innertube

An Inner-Tube is placed in the pressure tank and filled partially with air to keep the tank from becoming “waterlogged”. Over time water can leak into the pressure tank and replace the air that is needed to keep the system working but with the rubber tube the water is unable to fill the tank. Some systems use a “snifter valve” to replenish the lost air but with the tube there is no need for this valve.

 

 

 

 

 

brass swing

The first check valve is a Brass Swing Check Valve. Because water must close this valve and then the valve must open again with the force of gravity the valve must be able to swing down freely.

 

 

 

 

 

 

inline check valveThe Second Check Valve is made from PVC and is known as an In-Line Valve. This type of valve has a rubber washer on the inside that softens the sound when it is forced shut. A metal spring keep this valve closed when no pressure is forcing it open. Because the valve is attached from the middle of the component it can close with less movement than a Brass Swing Valve and this increases the efficiency of the pump.

 

 

 

 

ball valve

Ball Valves are on both sides of the pump to stop water or allow it to pass. The first valve can be adjusted slightly to alter the amount of water that is entering the pump. The second ball valve is used to control the output of the pump. On the delivery end, the ball valve is also used to slowly allow water to enter the pipe when the pump is first starting. Once the pump is running the valve can be opened to its full open position.

 

 

 

 

pvc union

PVC Unions are located on both sides of the pump. These can be used to remove the pump from the drive and delivery pipes. Two common uses for removing the pump are for cleaning and for relocating the pump.
