General Information
Backflow is defined as the reverse flow of a liquid into the potable water
supply. The installation of a backflow preventer protects the water supply from
contamination from this very serious condition. This product guide includes
information on Watts’ complete line of backflow prevention devices. Should
you require additional information, contact your local Watts Representative
listed on the back of this guide.
Code Requirements
All major plumbing code bodies address protection against backflow. All potential or
existing cross connections must be protected from backflow by the installation of a
proper backflow prevention device. Consult your national and local plumbing code
authorities for more specific information on your code requirements.
757 OSY
Backflow Definitions
Backpressure: pressure, higher than the supply pressure, caused by a pump, elevated tank,
boiler, or any other means that may cause backflow
Backsiphonage: backflow caused by negative or reduce pressure in the
supply piping
Cross-Connection: a connection or a potential connection between any part of the
potable water system and other environment containing substances in a manner that
under any circumstances would allow such a substance to enter the potable water
system. Other substances may be gases, liquids, or solids, such as chemicals, waste
products, steam, water from other sources (potable or non-potable) or any other matter that may change the color or add odor to the water. Bypass arrangements,
jumper connections, removable sections, swivel or changeover assemblies, or any
other temporary or permanent connecting arrangement through which backflow may
occur are considered to be cross connections.
Health Hazard: a cross-connection or potential cross-connection involving any substance that could, if introduced into the potable water supply, cause death, illness, or
spread disease, or have a high probability of causing such effects
Non-Health Hazard: a cross-connection or potential cross-connection involving any
substance that generally would not be a health hazard but constitutes a nuisance or
would be aesthetically objectionable, if introduced into the potable water supply

Series 909 Reduced Pressure Zone Assemblies are designed to provide
superior cross-connection control protection of the potable water supply in
accordance with national plumbing codes and containment control for water
authority requirements. Series 909 can be utilized in a variety of installations, including health hazard cross-connections in plumbing systems or for
containment at the service line entrance. With its exclusive, design incorporating the patented “air-in/water-out” principle, it provides maximum relief
valve discharge during the emergency conditions of combined backsiphonage and back-pressure with both checks fouled. Series 909 is
furnished with full port, resilient seated and bronze ball valve shutoffs.
Sizes 3⁄4" and 1" (20, 25mm) shutoffs have tee handles.

Air Inlet
How it Operates
The unique relief valve construction incorporates two channels: one for air, one for
water. When the relief valve opens, as in
the accompanying air-in/water-out diagram,
the right-hand channel admits air to the
top of the reduced pressure zone, relieving
the zone vacuum. The channel on the left
then drains the zone to atmosphere.
Therefore, if both check valves foul, and
simultaneous negative supply and positive
back-pressure develop, the relief valve
uses the air-in/water-out principle to stop
potential backflow.

Relief Valve
909RPDA OSY
Series 909RPDA Reduced Pressure Detector Assemblies are designed exclusively
for use in accordance with water utility authority containment requirements on
health hazard applications. It is mandatory to prevent the reverse flow of fire protection system substances, i.e., glycerin wetting agents, stagnant water and water
of non-potable quality from being pumped or siphoned into the potable water line.
Benefits: Detects leaks. . . with emphasis on the cost of unaccountable water;
incorporates a meter which allow the water utility to:
• Detect leaks that historically create great annual cost due to waste.
• It provides a detection point for unauthorized use. It can help locate
illegal taps.
Pipe Line
Center
All sizes are standardly equipped with AWWA epoxy coated, UL/FM listed OSY
resilient seated gate valves, CFM (cubic feet per minute) or GPM (gallon per
minute) meter and ball type test cocks. A pressure differential relief valve is
located in a zone between the check valves.

How it Operates
water. When the relief vale opens, as in
the accompanying air-in/water-out diagram, the right-hand channel admits air
to the top of the reduced pressure zone,
relieving the zone vacuum. The channel
on the left then drains the zone to atmosphere. Therefore, if both check valves
foul, and simultaneous negative supply
and positive back pressure develops, the
relief valve uses the air-in/water-out principle to stop potential backflow.

9D
Dual Check Valves
Series 9D Backflow Preventer with Intermediate Atmospheric Vent is specially
made for smaller supply lines and ideally suited for laboratory equipment, processing tanks, sterilizers, dairy equipment and similar applications. It is particularly recommended for boiler feed lines to prevent backflow when supply
pressure falls below system pressure. 9D is suitable for use on hot or cold
water and can be used under continuous pressure. It features a primary check
valve utilizing a rubber disc seating against a mating rubber part to ensure tight
closing. A secondary check valve utilizes a rubber disc-to-metal seating. In the
event of fouling of the downstream check valve, leakage would be vented to
atmosphere through the vent port thereby safeguarding the potable water system.

Dual Check Valves
Series SD-2 and SD-3 Dual Check Valves are designed for the protection of the
water supply from carbon dioxide gas and carbonated water. These substances can flow from post-mix beverage systems and are very acidic. If acidic
water comes in contact with copper pipe, it will cause the leaching of copper
salts into the water supply and if ingested can cause nausea, abdominal pain,
and in some cases vomiting. SD-2 and SD-3 prevent the reverse flow of potentially contaminated water into the potable water supply due to back pressure
backflow and is used for continuous or intermittent pressure conditions. SD-2
and SD-3 are recommended for use on Post-Mix Carbonated Beverage
Equipment and dispensing equipment for tea and coffee.

Series PVS-1000 Pre-Engineered Valve Stations are custom configured water
flow control systems that are assembled from proven, reliable Watts components
to meet exacting project application requirements. Watts pre-engineered valve
stations are factory pre-assembled, tested and optionally certified by independent agencies to ensure flow performance for critical building demands.
Series BIC-1000
Backflow Irrigation Control Stations
BIC-1000
7
Series BIC-1000 Backflow Irrigation Control Stations combine the master valve,
regulator valve, backflow preventer, preload valve and high-pressure lockout
switch all in one easily located component. Constructed using best practice
design principles, these systems maximize operating performance and reduce
pipe breaks and leakage within the irrigation system. Watts BIC-1000 station
minimizes system-operating pressure during both the system operation as well
as when there is no flow to the system to reduce water line breaks, has a single
warranty policy and is pre-tested to ensure reliable operation "out of the crate".
Features
System Attributes
• Preload Pilot. The entire irrigation
pressure piping system is maintained
with a preload stand-by, field
adjustable, low pressure control valve.
This in combination with a higher set
point on the regulator and master
valve creates a buffer when turned on.
• High-Pressure Lockout Switch.
When high pressure is detected, the
switch will lock out the 24V circuit;
making the system inoperable until the
problem is addressed. This prevents
high pressure shock and water hammer when the system is allowed to
turn on.
60
• All components are flanged type, nut
and bolt modular design for easy
replacement.
• 24-hour monitoring system of the outlet pressure for excessive buildup
above set operating pressure.
• Water is conserved by reducing or
eliminating potential line breaks
caused by high pressure. The master
valve/regulator is installed at the backflow assembly which provides a shutoff and pressure control of the entire
system.
For additional information, request literature F-BIC-1000.
• All components are above ground level
on a stainless steel station
• Combines the Master Valve, Regulator
Valve, and Backflow Assembly in one
easily located component

Guide to Options
Hydrant Connections – HC
The hydrant connection option is designed to prevent backflow of contaminants from tank and truck filling operations. A fire hydrant should be considered an open conduit to the water supply system and as such should be protected from actual or potential cross-connections that can occur. While fire
hydrants are normally considered to be safety devices for fire fighting purposes, the growing use of them to supply water for construction sites, roadwork,
street cleaning equipment and hydroseeding, can lead to the possible contamination of the water supply.
Available on series: 2" (50mm) 007, 009, 909
Locking Ball Valve Handles – LH
8
The locking ball valve handles options is designed for use on fire protection
systems to prevent accidental closure of the shutoff valve. Locking ball valve
handles provide vandal resistance for outdoor installations and prevent the
removal of the stem nut and ball valve handle. These locks allow an assembly's
bypass valve to be locked in the open position to prevent isolation of the meter
and resultant theft of water.
Guide to Options
Available on 1⁄2" – 2" (15 - 50mm) series: 007, 009, 909
Internal Polymer Coating – PC
The internal polymer coating option provides extended corrosion protection on
sensitive sealing areas and machined surfaces. The coating ensures the
smooth operation of the sliding and moving parts and common problems such
as pitting, mineral build ups and galling are negligible even after lengthy periods in extremely corrosive water conditions.
Available on series: 007, 008, 009, 909
Elbow Fittings for 360° Rotation – AQT
The AQT elbow fittings for 360° rotation option allows the installer to pivot the
valve's inlet and outlet in the direction of the piping since often times they do
not align exactly. This option provides great flexibility to the installer and saves
space, time, materials and money.
Available on series: 009, 919
