JTV/AS
and JTV/ASF Series Anti-Siphon
Jar Top Sprinkler Valves
Rain Bird’s Jar-Top Anti-Siphon valves combine the
newest in Jar-Top technology with the reliability of anti-siphon
protection. The Jar-Top bonnet quickly screws on without
using any tools. This allows you to easily access the
diaphragm for effortless maintenance and cleaning.
Rain Bird manufactures only the highest quality Anti-Siphon
valves. Use Anti-Siphon valves in locations where the use
of a pressure vacuum breaker (PVB) or doublecheck valve is
not required by city codes. Check your local city codes to
determine what type of valves are required. Anti-Siphon valves
are installed above ground and will prevent back flow if
properly installed. Anti-Siphon valves should always be installed
at least 6” above the highest head on the valve line,
and should never have another valve installed further down
the line from the main valve. All of our Anti-Siphon valves
work with any standard sprinkler timer.
