The answer to 'water heater clogged' is that a clogged water heater is typically caused by sediment buildup from hard water or debris entering the tank. Symptoms include reduced hot water flow, longer heating times, and strange noises coming from the tank. To address a clogged water heater, you can try flushing the tank or using a water heater flush kit, which involves draining the tank and running a cleaning solution through it. However, if the clog is severe or the tank is old, it's best to call a professional plumber to inspect and repair the issue.
Attempting to unclog a water heater yourself can be dangerous if you're not experienced, as it involves working with high-pressure hot water and electrical components. A professional plumber has the right tools and expertise to safely diagnose and fix a clogged water heater, ensuring it's operating properly and efficiently.
