"Adventures of a Plumber's Mate" is definitely a cut above the average British sex comedy, and I realise that isn't saying much. Looking at the title you would expect a rip-off of those "Confessions" movies with Robin Askwith, and you wouldn't exactly be disappointed. The set-up is the same: a hapless young man with a working class job has a series of misadventures at work, usually involving loose women and their uptight husbands. There's a lot of nudity and low-brow humour, none of which is really funny, and silly accents and ridiculous characterisations.
However, there's quite a bit more going on in this movie than that. The movie is less episodic than those "Confessions" films, and all the other movies that came in its wake, with generic jobs in the title. The thing is this one has a plot about the protagonist trying to get out of debt that he owes to his landlord and a local bookie who has two henchmen after him. Although his forays into people's homes as a plumber are the typical sex comedy fare, what with women's dresses getting stuck in garbage disposal and torn off, leaving them naked, and a seductress handcuffing herself to the hero when her criminal husband is on his way home from the klink - the overarching narrative is more grounded in reality and thus feels a bit more relatable.
I enjoyed this movie - I say check it out.
