120 degrees. Anything higher is a code violation and the plumber could be liable under local laws.
Correct Answer is as followsWhen I work as an expert witness I ask "what is the water being used for"
Most inept people will pick a number out of the air and swear it is gospel, BUT in reality a Master plumber or Plumbing engineer will get the facts before spewing temperatures. ( I Never lost a case in 26 YEARS of testifying )
For example for nursery schools or were the elderly are going to use the fixture the temperature shall not exceed 105 DEG F
In a commercial application the water temperature shall be 160 -180 DEG F in lieu of chemicals for sterilization
Water @ 120 degree's F will not kill bacteria and can actually lead to water borne diseases to incubate inside a heater that is set so dangerously low.
Knowing the facts then giving an answer goes a long way rather then taking a shot in the dark.
Ideally a legitimate Master plumber may suggest a heater capable of putting out 140 degrees F (non commercial) and have this water go to dishwashers and washing machines to make sure bacteria is killed inside the supply piping to the appliances / fixtures
Then install a decent quality tempering valve and temperature pressure regulated faucet /shower body to prevent scalding.
Also when quoting a "code" it is nice to know which code as there are board of health codes , ADA codes, plumbing "codes" and applications that require someone to think out side the box
water
A person can find and download the game Plumber for free, with no time limits from the Google apps play store. Plumber is a game where you turn the pipes to make sure the water goes through without leaking.
Water don't turn instantly into ice; this depends on the temperature.
The boiling point is the temperature at which water turns into a gas.
Water can evaporate no matter what temperature it is. It has a higher rate of vaporization at higher temperature however.
it means that you need to clean your sink if you have already cleaned your sink i recommend getting a plumber
Since the water is at a higher temperature than the ice, it transfers heat to the ice. This in turn raises the ice's temperature above its melting point of 32oF which turns the ice to water.
heating of water by the sun's energy which increases the temperature of the water causing some of the water to turn into water vapour at a temperature below the water's boiling point temperature.
Decrease the temperature and make it turn into ice.
Yes. Every solid has a melting temperature above which (hotter) it is a liquid and beneath which (colder) it is a solid. Answer For example, water becomes ice at zero degrees Celsius / 32 degrees Fahrenheit. That temperature is the melting temperature for ice. Hotter than that temperature will turn ice into water, and colder than that temperature will turn water into ice. 0 degrees Celsius is also called the triple point because water, ice, and water vapor can all exist at that temperature without changing their forms. In other words, at that temperature, ice can stay ice, water can stay water, and water vapor can stay water vapor.
100 degrees Celsius
You don't decrease the temperature, you raise the water's boiling point, or increase the water's temperature......
