Scott laid the pex tubing and finished the French drain.
The pex tubing is the red and blue irrigation tubing that runs through the PVC pipe. It can be seen at the back of the photo. The pex will run into the crawl space beneath the house and connect to the plumbing. In turn, it will supply hot and cold water to the “water”element” shower. The French drain will disperse the water from the shower. The French drain is wrapped in weed barrier and 1500 pounds of gravel were used below and to cover the French drain (which has been completely covered by gravel). One bag and wheel barrowful at a time. Scott has muscles!
