Ball valve prior to pump intake on a pool is a manual shut-off type of valve placed on the suction line (typically from the skimmer or main drain) right before the water goes into the pool pump. Its basic purpose is to regulate, control, or totally shut off the water going to the pump.
Purpose of the Ball Valve Prior to Pump Intake:
Isolation during Maintenance
It enables you to shut off water flow so that you can safely remove or maintain the pump, clean the strainer basket, or make repairs without draining the pool or making a mess.
Flow Regulation
Although for throttling purposes not perfect (because ball valves are used primarily for on/off), it can control flow in some systems momentarily.
Priming Control
Assists in priming the pump by enabling you to regulate water entering the pump, particularly when you are having issues with air within the line or need to set up suction.
Safety & Protection
Avoids backflow or flooding during equipment maintenance or emergencies.
Why a Ball Valve?
Simple operation: Quarter-turn handle for quick on/off control.
Reliable seal: Provides a tight shut-off, reducing the risk of leaks or air entering the suction line.
Durability: Made from PVC or CPVC, resistant to pool chemicals and corrosion.

What else can I help you with?
Can a ball valve affect the inlet of water in a washing machine?
Yes ! If it is not fully open,or horizontal. Cheers.....Dave
What are those pools of balls called?
Ball Pools
What is the difference between an air valve and gate valve?
An air valve is a spring loaded plastic valve for ventilation. A gate valve is an old fashioned type of water valve where turning a handle lowers a blocking gate over the water inlet. Any sensible plumber now uses ball valves instead.
How do you disassemble a water valve?
By shutting off a valve before it before attempting any repairs then it would depend on what type of valve your talking about globe/ gate / ball as each one is totally different
Is a ball valve a regulating valve?
no
What's the difference between floating ball valve and fixed ball valve?
The ball ceramic valve evolved from the plug valve, in which there is a plug initially. The ball valves also can be divided into floating ball valve and fixed ball valve. The differences between floating ball valve and fixed ball valve are as follows. For the fixed ball valve, the ball is fixed and will not move even under pressure. There are floating valve seat to press the sing real tightly on the ball when suffering the media's pressure. Besides, the axletree is equipped with the stem connecting with the ball. The floating ball valve contains the ball floating inside. The structure is simple and has good tightness. When the media goes through, the pressure is passed into the seal rings, therefore the material of the seat rings should be well considered in design.
What is a ball valve?
A ball valve is a contrivance by which a ball, placed in a circular cup with a hole in a bottom, operates as a valve.
A ball valve is used for what?
A ball valve is used to turn water , gas or oil on and off.
What is the structure of a ball valve?
Ball valves are quarter-turn on/off devices. A pivoting ball in the center of the valve controls the flow of liquid or gas media. The pivoting ball is known as a rotary ball, and it is designed with a hole (a bore) in the center. A stem on the top of the ball rotates the ball to open or close the valve. D Chel Valves are the Top Ball Valve Manufacturer in India.
Is isolation valve similar to ball valve?
EXACTLY
How do you identify upstream end of a ball valve?
in open condition the valve handle lever indicates the upstream end of a ball valveANS 2 - Most ball valves where that matters will have an arrow embossed on the valve body. In the case of many ball valve flow direction is immaterial.
What is a ball cock?
The valve that shuts off the water in a toilet cistern is known as the ball-cock. It is operated by a hollow ball attached to an arm, once the ball floats to a certain level, the valve shuts off the water. This action prevents water flowing out of the over-flow pipe to the outside. The ball and valve is known as the ball-cock.
