related to valve installations. Plastic piping systems must be engineered, installed, operated
and maintained in accordance with accepted standards and procedures for plastic piping
systems. It is absolutely necessary that all design, installation, operation and maintenance
personnel be trained in proper handling, installation requirements and precautions for
installation and use of plastic piping systems before starting. Swing Check & Spring Check
Valves are designed for horizontal installations, but may be installed in up-fl ow only vertical
applications. Can be used with IPS sized plastic or metal pipe.
Check valves must
be installed with the
valve fl ow arrows
pointing in the
direction of fl ow. Do
not install upside down. A minimum of
10 pipe diameters should be maintained
from any pump or turbulent source.
Piping system must be adequately thrust
blocked to prevent movement that could
pull pipe from end connectors.
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. All joining components must be clean.
STEP 1
PIPE CUTTING & DEBURRING Pipe ends must be cut square at 90° using a
wheel type cutter or a saw and miter box. Regardless of the cutting method used, burrs will be
created, which must be removed. A deburring tool is recommended, however a file or sand
paper may be used.
