Sediment buildup is one of the most common causes of reduced water heater efficiency.
How often should I use the drain valve?
Most tanks benefit from an annual flush; hard‑water areas may need more frequent flushing.
Why is my drain valve leaking?
The valve may be worn or have sediment stuck in it. Replacement is often the best fix.
Can I replace a drain valve myself?
