• The check valve is part of the chemical suction assembly and prevents water from flowing into the chemical supply.
  • Color-coded metering tips thread into the end of the check valve.
  • 1/4″ suction tubing slides over the check valve barb and the installed metering tip.
  • Spring-loaded check valves will keep the chemical tube primed better than check valves with free-floating ball internals.

Chemical Compatibility Notes

  • Chemical check valves need to be replaced occasionally, but consider an alternate seal or body material if you frequently need to replace the standard check valve on your unit.
  • Available with polypropylene body (standard) or stainless steel for extra durability.
  • Available with EPDM seals (standard) or Viton for products that are incompatible with EPDM.

IMPORTANT:  Refer to the parts diagram for your unit to confirm the correct check valve style.  If you are unsure, contact us to confirm which style is suitable for your unit.
