Figure 6. Typical Automatic Air Release Valve Installation

The valve inlet line must be installed between the
pump discharge port and the non-pressurized side
of the discharge check valve. The valve inlet is at
the large end of the valve body, and is provided
with standard 1 inch NPT pipe threads.

The valve outlet is located at the opposite end of
the valve, and is also equipped with standard 1
inch NPT pipe threads. The outlet should be con-
nected to a bleed line which slopes back to the wet
well or sump. The bleed line must be the same size
as the inlet piping, or larger. If piping is used for the
bleed line, avoid the use of elbows whenever pos-
sible.

NOTE

It is recommended that each Air Release Valve be

fitted with an independent bleeder line directed
back to the wet well. However, if multiple Air Re-
lease Valves are installed in a system, the bleeder
lines may be directed to a common manifold pipe.
Contact your Gorman-Rupp distributor or the Gor-
man-Rupp Company for information about installa-
tion of an Automatic Air Release Valve for your spe-
cific application.

ALIGNMENT

The alignment of the pump and the engine is criti-
cal for trouble-free mechanical operation. See Sec-
tion E, Securing Intermediate And Drive Assem-
bly To Engine for detailed information.
