8. ANTI-SIPHON VALVE INSTALLATION
Operating pressure: 20-150 PSI
Recommended operating pressure: 10-80 PSI
The 710A-ASV controller can be installed directly to PVC
pipe with two PVC male adapters (not included). Inlet 3⁄4″
FNPT, outlet 3⁄4″ FNPT.
NOTE: The 710A-ASV or 710A-011 must be installed at least
6″ higher than the highest sprinkler head on the system or
back-drainage may occur. Additional control valves must not
be installed downstream of the anti-siphon valve. The valve
must not be operated continuously for more than 12 hours in
any
24-hour period.
Consult local codes for specific details.
1. Flush main line until water runs clear before installation.
2. Shut off main water supply.
3. Install the anti-siphon valve directly to PVC pipe using 3⁄4″
PVC male adapters (Figure H and I) or use 3/4″ schedule
80 nipple. The arrow on valve body indicates direction of
water flow. (Figure I)
NOTE: Wrap all fittings with Teflon tape. Do not use pipe
cement on the valve as this will damage the valve and void
the warranty.
Make sure when wrapping fittings with Teflon tape that no excess gets into the
internal assembly. Tighten the fittings with
a wrench, but do not over tighten.
4. Turn the main water supply on and pressurize the system.
