What happens here
After plumbing demolition, address any damaged subfloor. Use a circular saw to precisely cut out the damaged sections of the subfloor. Once removed, install new pieces of plywood or OSB subfloor to patch the gaps, securing them with nails using a nail gun. With the subfloor repaired, install new PEX water lines (red for hot, blue for cold) and a new PVC drain pipe, connecting them to the main plumbing system. The PEX lines offer flexibility and ease of installation, while PVC is standard for drain lines.
Goal: Repair subfloor and install new water and drain lines.
