Figure 3. Typical Automatic Air Release Valve Installation
Connect the valve outlet to a bleed line which
slopes back to the wet well or sump. The bleed line
must be the same size as the outlet opening or
larger, depending on which Air Release Valve is be­
ing used. If piping is used for the bleed line, avoid
the use of elbows whenever possible.
NOTE
For multiple pump installations, it is recommended
that each Air Release Valve be fitted with an inde­
pendent bleeder line directed back to the wet well.
If multiple Air Release Valves are installed in a sys­
tem, do not direct bleeder lines to a common mani­
fold pipe. Contact your Gorman‐Rupp distributor or
the Gorman‐Rupp Company for information about
installation of an Automatic Air Release Valve for
your specific application.
