Looks good, Dennis. We also put a valve at the tank, for easier swap. By orienting the tank with potable connection on top you eliminate air in the tank, also if bladder fails you have less water spillage when replacing. Your right about tight, too. It’s easy to damage brass threads especially when using Teflon tape and dope, but it’s a great joint when done right.

I have a large expansion tank (25 gal with a solenoid attached). How does this work? It is located on the incoming cold waterline. I power flushed (well pressure) the hot water tank today until it ran clean, but suspect the expansion tank also needs flushing. The expansion tank has a rusty pipe plug (for drainage?) but I am cautious without understanding how it works (why the solenoid?).

thanks for the video, I was looking into installing an expansion tank mostly because when I close a faucet I hear the pipis banging. Sadly my water heater is installed directly soldered to copper pipes, no flexible. I will need to hire a plumber to put a T in there, or may be I can install it somewhere else.
