Water Pressure Reducing
Valve (WPRV), what
comes with it?
The X65B is marketed in three different

as a Rough-in-Kit, or you may purchase
the Cartridge Assembly separately and
install it at the finish plumbing stage to
complete the pressure reducing valve
installation.
How does the X65B
Cartridge Assembly
work?
The X65B factory preset Cartridge
Assembly is a complete module that is
installed, typically during final plumbing
work, or it can be installed as a com-
plete replacement if any required service
needed—no tools are required.
Can the Cartridge
Assembly be removed?
The Cartridge Assembly can be easily
removed, if required, by turning the unit
counterclockwise—no tools are required.
Note that water supply needs to be
turned off prior to any performance of
maintenance.
Should the Cartridge
Assembly be disassem-
bled?

When
I order
a X65B
Rough-In-
Kit, what
comes with
it?
The Rough-In-
Kit consists of
the valve
bronze
body and
the plastic
strainer/
cap.
When is the
Rough-In Kit
used?
The Rough-In Kit can
be used in the initial
construction stage. The kit
body is installed permanently into the
water system eliminating material and
labor costs for jumper kits. The unique
strainer/cap assembly is used until the
finish plumbing stage. At that point, it
is replaced with a permanent Cartridge
Assembly.
What kind of end con-
nections (tailpieces) are
available on the X65B
WPRV?
The X65B can be supplied with the fol-
lowing end connections: either single
union or double union, threaded, solder,
Quick-Connect, PEX and CPVC.
May I order end
connections (tailpieces)
separately for the X65B
WPRV?
Yes, end connections are available sepa-
rately in a polypropylene bag consisting
of a union nut, end connection (tailpiece)
and O-ring. The TPK (tailpiece) kit will
allow for flexibility and lessen inventory
requirement.
