TYPICAL VACUUM BREAKER / ANTI-SIPHON SYSTEM
INSTALLATION NOTES:
1.
The purpose of the vacuum breaker/anti-siphon (also called a drain-back dam), is to
retain water in the header system during shut-down, and to eliminate air purge and shock
to plumbing during start-up.
2.
It is necessary to duplicate this arrangement on both the supply and return lines.
3.
The drain-down valve allows header drainage for system maintenance and is closed
during normal operation.
4.
The vacuum breaker must be located at the highest point in the system, nearest to the
tank to be most effective. A nipple length of 8 inches minimum is required to create
sufficient vacuum to open the Cash Acme model VR-801.
