Jobe Rojo 1/2" Partfill is a low-flow valve intended for use in rainwater harvesting tanks. The purpose of the float valve is to automatically maintain a low level of water in the tank during periods of no or low rainfall. This allows services fed by the tank to continue while leaving capacity in the tank for refilling by the next rain.

• Pressure range 0-150 PSI
• Flow Rate - 5-6 GPM

APPLICATIONS:

Maintaining water levels in:

• Rainwater harvesting tanks
• Water Cisterns
• Irrigation and process applications

TIP: WHEN INSTALLING - be sure to flush the waterline before installing the valve to prevent debris from accumulating in the valve.

OUTLINE OF OPERATION

• The valve is installed through the side wall of a storage tank. It should be mounted above the overflow level of the tank to prevent backflow.
• As the tank empties, the weighted float travels down the cord and sits on the bottom stop to activate the valve.
• The valve will run until the weighted float lifts clear of the bottom stop.
• The float will then rise as rainwater fills the tank and falls as the tank water is used.
• The valve will only function at times when rain fall is insufficient to maintain a water level in the tank above the bottom stop.
• The use of the flow restrictor before the valve will not cause the valve to malfunction.
