Why 90% Of New Plumbing Is GARBAGE - The Builder Grade Lie

House Verdict. I am Gus Harlan. Thirty-five years a home inspector, ten thousand houses, and I am done being polite about what is in them. In new construction, especially houses built after 2005, the plumbing is often chosen to pass inspection, not to last. This "builder-grade" approach uses the cheapest parts available, leading to costly failures years down the line. I'll show you why these systems fail, what specific parts are truly garbage (it's rarely the PEX pipe itself), and the six affordable upgrades that can prevent a flooded dining room and save you from a major insurance claim. Learn what to look for and how to protect your home from the hidden costs of cheap plumbing. New video every day. This video is a dramatized story inspired by real places and the kinds of decisions that mountains demand. Names, dialogue, and details have been imagined for storytelling — it's a portrait of how a situation like this could unfold, not a documentary account.
