Anti-Siphon Device

Your 700V Series pump comes from the factory anti-siphon
ready, easily allowing you to install an anti-siphon tube back
to the tank. An anti-siphon device (sometimes called a
vacuum breaker) is important because it will break a liquid
siphon if there is an open nozzle or a leaking hose below the
fluid level in the tank when the pump is turned off. Fill-Rite
recommends that an anti-siphon tube be installed from the
pump outlet back to the vapor space in the tank using kit #
KIT700AS.
The accompanying illustration shows where and how to install
the tube so that it terminates in the vapor space at the top of
the tank. The tube must terminate in the vapor space; if it
terminates below the fluid level in the tank, it will not prevent
siphoning. It is also very important that there are no liquid
traps in the tubing. The tubing must have a continuous slope
from the pump down to the tank, and can be connected into
any opening in the top of the tank if the tank adapter is not
used. Use reducer bushings as required for proper fit and seal.
Anti-Siphon line installed.
We recommend using the anti-
siphon tank adapter with a ¼
NPT opening in the side of the
hex portion. This opening
terminates in the vapor space of the tank. Make a liquid-tight connection using the
appropriate sealant from the adapter to the anti-siphon outlet using a minimum of 1/4 metal
tubing that is compatible with whatever liquid is being pumped. If the anti-siphon tank adapter
is being used and the ¼ NPT opening is not used for the tubing, leave the factory installed
plug in place.
Fill-Rite offers Anti-Siphon kit # KIT700AS (available through your Fill-Rite distributor). This
kit contains the necessary fittings and tubing to complete the installation as pictured in this
section.
WARNING! Threaded pipe joints and connections should be sealed with the
appropriate sealant or sealant tape to minimize the possibility of leaks.
