The water valve is not a safety device. It is simply placed where it is as a matter of convenience. If you didn't have such a valve and you needed to replace a sink (or toilet) you would have to turn the water off to the entire house.
My villa does not even have an expansion tank. So clearly some of my valves may be getting a little weaker with age and occasionally pop off. Sure, I could replace them, or perhaps unstall an expansion tank which is not required, but why bother spending the money? My solution has worked flawlessly for years AND I haven't even had to use any of the valves in question! So, I haven't had to cut and replace any cable ties!!

Ok makes sense except……
It is Florida code since 2000 I believe that it is mandatory here to have an expansion tank unless you have a tankless water heater..
Basically most homes built south of 466 and north of 44 have expansion tanks. And a few neighborhoods south of 44.
If you do not have an expansion tank on top of your hot water tank then you have a thermal expansion valve and they can also fail in fact most homes over 10 years those thermal expansion valves are leaking and most plumbers will come in and replace them with an expansion tank because it’s Florida code now.
I don’t like the expansion tanks because they fail constantly between three and five years. But you can’t fight Florida code. I personally think it’s an extremely poor design and every single home we do service on with we check the expansion tank and approximately 70% we find bad that are more than 3 to 5 years old. I believe they were improperly installed from day one because they never pressurize those tanks correctly therefore failing prematurely.
Step 1. Pressurize the tank before installation to the house pressure.
I have seen several plumbers in fact some of the main plumbers in the villages that do not do this? They take it off the shelf at 25 psi slap it on and they fail in three years? Now your expansion tank Brand New and is 50 psi below the operating pressure so of course it will fail prematurely.
