Installation Guidelines

Indoors

For indoor installation, make sure Series LF919-FS is accessible

to facilitate testing and servicing. Do not install the assembly

in a concealed location. If the location is parallel and close to

the wall, make sure the test cocks are accessible and the drain

line can discharge water if required. An air gap and drain line

are piped from the relief valve connection, allowing evidence of

discharge to be visible and preventing the occurrence of water

damage. (Refer to ES-AG/EL/TC at watts.com.)

Outdoor, Above Ground

For outdoor installations, install Series LF919 where there are no

freezing conditions and above ground whenever possible.

Install the assembly in an accessible location to facilitate test-

ing and servicing. The installation must also allow for adequate

drainage from the air gap and the discharge line if needed.

WARNING

Do not allow the drain line to empty directly into a drainage

ditch, sewer system, or sump.

Do not install the assembly in any location where any part of the

unit could become submerged in standing water.

Parallel

For parallel installations, two or more small-sized assemblies

can be installed (when approved) to serve a large supply pipe

main. Use this type of installation in an application where

increased capacity beyond that provided by a single valve is

required. Additionally, this type of installation permits testing

and/or servicing of a single valve without shutting down the

complete line.

The number of units installed in parallel should be determined

by the engineer’s judgment, based on the operating conditions

of a specific application.

NOTICE

The total capacity of all the units installed in the application

should equal or exceed that required by the system.

A. Shutoff Valves: If you remove the shutoff valves from the

assembly, reassemble the shutoff valve with the test cock

mounted on the inlet side of the unit.

B. Check state and local codes to ensure the assembly is

installed in compliance with the codes, such as proper

height above the ground.

C. Recommended: Install a strainer ahead of the assembly to

protect the internal components from unnecessary fouling.

CAUTION

Do not install the assembly with a strainer in rarely used

water lines, such as a fire sprinkler system which is only

deployed during emergencies.

Start Up: Close the downstream shutoff. Open the

upstream slowly and fill the valve. When the valve is filled,

open the downstream shutoff slowly, and fill the water sup-

ply system. This is necessary to avoid water hammer and/or

shock damage.

D. Vent the air gap and drain line from the relief valve in

accordance with code requirements. Terminate discharge

approximately 12" above the ground or through an air gap

piped to a floor drain.

WARNING

Do not allow the drain line to empty directly into a drainage

ditch, sewer system, or sump.

NOTICE

Relief Valve Discharge Rates. The air gap and drain line

terminating above a floor drain can accommodate any mod-

erate discharge or nuisance spitting through the relief valve.

However, to prevent water damage in the case of a cata-

strophic failure, design the floor drain size to accommodate

the increased discharge. (See table on typical flow rates as

sized by floor drain manufacturers, page 3.)

DRAFT

NOTICE

Do not reduce the size of the drain line from the air gap fit-

ting. The drain line must remain at full line size.

E. After the initial installation of the assembly, a discharge from

the relief valve may occur due to dirt and pipe compounds.

This may be caused by inadequate initial flushing of the pipe-

lines. If flushing the valve does not clear the unit, remove the

first check valve and clean thoroughly, using the procedures

in “Servicing the First and Second Check Valves.”

NOTICE

Periodic relief valve discharge may occur on dead end

service applications, such as boiler feed lines or cooling

tower makeup lines. This may be due to fluctuating supply

pressure during a static or no flow condition. To avoid this

discharge, install a spring-loaded, rubber seated check valve

ahead of the backflow assembly.

F. Avoid placing the assembly in a pit or at a depth below the

ground level, unless absolutely necessary. If an installa-

tion requires below ground level installation, a modified pit

installation is recommended, as well as the approval of local

codes. In such cases, provision should be made to always

vent the drain line above the flood level. In the case of a pit

drain, ensure an adequate air gap exists between the bottom

of the drain line and the bottom of the pit.

G. Periodically inspect the assembly to check for any discharge

from the relief valve. This discharge is a visual indication that

the valve needs cleaning or repair. Also test the valve peri-

odically in compliance with local codes to ensure its proper

operation.

The relief vent discharges water during no-flow periods in the

following instances:

• The first check valve is fouled.

• The inlet pressure to the check valve drops sufficiently due

to upstream pressure fluctuations. This affects the required

operating differential between the inlet pressure and the

reduced pressure zone.

• The second check is fouled during emergency backflow or

resulting from a water hammer condition.

For more information download Troubleshooting Guide S-TSG.

NOTICE

When installing the assembly on fire prevention systems, special

considerations are required.

Fire Protection System Installations: The National Fire Protection

Agency (NFPA) Guidelines require a confirming flow test to be

conducted by a certified tester whenever a “main line” valve is

installed, such as a shutoff valve or a backflow preventer.
