I recently replumbed a house with PEX. The house was sitting on a crawl space with nothing but gravel for a floor. Simply resting the PEX on the ground didn’t seem like a good idea, but I was a bit mystified as to how to support the flimsy tubing as it ran from the utility room to each fixture. Then it dawned on me. Everywhere there were water supply lines running, there obviously were drain lines as well. Nice, sturdy, well-supported ABS plastic lines. So why not use those to support the PEX? It worked fabulously. I just zip-tied the PEX right to the lines. No muss, no fuss.
