The Plumber (1979) + Bonus [Re-UP]

''The Plumber'' which Mr. Weir wrote and directed, is both comedy and nightmare. It watches the title character arrive insolently at the household of two thin-skinned academic types who haven't summoned him, and follows the process by which he dismantles their bathroom and drives them half-mad. The story begins innocently enough - despite such ominous shots as that of the plumber's black-gloved hand pressing an elevator button - when this bedraggled longhair arrives at the door and persuades the young wife (Judy Morris) that her bathroom needs fixing. Soon, though, she suspects there may be something amiss. Strange noises are coming from the bathroom, the sound of someone singing. She begins to suspect the plumber may be taking a shower.
