What is the proper spacing for installing 1/2" PEX tubing under 3/4-inch oak floors for radiant heat? I am putting the PEX piping into U-shaped aluminum, mounted on 3/4-inch plywood strips over a plywood sub-floor. Thank you in advance.
How can I install in-floor heat with PEX piping on an existing cement slab on grade?
I want to run a new water line to a bathroom(recently added on to our home's main floor) and the existing plumbing is copper piping. Can I use plastic piping for the new water line, or does it have to remain copper all the way to the fixture?
