Boiler Feed Water

(OP)
Assembling Once Through Steam Generator (OTSG). Work is complete & preparing for the final hydro test. In reviewing the hydro test package & P&ID I noticed the Boiler Feed Water main check valve has a 1” bypass installed I am pretty sure this is not to code can anyone confirm if this is allowed.

RE: Boiler Feed Water

Bypass is allowed and it becomes part of the ASME boiler external. It shall be designed per Code.
