Sounds like a GOOD plan Bro!!!
No I work for a local Independant company... we don't do much plumbing (thank goodness) but I still don't like to give out the Big Boxname just the same. I work for Haywood Builders Supply.
www.haywoodbuilders.com but we are right in the middle of a total SITE re-vamp so don't judge me on the site.. not just yet!! LOL!!
Call if you need any help bro!! When you go, get the parts to where you can simply unscrew and remove the valve and put everything like new when it's time to move.
