While repairing a burst water pipe in town, Bob turns off the mains with a stop-cock key. However, Spud has wandered into town and is curious when he finds the key. He turns it, and soaks Mr Bentley, who is supervising the job. Leaving his clipboard, Mr Bentley goes back to the Town Hall to change. Spud finds the clipboard and decides to become a building inspector. Meanwhile, Bob finishes the job and the hole in the road is cemented over. Mr Bentley returns to discover his clipboard gone. He and Bob go off to find it, following a trail of 'building certificates' which Spud has left. They eventually catch up with him back at the site of the burst pipe, but so keen was Spud to inspect Bob's work that he has become stuck in the cement. Bob rescues him and Farmer Pickles takes him off to give his feet a good wash.
