ASVF Anti-siphon Valve Operation Manual

For use with all standard sprinkler controllers with 24 volt
AC output. The DAS I ASVF valves are diaphragm anti­siphon valves with flow control and atmospheric vacuum
breaker.

NOTE: These Rain Bird valves are designed for use with
static water pressures of a MAXIMUM of 150 PSI. For higher

Anti-Siphon Valves for Backflow Prevention

The DAS/ASVF models meet or exceed most building code requirements for
connecting a sprinkler system to a city water supply.

These valves prevent the possibility of back siphoning of water from sprinkler
lines into the drinking water.

The anti-siphon valves must be installed at least 6 inches above the highest
sprinkler or elevated piping in the circuit to meet most codes, (See Diagram

1.)(Consult local building code.)

CAUTION: Do not use this anti-siphon valve as a main line backflow device, nor
as a master valve. It is not designed nor approved to be under constant water
pressure on both sides of valve. This valve must be operated continuously for
more than twelve (12) hours. Do not install any other valves down stream. If
installed incorrectly with constant pressure on both sides of valve, it is possible
the valve will fail or burst.

pressures, a pressure regulator should be installed. These
valves are for outdoor watering use only.

For dirty water systems-using wells, lakes, ditches, etc. for
yourwater supply, be sure to install a 100 mesh (or finer)
wire filter or screen filter before the electric valves. For use in
cold water less than 110°F (43.3°C), applications only.

How to Select the Right Valve Size

The valve size (3/4” or 1”) is determined by the water
flow (measured in gallons per minute, or GPM) of the
main line or the sprinkler circuit.

3/4” VALVES: 13 GPM or less.
1” VALVES: 14 GPM or more.

Assembly of Sprinkler Valves to Pipe

A sprinkler system is made up of one or more groups of
sprinklers (called circuits) each operated by its own con­trol valve. Study the illustrations and follow the instruc­tions for proper assembly.

1. Before connecting and testing the assembly, thor­oughly flush the main line to prevent debris from
damaging the valves.

2. On the inlet side of the control valve, use galvanized
steel pipe or thick-walled, Schedule 40 PVC, white
plastic pipe, as this pipe is under constant pressure.
On the outlet side of the control valve, thin-walled
PVC pipe or flexible polyethylene pipe may used.

1“ valves and pipes allow longer runs and more sprinkler
heads per circuit, as well as potentially reducing the total
number of valves required.

3. To assure a watertight connection, use only one to
two turns of Teflon tape on the threaded valve-to­pipe connections. DO NOT USE PIPE SOLVENT OR PIPE
DOPE. THIS MAY DAMAGE THE VALVE. DO NOT OVER­TIGHTEN. Screw adapters into place finger tight.
Tighten adapters one to two additional turns.

4. Install a master shutoff valve before all electric valves,
so that the water can be conveniently turned off if a
valve needs servicing.

5. When grouping valves, allow sufficient spacing
between valves to unscrew the valve from the pipe
(about 6 inches).

6. Do not connect the outlet side (piping to sprinkler
heads) without first testing for leaks. If the outlet side
is connected and there is a leak, the pipe would have
to be cut in order to tighten the connection.

Valve Operation

Your Rain Bird valve offers two features with which you
should become familiar.

FLOW CONTROL: This feature allows you to control the
amount of water going to your sprinklers. To allow more
water through the valve, turn the black knob counter­clockwise UNTIL RESISTANCE IS FELT. This is fully open
position.

To reduce the amount of water, turn the black knob
clockwise. If you keep turning, you can turn the valve all
the way off. In this case, the valve will not open.

MANUAL CONTROL: This allows you to override your
automatic controller and turn your sprinklers on AT THE
VALVE . The valve can be turned on manually with the
external bleed screw or with the internal solenoid bleed.
The solenoid (block cylinder with wires) is wired to your

4

controller and turns the valve off and on electronically.

To operate manually with the internal bleed, turn the
solenoid 1/4 turn counter-clockwise; this opens the valve.

The sprinklers will continue to run until you turn the
solenoid back in the clockwise direction (snugly), but do
not over-tighten.

To turn on (open) the valve with the external bleed, turn
the external bleed screw counter-clockwise, 1/2 turn.
Water will exit the external bleed while the valve is on. To
turn off the valve, turn the external bleed screw clockwise
until snug. Do not over-tighten.

TO OPERATE YOUR VALVE ELECTRONICALLY, BE SURE THE
SOLENOID IS TURNED ALL THE WAY TO THE CLOCKWISE
POSITION.

Connection, Testing and Wiring These Valves

1. Shut off the water main or the master shutoff valve

6. Each valve has two wires. Either one may be used as
and connect the valve or valve assembly to the main
supply pipe. Be sure the water lines are flushed and
clean.

2. Test the pipe and valve connections for water tight­ness as follows:

A. Turn the flow control clockwise (down) to off

before turning on the water supply.

B. Tum on the water and check for leaks.

3. Now complete the hookup by connecting the outlet
pipes from the valves to the sprinklers.

4. Set flow control adjustment before making wiring
connections.

5. WIRE CONNECTIONS (Diagram 2). Use 18 gauge
wire to connect the wires to the controller. Wiring
that is to be buried alongside the pipes should be
APPROVED for UNDERGROUND use. For all splices, use
water tight connectors. (Do not exceed 600 ft.)

the “HOT” wire which is connected directly to a sta­tion output terminal in the controller. The other wire
is “COMMON” and may be joined to the common
wires of other valves with one wire running to the
common terminal of the controller. Check operation
using the controller.

(with controller)

1. Incorrect controller setting (check length of run time)

2. Loose solenoid (should be tight)

3. Loose bleed screw - check and tighten (finger tight only)

4a. Diaphragm filter clogged. Use manual, external bleed to flush valve. If this does not improve

operation, remove top of valve (6 screws). Remove diaphragm and inspect filter for debris.
(Check 4b at the same time.) Clean diaphragm filter and reassemble valve.

4b. Diaphragm/valve seat fouled or damaged. Remove diaphragm and inspect diaphragm and

valve seat for damage or debris. Clean or replace diaphragm and reassemble valve.

1. Flow control turned off. Check by turning black knob counterclockwise until encountering
resistance. Do not force beyond point of resistance. Turn knob back clockwise, approximately
one half turn.

2. Water supply off at meter or system control shut-off. (Check this first by manually bleeding the
valve with either bleed screw or by turning solenoid counterclockwise).

3. Blocked ports. If valve will turn on with manual, external bleed screw but NOT by turning the
solenoid for internal bleed, remove the solenoid (rod check solenoid cavity for debris. Visually
check small square hole at edge of cavity and carefully run a straightened wire through the
center round hole to clear tube of possible debris. Take care not to scratch sides of center port
tube as any change in size can affect valve operation.

1. Controller settings incorrect. Check programming, start times, run times and day schedules.

2. If none of the valves are working, check the common (ground) wire for a tight connection or
damage. If only one or part of the valves do not work, check wiring for damage (staples, nails,
cracks) between controller and valve location.

3. Check all of reasons in Section B.

4. Faulty solenoid. Turn off water supply. Switch solenoid with one from a nearby operational
valve. If original valve works with second solenoid, replace original solenoid. (Install water­tight wire connections on all valves at this time to avoid future solenoid shorts and/or failures.)

5. Controller not supplying power to valve(s). Check fuse. If blown, replace fuse with same size.
(Do not change sizes. A different size fuse will damage controller during operation and will void
the warranty.) If fuse is OK, either use a volt/ohm meter to check controller output (24 VAC)
at each terminal screw (station/valve connection) OR disconnect an operating solenoid from a
valve and take it to the controller. Attach one wire to the “C” terminal (common/ground) and
attach the other wire to the station which is not working. Activate the controller in manual
start. The solenoid should click (pull the plunger up into the solenoid tube) and it may hum.

If nothing happens, (and the controller is still under warranty) you should either return your

controller to the store or call your installer. If it’s no longer under warranty, you will need to
purchase a new controller. Be sure to install water-tight connectors on your wiring and a surge
protector (if you live in areas highly prone to lightning). This will help to avoid future problems.
