Title: Too Restrictive to allow air volume needed.
Review: Plug has a tiny hole that is too restrictive to allow enough air volume through to do an adequate job. Hole may be small to attempt "reduce" pressure but that is not a satisfactory way to reduce pressure anyway. Need to reduce pressure on compressor regulator to avoid blowing out lines in RV Make you own adapter using a piece of garden hose, and the appropriate adapters to do a satisfactory job of removing all water from you RV lines for winter storage.
