Any irrigation system designed or used for the application of fertilizers, pesticides, or chemicals, shall be equipped with an anti-syphon device consisting of the following components:
(a) Functional Check Valve. Such valve shall
be equipped with replaceable disc and shall be serviceable with conventional
tools. This valve shall be located in the irrigation supply line between the
irrigation pump and the point of injection of fertilizer, pesticide or
chemical. This valve, when installed, shall be on a horizontal plane and
level.
(b) Low Pressure Drain. Such
drain shall be at least three-fourths inch in diameter. It shall be located on
the bottom of the horizontal pipe between the functional check valve and the
irrigation pump. It must be level and must not extend beyond the inside surface
of the bottom of the pipe. The outside opening of the drain shall be at least
two (2) inches above grade.
(c)
Vacuum Relief Valve. The low pressure drain shall include a vacuum relief valve
as a component part, or shall be complemented with a separate vacuum relief
valve. The separate vacuum relief valve shall be at least three fourths inch in
diameter and shall be located at the top of the same horizontal pipe section in
which the low-pressure drain is located.
(d) Neither the low-pressure drain nor the
vacuum relief valve shall be altered in any manner, including the installation
of a gate valve or other device, which would render the anti-syphon system
inoperative or ineffective or permit it to be made inoperative or
ineffective.
