Common Causes of Leaks
Understanding the common causes of leaks in your water heater is essential to effectively address the issue. Several factors can contribute to leaks from a small hole on the top of the water heater.
Corrosion
Corrosion occurs when rust builds up inside the tank, often due to age or poor water quality. If you notice a brown or reddish tint to the water or flaking around the top, corrosion may be the culprit. In cases of severe corrosion, replacement of the water heater may be necessary. Regularly inspecting the tank for signs of rust helps in catching this issue early.
Loose Connections
Loose connections can lead to water seeping out at the joints. Check the connections for tightness. Tightening them with a wrench can often resolve the leak. Use thread seal tape on threaded connections to ensure a tight seal. Regular maintenance checks on fittings can prevent leaks from occurring and extend the life of your water heater.
Pressure Issues
High water pressure can stress your water heater, causing leaks. Normal water pressure ranges from 40 to 60 psi. If your pressure gauge reads higher than this, consider installing a pressure reducing valve to maintain appropriate levels. Monitoring water pressure not only prevents leaks but also protects your plumbing system.
