Is it against code to combine a hot and cold supply line into a tee, and then run a single line to a plumbing fixture? I know this is an odd question, but I actually have a need for this.
If this is a code violation, what if I put a check valve in between both the hot and cold supply lines before combining them? Would this be considered within code?
