| − | A variety of {{w|Tap (valve)#Nomenclature|faucet}} controls have been designed for the control of a shower or sink's water output; however, Randall seems to find all the existing options to be inadequate in some way and posits in this comic that designers share a desire to create a more ideal design. The comic shows one such designer, looking unkempt and rambling like a madman as he explains to an off-screen character how his new faucet design works. The off-screen character promptly tells him that he should get some sleep, a request which the designer ignores in favor of continuing the search for the "perfect" water faucet.
| + | In general, a faucet's output has two independent parameters: flow velocity and temperature; some particularly frustrating faucet controls only offer one degree of freedom which simultaneously turns up the flow rate and the temperature, and thus cannot fully explore the shower-space (making it sometimes difficult to find a comfortable setting). Some faucets can adjust both parameters but only have a single lever which must be angled along degrees of freedom which are not always labeled clearly, and this may also irk Randall. Other faucets have two independent controls for the flow of cold water and hot water, however while these are highly granular, it can be difficult to adjust the parameters independently e.g. change the temperature without changing the flow, or changing the flow without changing the temperature. |

| − | In general, a faucet's output has two independent parameters: flow velocity and temperature; some particularly frustrating faucet controls only offer one degree of freedom which simultaneously turns up the flow rate and the temperature, and thus cannot fully explore the shower-space (making it sometimes difficult to find a comfortable setting). Some faucets can adjust both parameters but only have a single lever which must be angled along degrees of freedom which are not always labeled clearly or intuitively, and this may also irk Randall. Other faucets have two independent controls for the flow of cold water and hot water; however, while these are highly granular, it can be difficult to adjust the parameters independently e.g. change the temperature without changing the flow, or changing the flow without changing the temperature.
| + | While two-handle faucets may seem simple in the abstract, they are imperfect in practice. In older houses or those with hot water systems based on tankless or instant hot water heaters, the hot water pressure is rarely the same as the cold water pressure. This can cause problems with cold water flowing back into the hot line, creating temperature drifts, unexpected changes in temperature based on slight input changes, and non-reproducibility in shower settings. |

This can cause problems with cold water flowing back into the hot line, creating temperature drifts, unexpected changes in temperature based on slight input changes, and non-reproducibility in shower settings.
| + | Newer systems include "Thermostatic Valves" which are designed to alleviate these problems; ideally, they contain one control for temperature and one for flow, which would seem to fit the "non-confusing" brief and solve Randall's problems. However, designing a system technically functional and making it intuitive (and making it work in practice for all water supply systems) is non-trivial, so Randall may have had trouble with even these faucets in the past. |

| + | The title text is a hyperbolic and slightly sarcastic explanation of the merits of a faucet system, presumably from the engineer who designed it. It describes that the user can identify an undesirable result, e.g. of scalding water, through a trial-and-error feedback loop. But, with a decidedly long delay in response time as the scalding (then non-scalding) mix works its way through the system, it means that they are left waiting for any adjustments made to prove themselves as useful (or not) whilst still experiencing the prior state of the water. |

| − | The experience of a shower being affected by a significant change in usage of water elsewhere in the building (a running washing machine clicking into or out of a rinse-cycle, or the sudden use of a flush-toilet) is a typical one in any place without deliberately over-engineered plumbing. Purpose built hotels ''may'' have an in-built degree of resilience of this kind, but over many temporary stay-overs by guests (each new set having to become familiar with the plumbing) will develop wear and tear that later guests will not be automatically aware of — including the gradual wearing off of the traditional red and blue arrows intended to show the polarity of hot-and-cold controls.

| | + | [A man with short, messy hair and a scuffed face stands in front of a whiteboard. He is holding a pen and sketching above his head height. On the whiteboard are various scribbles, pieces of illegible text, drawings of waves, arrows, and side views and cross sections of the faucet. In the centre of the whiteboard, drawn with soft, sketched lines is a faucet. It has a square base with a semicircle above. Attached to the semicircle is a tightly curled tube that curls twice. Below it is a box shape that dispenses water through a circle. On the floor around him is an upright can, 7 pieces of crumpled or ripped paper and one flat one.] |

His other empty hand is also held up above his head, possibly touching part of the sketch. On the whiteboard are various scribbles, pieces of illegible text, drawings of waves, arrows, and side views and cross sections of a faucet. In the center of the whiteboard, drawn with soft, sketched lines is the faucet, the designers empty hand is touching it. It has a vertical wall-mounted square base with a semicircle above. Attached to the semicircle is a tightly curled helical tube that curls twice, this is the one the designer is drawing on at the moment. Below it is a drawing of a spout with a stream of water going almost to the bottom of the board. On the floor around the designers feet is an upright beverage can, a large piece of crumpled paper, and 6 smaller pieces of crumpled or ripped paper and one larger flat piece of paper.
