The adopted plumbing code and a manufacturer's installation instructions differ on the maximum length of a listed flexible water connector. Which controls, and what is the guiding principle?
a.The code always wins even for listed products
b.Ignore both and use judgment
c.The more restrictive requirement governs; listed products must be installed per their listing where the code defers to it
d.The instructions always win over any code
Explicación
When a listed product's instructions and the code both apply, the more restrictive requirement governs, and the code generally requires listed products to be installed in accordance with their listing where it defers to the manufacturer. This protects the listing's validity while still meeting minimum code. The plumber documents which requirement was applied.
