Not a great picture, but an unscheduled DIY - and took the picture as a shopping reference. Discovered slight stream of water on garage and identified source was cold water intake of hot water heater with sticker showing install date of 7/2004. Still works, so definitely got my money worth out of it, and even if replaced would still have the current problem to resolve. The problem is that the connectors, one of which split causing the leak, are no longer made, so have to "modernize" the connection. Thought I had it with two 3/4" female threaded to PEX connector, one of which fit fine at the hot water heater, but the pipe elbow connection needs a 1" to 3/4" reducer. They do make it, but note stocked by anyone, including local dedicated plumbing supply warehouse and Amazon overnight, with order delivery next week for each source. Too long to wait, so back to the drawing board today.
On a side note, I have no idea why they design, even today, the electrical connection without waterproof sealing since top leaks are not that uncommon. It was filled with water that I sucked out with a shop-vac and cleaned the connections.
