Backflushing steps are basically the same for all sizes and styles of wastewater Air Release, Air and Vacuum and Combination
Valves but there are two ways to accomplish backflushing.
1. With clean water, that must be 15 PSI higher than the pressure in the force main, the valve may be flushed clean back into
the force main. Flush back into the force main by connecting hose C to valve D. Next open valve A and flush for 2-3 minutes
thru D. Next close D and switch hose C to E and flush for one minute. After flushing close valve A. Disconnect hose C and
vent pressure inside the Air Valve thru valve D. Next remove cover bolts (det 7.) remove top cover (det 2) for visual inspec -
tion and scrape out any grease. Use care to remove the cover and the cover gasket (det 3) may be re-used many times.
Reinstall cover (det. 2) and slowly open valve A.
2. With clean water that is not 15 psi higher pressure than the force main, backflush thru valve B into an atmospheric collection
tank. Follow the same procedure as above except close valve A and open valve B. After flushing remove cover to inspect
interior and replace cover same as above. Then close valve B, open valve A and the waste water valve is back in service.
