I used ADB for years, but I recently started using two Android apps, Canta and Shizuku. With these two apps you can uninstall any app (even the hidden ones) directly from your phone without connecting to a computer. I can be a little tricky to set up, but it’s by far the best and clearest method for uninstalling bloat and spyware from your phone. Even better than Universal Android Debloater (which is still a great option).
Fwiw
The expansion tank isn’t just for the water heater. That increased pressure puts undue strain on the entire plumbing system in your home. It will cause toilet fill valves to fail, supply lines to rupture, and possibly even pinhole leaks. A lot of plumbing issues are solved by installing an expansion tank.
