As you might guess from the title, this movie is about the adventures of a plumber's assistant. In real life it's not exactly a profession where you'd expect a lot of hot sex action, but, of course, it is in movies like this. Aside from the vaguely sexy, plumbing-related hijinks though, there's a genuine plot where our hero "Sid South" (Christopher Neil)owes serious gambling debts to a pair of hulking loan sharks, and gets mixed up with a recently-paroled convict (after he fixes the, um, plumbing of the man's wife)in trying to retrieve a golden toilet seat (or rather a toilet seat with stolen gold concealed in it). There's nothing wrong, of course, with a sex comedy having a plot per se, but this unfortunately is not a very funny one.
These "Adventures of" films are naturally a cheap knock-off of the then-popular "Confessions of" series of sex comedies with Robin Askwith. The whole series is a couple steps down from the genuinely entertaining "Confessions of" series, but this film is also another step or two down from the first film in the series "Adventures of a Taxi Driver". It's a conceit in these films that blue-collar slobs somehow get more sex action than rock stars. The problem is that Neil often acts like a whiny, spoiled rock star and quickly loses the every-man sympathy of the audience. In the opening scene, for instance, he wakes up in his grungy, vermin-infested flat with a pretty nice-looking girl (evidently a one-night stand), who unaccountably considers him to be some kind of catch. But he kicks her to the curb like he's Rod Stewart (actually he leaves her bare-assed naked on the curb after his motorbike rips her dress off).
Neil has zero charisma in his role, but most of the female characters don't really have roles at all. They're all pretty cute, but they put in little more than undraped cameos. Suzy Mandel, for instance, was such an appealing actress that she sometimes appeared on the posters of movies she wasn't even in (like the French film "Pussy Talk"). Later, she went to the US and ended up in a big-budget XXX film,but they actually let her use a body double for the XXX scenes. Anyway, she's pretty much wasted as one of a quartet of "tennis girls" who catch the protagonist after he decides to use the ladies' shower for no real reason while on a job (in real-life he'd probably be reported as a sex pervert, but of course that's not what happens here. . .). The only characters I liked were the male character actors like the two loan sharks and "Sid's" boss. Their lower-class Brit accents were often virtually unintelligible, but they were at least funny.
