As a minimum, a hot water cylinder needs an exhaust outlet. This guards against the cylinder boiling, and thus exploding if no relief were available.
The cylinder could boil if for example the thermostat failed to cut out. Or in the case of a direct flame water heater, the cylinder may boil in a quite ordinary course of events.
Some systems use a pressure relief valve for this important purpose, and simpler systems just use a tall standpipe whose top is higher than the local water pressure.

How does a sprinkler valve work to control the flow of water in a sprinkler system?
A sprinkler valve works by opening and closing to control the flow of water in a sprinkler system. When the valve is open, water is allowed to flow through the system and reach the sprinkler heads, which then spray water onto the desired area. When the valve is closed, water flow is stopped, preventing water from reaching the sprinkler heads. This allows for precise control over when and where water is distributed in the sprinkler system.
What is the function of a control valve in a sprinkler system?
A control valve in a sprinkler system regulates the flow of water to the sprinkler heads, allowing for precise control over the distribution of water and ensuring efficient operation of the system.
Is this volume of water fixed?
The volume of water in a system can change due to factors such as evaporation, precipitation, and water flow. So, it is not always fixed and can vary over time.
How do sprinkler valves work to control the flow of water in a sprinkler system?
Sprinkler valves work by opening and closing to regulate the flow of water in a sprinkler system. When the valve is open, water is allowed to flow through the pipes and out of the sprinkler heads, watering the designated area. When the valve is closed, water flow is stopped, preventing water from reaching the sprinkler heads. This control is typically achieved through the use of a solenoid that is activated by an electric signal, allowing for precise control over when and how much water is distributed.
What is quasi steady flow?
Quasi- steady flow is one type of transient flow. In the characterized by the absence of inertial or elastic effects on the flow behavior. In such a flow the variation of discharges and pressures with time is gradual and over short time intervals the flow appears to be steady. Typical examples are the drawdown of a reservoir or the variation in demand in water distribution system over a 24- hour period.
Whai is a flow regulating valve?
A valve (device) to regulate flow to prevent over loading a system
Are there months when no water flows over Victoria Falls?
The flow of water is continuous
Why does hot water tank spurt water out over flow valve?
an arm
What is the function of a water well pressure switch and how does it regulate the water flow in a well system?
A water well pressure switch controls the operation of the water pump in a well system. It monitors the water pressure in the system and turns the pump on and off to maintain a consistent pressure level. When the pressure drops below a certain point, the switch activates the pump to bring more water into the system. Once the pressure reaches a set level, the switch turns off the pump to prevent over-pressurization. This helps regulate the water flow in the well system and ensures a steady supply of water.
How do you shut off the heat from a boiler that provides heat and hot water?
Flow control valve that will over come stratification of hot water flowing through the system until a circulator comes on
Can you have to much water in your pool?
Yes, the pool can over-flow.
What causes water to flow over a dam?
when it rains alot
