Good video Ray, those check valves always go bad at the wrong time. I have a inline ball valve just inside that we shut off when we are not using the city water inlet.Just in case the city water inlet wants to leak.
Happy Trails...Pal!!!

Good work and job well done. What your temp Ray its chilli here in Colorado.

Good idea!

Currently around 49F looking for a high of 65F and sunny. :) We've had a pretty good stretch of weather the last week or so about 10 degrees above average and less cloud and rain than normal.
Here is my weather station data. It uploads to the web. :) - https://ambientweather.net/dashboard/597ca285e8b933fa92574cc4e7427721

Thanks that's a nice station. like the solar radiation reading.

I had this same problem years ago. At the time, the thing that bothered me was that all of the replacement water fill parts had different mounting screw patterns and dimensions. I wasn't happy about having to drill new holes on my water bay. Finally, I just did it anyway. But, prior to replacing this fitting I bought a plastic ball valve and connected it to the original (leaking) city water fitting. I could then turn the valve off and stop any leak out of the fitting. When I connected the hose from the water spigot I just turned the ball valve back on again. I guess I could have just used a plastic threaded plug instead but I liked the valve better. As Ray and others have pointed out- there's a lot of ways to deal with this. Fortunately, this is one of those really easy-to-do fixes. Also, I like that Rescue Tape too...I have it in many colors as well. Last year we developed a leak in our house under a bathroom vanity sink. A p-trap that was bonded to the drain fixture had cracked and water was all over the bottom of the vanity. The drain pipe was part of a Grohe (expensive German piece) that was part of the sink fixture package. This wasn't going to be easy to find as a replacement. I decided to just wrap the connection with a few turns of Rescue Tape. -It's still holding.
