This is more than a TV joke. It’s a timeless lesson in marketing and gullibility. Del Boy tried to sell us the idea that any old water can be luxury. And people bought it—until they got sick.
It also shows the genius of John Sullivan, the writer. He took a simple scam and turned it into a riot. The dialogue is crisp, the physical comedy is gold, and the social commentary is sharp.
You can watch the episode on streaming services today. It’s still hilarious. The diarrhea jokes never age. Never.

Here’s a cracker: in one scene, Del Boy drinks his own product to prove it’s safe. He immediately belches and gets a funny look. That was a genuine reaction from actor David Jason. He actually burped on cue.
The episode features a running sight gag of people running to the toilet. You hear flushing sounds over and over. It’s juvenile. It’s brilliant.
And the name itself? “Peckham Spring.” It’s a pun on “Peckham” (a gritty London area) and “spring water” (which implies purity). The oxymoron is the joke. Peckham is anything but a spring.
