· Possible Major Concern: This home has polybutylene (PB) water piping installed. This pipe has a history of failure at the connections, especially in homes with higher water pressures, and there have been class action lawsuits over this type of piping. I recommend that a licensed plumber evaluate the entire plumbing system for piping integrity.
Also, if you are not in the habit of checking water pressure, I recommend that you start. Last house I inspected had a water pressure of 102 psi. You'll notice that the max pressure rating on PB is 100 psi. Realtor tried to argue that since it hasn't failed yet that it wasn't an issue and that the higher pressure was good for water flow.
