Hey! any plumbers out there because I've just had my plumbing overhauled with copper and the hot and cold water returns were placed in my floor instead of the wall where they were before. Question: Was that necessary given the old galvanized plumbing was coming through the wall before? I asked the plumbing company who did the job and he told me that the reason they moved the lines under thefloor was because the Indiana code is that it should be done that way when the returns are near and outside wall where the cold can freeze and burst the plumbing. Is this true or is this a ploy to keep from putting inside the wall? HELP AS SOON AS POSSIBLE!

Hi housewife:

I built my house including plumbing and electrical and passed inspection. I'm in Canada however and your codes are likely different. However, on my outside walls where water lines occurred I put them inside the house(warm side that is). Regardless of any extra cost this is always the wisest thing to do. Less heartache downstream.

Good luck

I have done plumbing work to my home, recently installing an addition which added a shower stall. All plumbing was added to either interior walls or in the floor (we tore out the ceiling under the bath to have full access to add new drains, new pipes, etc.) I'm in MI and the inspector said this was the way to do it. It prevents problems with freezing, etc.
Good luck
