Hunter HCV Check Valve

An economical water-saver that eliminates low head drainage for sprinklers located on slopes

Low head drainage is a fact of life when dealing with variable elevation landscapes. Water will naturally settle to those low points of the system, resulting in unwanted puddles of wasted water. With Hunter’s new, easy to use HCV you won’t have to deal with this problem ever again. Made to last, the HCV is designed and built to schedule 80 specifications, ensuring a solid, long-life and dependable performance.

HCV Product Installation
  • Flush the system until water from lateral line runs clean.
  • Use only Teflon paste or tape on all threaded connections ( note: Do not use Pipe Dope or solvent cement on threaded connections.) Apply the Teflon around the male adapter or nipple threads, then insert it into the HCV. Tighten by hand and then using a wrench, turn the adapter/nipple 1/2 turn to ensure a good seal. Overtighting may break the valve.
  • Glue the male adapters to the pipe, or thread the nipple into the PVC fitting.
  • Connect either the spray head or rotor to the HCV also using Teflon paste or tape..

Adjustment of Check Height

Hunter manufactures the HCV with the check valve set to compensate for 12 feet of elevation change. However, the valve is designed to hold back varying amounts of water to accommodate changes of anywhere between 5 and 32 feet. Adjustements for different check heights can easily be made either with the sprinkler in place or before the sprinkler is installed.

  • Before Installation: Simply insert a large flat-head screw driver in the outlet side of the check valve and turn the plastic screw. Clockwise turns will increase the check height, counter-clockwise will reduce it.(the photo to the right shows how to adjust without the sprinkler installed.)

  • To adjust the check valve when the sprinkler is already in place: unthread the body cap, pull out the sprinkler’s internal parts, stick the screwdriver straight through body and the inlet, and you will get right to the adjustment on the check valve. If you have a check valve installed below ground, this eliminates the need to unthread the sprinkler should you want to adjust the check height at a later time. HCV
