Function of Water Pressure tank and How its work ?

We always facing a problem of pressure of water flow in our home, you expect water to flow at a certain speed. Water pressure in the line causes that water to flow. The flow of water will be reduced by the usage of those who are living below in the 4 and 5 storey apartment. If your home is on city utilities, water pressure is controlled by the city. If your home is on a well, you require something to build that pressure and this is the reason of the pressure tank. The pressure tank in a water well system generates water pressure via using compressed air to bear down on the water. Due to this pressure, when we open the valve water is pushed out of the tank through the pipes in your home. When the water in the pressures tank drops below the required amount, a pressure switch is activated turning on the pump. Complete system include pressure pump, tank and pressure switch is what allows water to flow through your home. These are designed in such a way to act as reservoirs for the home and generally set to keep pressure within 20 pounds per square inch (PSI) of your starting and stopping parameters. When you are selecting a pressure tank you will need to know the gallons per minute. It’s also decrease instances of water hammer as they reduce air in the pipes and control the pressure of the water. Pressure tanks have been around for a long, long time and have naturally been installed on wells and whole-house rainwater catchments systems. The tanks hold water for instant use; consequently, there is no cover in turning on the tap and water coming out the spout as there would be through a standard pump. Together pressure sensitive pumps and pressure tanks work to achieve the same end - water at the tap when requisite.

How water pressure tanks work

When water is turned on at a fixture in the building, compressed air in the water tank acts like a spring: it pushes water out of the water tank and into the building water supply piping and thus water is sent on to the building plumbing fixtures. If many fixtures are being run at once in the building, or if the water flow rate produced by the pump and piping and controls is a modest one, the pump may run continuously all while the fixture is being operated. Because the tank acts as a reservoir, it allows water to be drawn from the tank without the pump cycling on and off each time the water is turned on. This ultimately protects and prolongs the lifespan of the pump. Since water leaves the water tank, water pressure in the tank drops. Since the water tank as well contains air, the air pressure drops too. In the tank water pressure and air pressure will be at the same psi.
