[chbot] [OT] plumbing parts for a Gemini Shower

[Andy Gardner]

I didn't say to replace your existing valve.

You install this EXTRA one somewhere in the house where you can get to it easily in a flooding emergency.

Once installed, you'll be able to shut your water off completely for the other repair.
