[[folder:Manhwa]]
* One ''Manhwa/OldMasterQ'' strip have Master Q and Q's rival, Chiu (living in different floors of an apartment) taking their showers at the same time, with both of them adjusting the water's temperature resulting in each other's water unexpectedly turning hot or cold. An angry Mr. Chiu decide to turn his water's temperature to the max, resulting in Master Q getting drenched in freezing-cold water; Master Q then retaliates by turning his water off. Cue the sound of screaming upstairs as Chiu gets hit by a boiling-hot shower.

TruthInTelevision as most shower valves mix hot and cold water to achieve the desired temperature, so anything that diverts either hot or cold water will result in a sharp temperature shift in the opposite direction. Note that this was always a regional trope as it depends upon the central water heater practice common in non-tropical Western plumbing design but not always found in other cultures. Rapidly becoming a bit of a DiscreditedTrope in RealLife since [[TechnologyMarchesOn the introduction of pressure-balanced shower valves specifically designed to prevent this from happening]] - the worst that's likely to happen is that the shower's water flow temporarily drops. Such "anti-scald" shower valves are even required by law in some places, especially in commercial buildings like apartments, hotels, and dormitories. Nevertheless, if you have the (mis)fortune of being in a house or building with old plumbing, this trope is still doable.
