4.0 Installation Note: Each Proco Series 700 ProFlex rubber check valve installation can be considered a major pipe installation and the same safety requirements as used in pipe contracting installations should be implemented. Each Proco Series 700 ProFlex rubber check valve regardless of size should be installed in the same manner. -

Page 12: Operation
ProFlex Series 700 Check Valves require little maintenance. Periodic inspections can ensure that the check valve will provide years of maintenance-free service. Check for cuts or gouges which can easily be repaired with a self-curing rubber compound (Contact Proco). Ensure that the bill section is free from any debris that may have been lodged in the bill. This will be the only areas of concern that require periodic inspection. -
