IF AN AUTOMATIC LINE
FLUSHING VALVE IS
NOT DESIRED:
• It is because holding the
water in the Techline CV is
desired and,
• Procedures have been
established to manually
flush the lines during the
season.
• In this case, Techline
Shut-Off Valves
(TLSOV) or
Figure 8 Line Ends (TLFIG8)
should be located along the
exhaust header, or at the
midpoint of a LITE layout.

Netafim Line Flushing Valve
IF AN AUTOMATIC
LINE FLUSHING VALVE IS
DESIRED:
• It is because the desire to have
a cleansing action outweighs the
desire to hold the water inside
the tubing when the zone is off.
• As such, place a Line Flushing
Valve (one per each 15 GPM
of zone flow) as far away from
the source as possible. This will
typically be somewhere along
the exhaust header in a GRID
layout and at the midpoint of the
tubing in a LITE layout.
• When Center Feed layouts are
used, install at least one Line
Flushing Valve on each exhaust
header.
• Line Flushing Valves should
be buried in a valve box with a
gravel sump adequate to drain
approximately one gallon of
water.
• See Air/Vacuum Relief Valves on
page 13.
