Installation and Operation Manual
NOTE
A flow control valve must be plumbed in a
convenient location on the supply line for
regulation of the water supply to the unit. See
Figure 14.
4.3 Plumbing Multiple Units
Plumbing two or more Sheer Descent waterfalls
together is done in exactly the same way as the
installation procedure for a single unit, explained
previously, with the exception that additional two-way
valves are required for each Sheer Descent waterfall.
See Figure 15. The loop plumbing option can also be
used for two or more units. See Figure 16.

the Sheer Descent waterfall. A Jandy three-way valve
is suggested to be used as the “T” from the return line
of the pool to the Sheer Descent waterfall. A properly
plumbed valve in that position will allow full control of
the water to the Sheer Descent, as well as to the rest of
the pool. In most cases, this valve can be located after
the filter near the equipment pad. See Figure 13.
NOTE All water to the Sheer Descent must be filtered.
Those systems using a separate pump must
use our separate energy filter (p/n 3456) or
equivalent to prevent debris from entering the
Sheer Descent unit.
4.2 Plumbing a Single Unit
All back feed Sheer Descent waterfalls have the
equivalent of standard 1½ inch inside and 2 inches
outside pipe protruding from the back of the unit. For
waterfalls 1 through 8 feet in length, this fitting is
located in the center of the back of the waterfall.
Standard 1½ inch and 2 inch PVC fittings will glue
in and over the 1½ inch slip by 2 inch insert fitting
provided on all Sheer Descent waterfalls.
4.4 Cutting the Lip for Radius or Custom
Installations
The extended lip Sheer Descent waterfall can be custom
cut in the field to meet specific needs, such as radius,
irregular shapes, etc. In order to custom fit the waterfall,
carefully measure the amount of extended lip to be
