FlowVis® - INSTRUCTION MANUAL
Page 4
The Virginia Graeme Baker Pool & Spa Act requires
that all public swimming pools & spas that have a
single main drain or multiple drains that are 3 feet
or less (center to center) from each other, be fi tted
with a backup anti-entrapment system. Such systems
include, but are not
limited to, SVRS and
Automatic Pump
Shut Off systems.
Special consideration must be made when installing
a FlowVis® to such applications. Several of these
systems do not allow the use of Check Valves. It is the
responsibility of the installer to make sure that the
requirements of the specifi c backup system in use are
maintained.
An optional non-sealing fl apper is available for
these installations.

instructions. When purchased as a complete Check Valve & Flow Meter combination, a
copy of these instructions will be included with the FlowVis® packaging. If a FlowVis®
retrofi t kit has been purchased, it is the installer’s responsibility to ensure that the Check
Valve has been installed correctly and does not violate any local or federal codes relating
to Check Valves.

APPLICATIONS
FlowVis® is specifi cally designed for use in fresh water applications (i.e., swimming
pools, spas, fountains, water features, etc). It is not suitable for applications that are
contaminated with debris of such a size that it would prevent the check valve fl apper
from fully seating against the valve body.
