In order for the plumbing portion of a 4-point inspection to be deemed favorable, the water heater must be in adequate condition and should have sufficient useful life remaining. The typical useful life of a water heater is 12-15 years; however, if properly maintained they can last longer. Water heaters 20 years old or older are typically required to be replaced.
The following are plumbing materials acceptable for a 4-point inspection:
· PVC
· CPVC (Chlorinated PVC)
· Copper
· Cast iron
· Galvanized piping
Although there are a few exceptions, generally speaking, PEX (polybutylene or polyethylene) piping in any portion of a plumbing system will likely result in an unfavorable 4-point inspection and replacement of the ineligible pipes would be required prior to binding your homeowners insurance policy. PEX plumbing is ineligible due to the fact that the material is often installed incorrectly or fails to work properly due to design/manufacturing defects and increases the likelihood of there being an insurance claim in the future.
Some common plumbing problems that may need to be addressed following your 4-point inspection include: Rusted or corroded pipes, leaking pipes, unvented TPR valve and existing water damage
