QUIET CHECK VALVE
Installation Instructions
QCV-3A-0210
Spears Quiet Check Valve has been designed to provide quiet operation
®
in sump pump or sewage ejector pump systems typically found in home
basements. The backfl ow of the water column in the discharge pipe can
slam conventional check valves closed, producing a disturbing "thump"
when the pump shuts off. The Quiet Check Valve uses a spring controlled
rate of closing to prevent slamming and eliminates the noise.
Produced in both 1-1/2" and 2" sizes, the 2" size is the minimum recommended
for a sewage discharge system (i.e., sewage ejector pump) while 1-1/2"
size can be used in an effl uent system (i.e., sump pump) discharge line
to prevent backfl ow of liquid into sump basin. The check valve should be
installed 12–18" above the pump discharge, or as recommended by pump
system manufacturer. Be sure check valve installation complies with local
codes.
Each Spears Quiet Check Valve contains both regular socket ends for direct
®
solvent cement connection of the valve and True Union style end connectors
for easy valve removal or replacement.
The Quiet Check Valve may be installed in either horizontal or vertical position.
Check pump system manufacturer's recommendations for horizontal,
vertical or angled positioning of check valve. In horizontal installations, orient
valve according to marking for best operation. In all

installations, valve MUST be installed in proper fl ow direction as indicated by
the fl ow arrow on body.
Read all applicable instructions and procedures thoroughly before starting.
Suitability of the intended service application must be determined prior to
installation

SOLVENT CEMENT APPLICATION
For best results, installation must be made at temperatures between 40°F
and 110°F. All joint components must be inspected for any breaking,
chipping, gouging or other visible damage before proceeding. All pipe,
fi ttings and valves must be removed from their packaging or containers and
exposed to the installation environment for a minimum of one hour in order
to thermally balance all components. Apply Primer and Solvent Cement with
an applicator no less than 1/2 the pipe diameter. All joining components must
be clean and dry.
