I just have a generic (non-code) question about running hot/cold supply lines in a ceiling/floor joist cavity. I have always wondered this about other professionals practice regarding the placement of hot/cold supply lines in a ceiling/floor joist cavity. I've never really thought about which line (hot or cold) should be higher when they are both running mostly parallel in the same ceiling/floor joist.
In a new construction situation... Assume that you have your main hot and cold supply lines running mostly parallel in a single ceiling/floor joist. So that you don't cross the hot/cold lines when inevitably some turns need to be made, you would have to run one line (ex: cold) a few inches above the other line (ex: hot) even though these lines are running mostly parallel in the same cavity.
As far as I am aware, there is no code requirement that mandates that one line (ex: cold) has to be placed higher than the other parallel line (ex: hot). So, I was just wondering. Do you guys have a preference which line you like to run higher in a long run within a ceiling/floor joist cavity?
