Recently installed a water softener, outside of house in it's own housing, and in the process I tapped off the supply line from the street to run the outside faucets with PVC. Have 1 outside faucet on the other side of the house which I need to run a line to. In order to do so I need to run a line up the outside of the wall of the house and then make an elbow into the attic where I'll tie into it with pex and run to the other side of the house. When I run it up the wall I could use either PVC or galvanized. Galvanized is good for the strength and PVC for easability. We are talking about a 9 foot section of the wall which is brick that it'll be secured to that I have to go up. I'll have to drill through the brick and feed the pipe through it. Location isn't an area disturbed by anything so it'll be almost never be touched. House is on slab and we rarely freeze and even when it does it always gets above freezing during the day so freezing isn't a concern. Still, I am planning on insulating. Am wondering what others thoughts are on which to use?

I live in Yucaipa, Ca and I am remodeling my small masterbath. I will be replacing the electrical wiring. It is 40 yrs old. I want to tap into my original hot and cold copper water pipes in my garage with Pex and run it all new to my Bathroom. And install a curbless shower (Kerdi) pan. Which would require a 1" deep cutout in the slab. I feel I am more than capable to do a good job and plan to meet code either way. What would be required of me if I apply for a permit to do this? I also plan to remodel the other bathroom and the living room at a later date. How could this effect the other jobs later? skeeter
