Non-shock valves manufactured from PVC Type I material
WATER HAMMER – NDS requires that all PVC plastic piping systems be designed and constructed to AVOID EXCESSIVE WATER
HAMMER. Water hammer can cause damage, and failure to pipe, valves, and fittings within the piping system. Not recommended in any
shock applications.
NDS DOES NOT RECOMMEND the use of thermoplastic piping products for systems to transport or store compressed air or gases, or
the testing of thermoplastic piping systems with compressed air or gases in above and below ground locations. The use of our product
in exposed, compressed air or gas systems automatically voids our warranty for such products and its use against our recommendations
is entirely the responsibility and liability of the installer. NDS will not accept responsibility for damage or impairment of its products, or
other consequential or incidental damages caused by misapplication, incorrect assembly, and/or exposure to harmful substances or
conditions. See warranty on inside back cover.
Check valves may be suitable for usage on grinder pump installations, provided the maximum recommended flow velocities through
Flow Management plastic valves are not exceeded, the grinder pump system is inspected for proper usage, and on a preventative
maintenance schedule. Note that excessive chemical contact and backpressure will cause the check valve gasket to deteriorate at a
premature rate. Also, placing the check valve horizontal or at a 45° angle, instead of a vertical position, is recommended. Please follow
local code guidelines.
