## NHTSA's summary

It has been determined that units in this campaign were built without the galley grey tank vent pipe being routed to the exterior of the unit. The following procedure describes how to finish the venting of the pipe, located under the kitchen countertop, to the outside of the unit. The remedy is to locate the vent pipe in the cabinet under the kitchen sink and finish installing it through the sidewall.
