To prevent stratification of the hot water molecules into the cooler water as heat goes to cold
A cold tap on a pipe refers to a connection point where a valve or fitting is installed to access the cold water supply within a plumbing system. It allows for the diversion or measurement of cold water flow, often used for maintenance, repairs, or to supply cold water to appliances and fixtures. Cold taps are typically found in residential and commercial plumbing systems for efficiency and convenience.
Your local building department and the Plumbing Code, a normal test for a water system is to prime the system at the pressure it will be running, as long as it's not above 80psi and checking for visible leaks and pressure drop or meter movement.
I had a similar problem on a brand new system and researched it. If it cycles when the cold water tap is on, see: http://uk.answers.yahoo.com/question/index?qid=20090809045527AAGRrZj If it cycles when the cold water is off, see: http://www.howtomendit.com/answers.php?id=264190

secondary cold water system
There are two pumps the primary and the secondary pump. The primary is the chilled water pump which is what pumps cold water throughout the building and the secondary circulates the water.
The cold water inlet in a water heater system brings in cold water from the main water supply into the tank, where it is heated up to provide hot water for household use.
The hot and cold water valves in a plumbing system control the flow of hot and cold water into the fixtures, allowing users to adjust the temperature of the water coming out of the taps or shower.
No, cold water is not always on the right. The location of hot and cold water taps can vary depending on the plumbing system and design of the fixture.
Your water may be cold due to a variety of reasons, such as a malfunctioning water heater, low water pressure, or a problem with the plumbing system. It is recommended to check these potential issues to determine the cause of the cold water.
Don't know how cold your cold is but, it could be water in the fuel system (ice).
Your cold water may be hot due to a malfunction in your water heater, where hot water is mixing with the cold water supply. This can happen if the water heater's thermostat is set too high or if there is a cross connection in the plumbing system.
A direct cold water system is a plumbing setup where cold water is supplied directly from the mains to the taps and appliances in a building without being stored in a tank. Two advantages of this system are that it provides instant access to cold water without the need for a storage tank, and it can be more energy-efficient as there is no heat loss from a tank. However, two disadvantages are that water pressure can vary depending on demand, and there is a risk of water contamination if there is a backflow issue in the mains supply.
A hot and cold mixing valve works by combining hot and cold water to achieve a desired temperature. The valve has two inputs for hot and cold water, and a single output that delivers water at the set temperature. By adjusting the proportions of hot and cold water flowing into the valve, the temperature of the output water can be controlled. This helps maintain a consistent and comfortable water temperature in the plumbing system.
To carry out a soundness test on a cold water system, you would typically isolate the system, fill it with water, and then pressurize it to a specific level using a pump. The system is then left under pressure for a designated time to observe if there are any leaks. If the pressure remains consistent, it indicates that the system is sound.
A hot and cold water mixing valve works by combining hot and cold water streams to achieve a desired temperature. The valve has internal components that adjust the flow of each stream to maintain the set temperature. By controlling the ratio of hot and cold water, the valve regulates the overall temperature of the water in the plumbing system.
