Water heaters make it possible to take a hot shower, wash clothes or wash dishes properly. If your water heater is leaking, it may be a sign of serious damage that needs to be addressed immediately. You should contact a water heater leak repair service company quickly to potentially save your water heater and prevent secondary property damage.
Why Is My Water Heater Leaking?
TL;DR: Your water heater may be leaking because it’s old, the tank is corroded or because of an improperly functioning temperature and pressure (T&P) release valve. The full list of possible issues includes:
- Corrosion and rust
- Loose inlet or outlet connection
- Faulty drain valve
- Broken T&P valve
- Sediment buildup
- High water pressure
- Cracked tank
- Condensation issues
- Old age
9 Common Causes of Water Heater Leaks
1. Corrosion and Rust
Over time, the anode rod won’t be able to attract the minerals that can rust a water heater’s tank. Ultimately, the tank will be vulnerable to tears or other defects that can ruin the unit.
2. Loose Inlet or Outlet Connection
Over time, metal fatigue and thermal expansion can result in loose inlet or outlet connections. This may result in a leak as water won’t be able to go directly into the tank itself.
3. Faulty Drain Valve
Corrosion, cracked fittings or loose connections may be signs of a potential leak. A loose valve can typically be tightened while a corroded or cracked valve will likely need to be replaced.
4. Broken Temperature & Pressure Relief Valve (T&P Valve)
Defective T&P valves will either refuse to open or will remain stuck in the open position, which can make it difficult to properly release heat or pressure from the tank.
5. Sediment Buildup and Overheating
Sediment buildup makes it harder for heat and pressure to flow through the tank, which can lead to inconsistent water temperature and pressure. Flush the unit annually to avoid sediment issues.
6. High Water Pressure
Too much pressure going through the unit can cause stress fractures throughout the tank. Tools are available to help monitor indoor water pressure so that adjustments can be made if necessary.
7. Cracked Tank (Internal Storage Tank Damage)
Water heater tanks are constantly exposed to various water temperatures and pressures. These cycles cause them to expand and contract and can result in cracks ranging from hairline defects to significant fractures that cannot be fixed.
8. Condensation Issues
Condensation may resemble a leak as water may pool on the top or bottom of the water heater. However, condensation can generally be resolved by maintaining proper water temperatures and engaging in other routine maintenance.
9. Age of the Water Heater
A gas tank water heater can last for up to a decade while a tankless electric unit can last for up to 20 years. Common signs that it’s time to replace your unit include inconsistent water pressure or increasing water bills.
Signs Your Water Heater Is Leaking
Common signs of a water heater leak include water pooling on the floor, which is typically red or rust-colored in nature. This is often due to the fact that sediment has built up in the tank.
The sediment then mixes with the water as it leaks through the tank. You may also hear a whistling noise when the unit runs indicating high pressure or other defects that can cause a leak to occur.
What to Do Immediately If You Find a Leak
1. Turn Off Power (Electric or Gas)
Turning off the power to the unit can minimize the risk of an electrical fire or explosion.
2. Shut Off Water Supply
Shutting off the water supply minimizes the amount of water that can cycle through or leak from your water heater.
3. Drain the Tank
Draining the tank makes it easier to locate the cause and source of the leak, and it may prevent further damage that might make repairs impossible.
4. Locate the Source of the Leak
Depending on whether the leak is coming from the top, bottom or a valve can help you determine if your unit is fixable.
Can You Repair a Leaking Water Heater?
It may be possible to replace a valve that is stuck or otherwise not working properly. However, if the water heater is leaking from the bottom or top, it may be best to simply replace it.
How to Prevent Water Heater Leaks (Pro Tips)
1. Flush the Tank Yearly
2. Check the Anode Rod Regularly
3. Maintain Safe Water Pressure Per Manufacturer Instructions
4. Install a Leak Detector Alarm
5. Schedule Annual Professional Inspections
Cost of Repairing vs. Replacing a Leaking Water Heater
Water heater replacement costs vary depending on the parts needed and the age of the unit. It can cost as little as $100 or as much as $2,000 or more to repair your existing unit. Meanwhile, a new water heater can cost anywhere from $600 for a basic tank model to $3,500 for a high-end tankless model.
FAQs:
Why is my water heater leaking from the bottom?
A water heater may leak from the bottom because of old age, a faulty T&P valve or other issues such as sediment buildup or corrosion.
Can a leaking water heater be repaired?
Loose fittings or valves may be repaired easily and affordably. However, a full replacement may be best when dealing with a cracked tank or other serious defects.
Is a leaking water heater dangerous?
Leaking water heaters may leave your home vulnerable to water damage, and the leak itself may be a sign of a serious defect that could result in a natural gas leak or an explosion.
How long will a leaking water heater last?
A leaking water heater might last for a few hours to a few days depending on where the leak is located.
Should I turn off my leaking water heater?
Ideally, you’ll turn the power to the water heater off as soon as possible to make it easier to safely work on.
