it must be replaced.
Hot Water Doesn’t Smell Right
As a water heater breaks down, metal flakes and particles from the inner tank can mix with hot water. They can give your hot water a metallic smell and taste. This isn’t something to ignore. It’s a sure sign of a problem, so consult with a plumber to determine if it’s time to consider water heater replacement.
Moisture or a Leak Forms Around the Water Heater
Water heaters are built with impermeable materials. Therefore, water should always be contained inside. If there’s any amount of water outside the tank, it’s a sign the unit is failing. A leak can also lead to an explosion, especially if it’s coming from the pressure relief valve.
Leaks related to corrosion often start subtly. The outside of the tank may seem slightly moist or have small drips of water. A puddle under your water heater is a sure sign it has failed. Without replacing the appliance, serious water damage to your home can occur.
Visible Damage
If the tank, pipes, connections, and other components look rusted or corroded, other parts of your water heater may also be deteriorating. Corrosion weakens the unit’s structural integrity. The water heater should be replaced. The same is true if you see cracks in the tank or other types of physical damage.
The Pilot Light Keeps Going Out
If you have a gas rather than an electric water heater, hot water issues may not be the only sign of trouble. A pilot light allows the unit to produce heat that increases the water temperature. It can usually be relit if it goes out. However, if the pilot light doesn’t come on, it is difficult to relight, or it goes out repeatedly, the thermocouple or other components may be faulty. If the issue persists, consider replacing the system.
Higher Energy Bills
A water heater’s efficiency decreases with age. If you’ve been using about the same amount of hot water and your energy bills spike, it may be time to replace your older water heater. Consider buying a new one if the unit also struggles to maintain a comfortable water temperature. Purchasing an energy-efficient model will cost you upfront, but over time you can save money with water heater replacement.
Major Repairs Are Needed
Needing frequent repairs is a sign your water heater is close to the end. You must pay for parts and labor each time the unit is fixed. While the occasional heating element, valve, thermocouple, igniter, or thermostat repair might make sense, expensive repairs aren’t worth it if your water heater is over 10 years old. There’s also no sense in fixing one with a cracked tank, leak, or extensive corrosion.
Should I Replace My Water Heater Before It Fails?
A preemptive replacement can avoid a catastrophic failure that results in a flood. It can also prevent a breakdown, so you won’t need an emergency water heater repair professional, which can be expensive. Investing in water heater replacement before the unit fails can save you stress, time, and money.
Should I Replace a Water Heater If I Plan to Move?
Water heater replacement is a long-term investment. Repairing the unit, if possible, makes more sense if you don’t plan to stay in your current home for long.
