Just replaced my 23 year old gas water heater and now I have a water drip at the connection of where my flue meets my chimney. This replacement was pretty straight forward and was very easy as everything lined up perfect with old plumbing and exhaust flue. I noticed the day I replaced the water heater that I had some water on my work bench and the concrete wall had a water stain on it. I didn't think any thing of it and thought maybe I got water over their when I was hooking up new heater or from the old water heater when it blew. Any ways I went down stairs to check on water heater today and saw that my work bench had a puddle of water and I saw a drip in progress at the flue. I just did the replacement on Tuesday. Any thoughts would be appreciated. Thanks in advance.
