John is a plumber who is looking for love. He's looking in the house of the blonde Jane who has daddy issues. He's always been pretty successful before. And this situation looks to be one where John will be able to lay some pipe and unclog some stuffed passages.
Plumbers Don't Wear Ties is an "interactive story" dating simulation. After a video introduction, Players are treated to photographs of various people and places while characters voice act the situation. At times, John will be able to make a choice of his next action, from a list of choices at key locations in the plot. If John is successful, he'll move into an amorous relationship with Jane. If not, the two will be pulled apart.
Despite being advertised as a full motion video game the game is only still pictures.
A secret code allowed the player to see some nudity (John's butt and Jane's side boob) during the shower sequences. Without the code, these parts of the body are covered with on-screen censorship icons. The PC version is uncensored by default.
A PC version was reviewed by some magazines, including PC Gamer UK (3%), but it never surfaced. In 2017 the YouTube user psychoticgiraffe found a copy of the Windows 3.1 version in a library (Indiana) and released it online. It has the copyright year 1993, higher audio quality and does not include the video introduction by Jane.
