According to Blake Mowe, Director of Operations at Plumbing Express Atlanta, many savvy home sellers replace polybutylene prior to listing their home.
“Many buyers walk away from a property when they see poly because they don’t want to go through the construction process and don’t know how easy the process can be when you work with us. Most sellers wind up dropping their price to more than it would cost to re-pipe the house, and when they finally find a buyer, they may still want the home re-piped. It’s in the seller’s best interest to replace the pipe upfront and to sell the home with a warranty on the new plumbing.”
You should absolutely replace polybutylene before selling your home
