The answer to 'my water heater installation is leaking' is that there are several common causes for a leaking water heater installation, including improper installation, faulty components, or normal wear and tear. Symptoms may include water pooling around the base of the heater, rust or corrosion, or reduced water pressure. Solutions can range from tightening connections, replacing washers or gaskets, to fully replacing the water heater if the leak is severe.
In many cases, a minor leak may be fixable with some basic DIY troubleshooting and repairs. However, if the leak is significant or the cause is unclear, it's best to call in a professional plumber to properly diagnose and resolve the issue. Attempting complex repairs without the right skills and equipment can lead to further damage or safety hazards.
