Emma calls Lori to tell her the riding school is closed due to burst pipes in the stable yard. While Emma makes a jocular reference to the yard resembling an ice skating rink, her husband Derek's repair efforts are successful (since he rehabs buildings for a living), even uneventfully so.
Bree Pym foolishly repaints her bedroom during a cold snap and avoids opening the windows (and thereby bursting her pipes) by leaving the house closed up for several days. She does go back to check on the place and opens the windows for a short while in the daytime, but closes them again before nightfall.
Perfect Strangers had a memorable episode, entitled "Pipe Dreams", where Jennifer asks Larry to let the plumber in while she and Mary Ann are away on a flight, so he can replace the showerhead. Larry agrees but then immediately calls to cancel the plumber - against Balki's advice - saying he will do it himself, in order to impress Jennifer. After what Balki describes as "twenty-three hours of backbreaking labour" Balki and Larry turn on the new showerhead to test it: the showerhead flies off as a jet stream of water shoots out, the taps at the sink fly off the basin with their own water jets, the toilet erupts like Old Faithful and opening the cabinet results in a flood from the pipes. This episode was regarded by the cast, crew and fans as one of the funniest of the entire series.
A whole episode of The Golden Girls was devoted to them trying to renovate their own bathroom. One result is the shower turning on when they turned the tap over the handbasin.
In the first season of The Lucy Show Lucy and Vivian's attempts to install a shower have them filling up the entire stall with water and nearly drowning.
This wasn't a joke, Ms. Ball in truth nearly did drown, and it's to Vivian Vance's credit that not only did she rescue her fellow thespian while in character, but kept improvising lines until Lucy could get her breath back.
The Fresh Prince of Bel-Air: The family has a routine that involves precautions like a 3-minute shower limit for whenever Uncle Phil goes on one of these sprees, but eventually this time, Vivian has to resort to the Lysistrata Gambit to get him to call the plumber.
In one of the later seasons of Boy Meets World Corey and Topanga (now married) move into a tiny fleabag apartment with rusty pipes. This trope is averted as Corey is able to actually fix the pipes (even though he got hilariously wet and messy in the process.
In the aptly-named Buffy episode "Flooded," Buffy tightens a pipe with a wrench to stop a leak ... (pause for a moment) ... and then all the other pipes burst, effectively flooding the basement.
In the Frasier episode "Seat of Power," Martin makes fun of Frasier and Niles' lack of practical skills, so in an attempt to prove him wrong they try to fix Frasier's toilet, with foreseeable results. Even more Hilarity Ensues when they call in the plumbers, who turn out to be the bullies who tormented them in grade school.
Averted in the HGTV series Holmes on Homes. Mike only took on jobs that were screwed up by paid contractors.
Another HGTV show, Disaster DIY, has contractor Bryan Baeumler come in to fix DIY projects gone wrong.
Subverted on That '70s Show when Red and Eric try to fix the kitchen sink. Although they fail to fix the sink, they don't do any major damage and decide to just call a plumber to fix it.
Eric's World had a clever subversion when Eric and C.J. had to deal with a leaky faucet. Rather than try to fix it themselves, C.J. suggests they call a plumber. When Eric protests that it's the middle of the night and they won't be able to get a plumber this late, C.J. uses his trusty "Plumber's Signal" (essentially a Bat Signal with the image of a pipe wrench, rather than a bat) to call a plumber, who arrives less than ten seconds later.
One episode of Family Matters had Karl trying to install a second shower in the house. Before his wife finally convinced him to call a plumber, he had somehow gotten the bathroom set up so that you turn on the shower by turning off the sink (simply put, he placed the shower's faucet upstream from the tee that divided between sink and shower).
Hannah Montana: When Jackson learned how much plumbers usually charge for their work, he convinced his Dad to hire him for a smaller (but still big enough to convince Jackson) amount. Jackson's Dad was furious at the results and called a professional plumber. Surprisingly, the plumber concluded Jackson actually prevented something worse from happening and said Jackson could be a professional plumber.
In The Sims series, a Sim can try to fix their broken plumbing themselves instead of calling a repairman or telling the landlord, much like they can with appliances. Plumbing is safer. A broken computer or TV set can electrocute a Sim whose skill isn't high enough, whereas fixing a toilet or sink will only make a Sim dirty and angry (read: decrease their Comfort and Fun) and the thing is now likely to break again immediately after.
Similarly, Donald Duck has also fought his share of losing battles against the dreaded faucet.
The Popeye cartoon Plumbing is a Pipe has Popeye helping Olive fix her leaky plumbing when the plumber (Wimpy) takes too long to arrive. It goes as expected until Popeye eats his spinach and starts punching the gushing pipes so hard that they seal themselves, then lifts the house off its foundation and tips it over to pur the water out a window. Shortly afterward, Wimpy finally arrives and all the pipes burst open again.
In another Popeye cartoon, "Floor Flusher", Popeye and Bluto compete to fix Olive's plumbing but end up flooding her house.
Yet another cartoon, "Popeye's Pipe Dream" has Popeye's plumbing failure flooding an entire city, fortunately it was all a dream.
Ed, Edd n Eddy do this to Johnny 2x4's kitchen sink in "Rent-A-Ed", after Ed breaks it while looking for some dish soap.
The entire premise of the Rocko's Modern Life episode "Pipe Dreams", in which Rocko and Heffer try everything they can think of to unclog a toilet. It turns out there's a giant goldfish living in the septic tank.
Also in "Dear John", where Rocko tries to fix the kitchen, and ends up making a bathroom instead because that's all the author of the manual knew how to do.
