Causes of Water Heater Leaking From Side

Understanding the causes of water heater leaks from the side helps address the issue quickly and effectively. Here are the common culprits:

Corroded Tanks

Corrosion occurs over time, particularly in older water heaters. When rust develops on the tank, it can create holes, leading to leaks. Regularly check for signs of corrosion, such as discoloration or rust spots. If you notice significant corrosion, consider replacing the unit.

Loose Connections

Loose connections can create gaps where water escapes. Inspect all connections within the plumbing system, including inlet and outlet pipes. Tightening these connections may resolve the leak. Use plumbing tape if necessary to ensure a secure seal.

High Pressure

High water pressure can trigger leaks. Residential water pressure should ideally stay between 40 to 60 PSI. If pressure exceeds this range, it might activate the pressure relief valve, causing leaks. Consider installing a pressure-reducing valve to maintain appropriate levels, and regularly test the pressure with a gauge.

Identifying the Symptoms

Recognizing the symptoms of a leaking water heater is crucial for preventing further damage. Look for the following signs that may indicate a leak.

Warning Signs of a Leak

Puddles on the Floor: Water pooling around your water heater is a clear sign of leakage. Even small puddles can indicate a problem that needs immediate attention.
Increased Water Bills: A sudden spike in your water bill without changes in usage often points to hidden leaks. Monitoring your bills can help you catch leaks early.
Visible Rust or Moisture: Rust forming on the water heater or surrounding areas shows prolonged exposure to moisture. Check the exterior of the unit and the connections for signs of rust.
Water Stains on the Wall: Stains or discoloration on walls near the heater may indicate leaking water running down the surface. Assess any affected areas closely.
Unusual Noises: Sounds, such as hissing or banging, could suggest water escaping or pressure changes within the tank. Pay attention to these noises during heater operation.

Inspect Surrounding Areas: Look for water damage in nearby walls or flooring. Use a moisture meter if available to assess the extent of the issue.
Check Insulation: Inspect the insulation around the pipes and tank. Wet insulation can lead to mold growth, so address any moisture quickly.
Examine Appliances: Assess any appliances downstream from the heater for water damage. This includes checking cabinets and under sinks connected to your water system.
Evaluate the Foundation: If your water heater is in the basement, check the foundation for any signs of moisture intrusion or mold. This can signal a more significant leak issue.
Document Everything: Take photos of any damage for insurance purposes. This documentation helps when discussing repairs with professionals.

By proactively identifying and assessing these symptoms, you can address water heater leaks effectively, preventing more severe problems down the line.
