The leak has been found!
The title of this post is probably too exciting. However, I'm thankful that we were able to easily find the leak in our "baptistry." (Thank you for your prayers.) Lord willing, when the patch kit arrives it will take care of our problem. I'm still very thankful that it did not hinder the great day God gave us yesterday. It works so very well to baptize at our home. Our church really enjoyed some good fellowship time yesterday.
By the way, the leak was found a bit more quickly because I told my younger boys, "The one who finds it gets a pound." It took about 3 seconds to find it. (I did give the other boys who did not find it a consolation prize.)
