Hayward WATERFALLS WFSD126 Manuel Du Propriétaire page 5

PUMP SIZING:
In general the waterfall requires .15 l/min per mm of width. For example, the 200 mm waterfall requires
approximately 30 Liters per minute to produce a wall of water. Ratios of flow apply, as can be seen on
chart on page 4.
PLUMBING CONNECTIONS:
The back of the Waterfall fitting is a 1 ½" US standard pipe socket.
The most common installation of the waterfall is utilizing the main pool pump. A three way valve is
installed as illustrated below.
NOTICE: Only filtered water should be used with this product. Clogging within the product can occur if
the water is not properly filtered.
For multiple waterfalls Hayward recommends that individual valves be installed to allow balance the flow.
Two pumps can be connected to multiple waterfall fittings: This is the recommended installation when
more than 1800mm of waterfall is installed.
NOTICE: Only filtered water should be used with this product. As noted in the figures above when a
separate pump is installed an additional properly sized filter is required between the pump and
the waterfall.
If waterfall flow rate exceeds more than 40% of the filtered flow, a separate pump and filter system are
recommended.
2" Plumbing or larger is recommended from the pump and filter to the waterfalls, if more than 1500mm of
waterfall length is installed.
