My home is currently in the framing stage and about a couple of weeks from the rough plumbing. I have a large shower in master which will have the plumbing valves/etc on the ICF wall. I am concerned about how these will be attached. Could someone plese ease my mind! I would like to know more than my plumbers. I know they have never plumbed an ICF home. Moving the valves to a conventional wall is not an option. If I could do that I would not be so worried. Thanks, Mike McClane Tomball TX

Simple, just remove the foam (no more than necessary) to acommodate all necessary pipes, and lines. At points of attachment remove the foam all the way to the concrete and attach direct to concrete with standard pipe hangers spaced to your local code. After inspection fill all necessary gaps with spray foam.

Moving the valves to a conventional wall is not an option.????

The only time this happens is when the shower door is swung the wrong way and already purchased!

Although not evil, placing the water lines on exterior walls is not wise...however, I see you are in Texas, so no freezing, right, so go for it.

You may review placing blocking in the wall to attach the lines to, or you could build a padded out wall using 1 x stock so you have some room to play.

Thanks guys. I figured it would not be a problem. The home is located just outside Houston TX so freezing is not a problem. We might have two or three days in the winter in which the temps drop below freezing but even that is unusual. There are no shower doors on this shower because it is so large. The only standard wall avaliable would be at the entrance so my beautiful wife already said no to that. So, I assume you attach things to the concrete using tapcon fasteners correct? Thanks for the help. I have researched many things on this forum and have always found the answers. I am doing my part to educate my friends about building the "right way" with concrete!
