  • Pipe weapons are 20%/40%/60% cheaper to repair.
  • Prior to patch, the condition loss bonuses provided by each rank of the Licensed Plumber perk were 30%/60%/90%. Afterwards, they were reduced to 20%/40%/60% and the repair bonuses have also been reduced, to match the Power Patcher perk.
  • This perk does not affect the lead pipe despite having "pipe" in its name.
  • The analogous perk for armor is White Knight and Power Patcher for power armor. The closest analogous perk for non-pipe weapons is Gunsmith, though the perk has a maximum effect of 50% over five ranks rather than 60% over three ranks, as well as including access to higher-tier gun crafting recipes.

Behind the scenes

The Vault Boy is based off the Fallout: New Vegas perk Jury Rigging. The Fallout: The Roleplaying Game version of Jury Rigging also uses the Licensed Plumber version of the Vault Boy.
