One of many things a homeowner does not want to deal with is a water leak. We discovered a puddle by the water heater, a bad sign. The water heater tank drain valve failed and was leaking, not the tank itself. In the photo there’s a short copper pipe screwed in where the valve was, a placeholder while the plumber went to get a replacement valve.
This was a much less expensive fix than replacing the entire water heater. My budget is very thankful!
