• The well level control valve is mounted on top of the two stage filter/regulator
assembly. It uses a well level sensor hose down well to sense the fluid level
in the well. It supplies air to the DDP when the fluid level rises and shuts the
DDP off when the fluid level recedes. (See Figure 1)

• The pneumatic sensor circuit has an air bubbler connected to the 1/4 inch
well level sensor hose via a quick connect. (See Figure 2)
System with Top Loading Cup:
