WOODLAND HILLS, Ca. ?EUR??,,????'??? Valvette Systems Corporation, manufacturers of the ?EUR??,,????'??LittleValve?EUR??,,????'????????oe product line, announced that it received its final testing results from the Center for Irrigation Technology. The tests were conducted in December at the Center?EUR??,,????'???s facility on the campus of California State University in Fresno, California. The sixteen tests, taking a full day to run, demonstrated that LittleValve products contribute to significant savings in both labor and water when heading up new jobs or maintaining existing sprinkler heads. LittleValve sprinkler parts and under-the-head fittings provide individual on-off/flow control for pop-up spray heads and above-grade sprinklers of any type. The time and water savings are due to 1) the ability to shut down each sprinkler for nozzle or head cleaning or replacement while the system is running, 2) the full control the technician has over both the amount of water exiting each sprinkler and the amount being flushed during line and head cleaning operations, 3) the fact that pop-up risers stay in the ?EUR??,,????'??UP?EUR??,,????'??? position with the nozzle removed while the water is running, and 4) the inherent fact that Little Valve replacement pop-up risers emit 13% to 16% less water than do ordinary risers.
