About this Product
The Jandy 1218003 Sheer Descent Waterfall produces a clear arc of water, projecting away from the pool wall. The Jandy 1218003 Sheer Descent Waterfall produces a wide range of water effects and can easily be adjusted to suit any mood or environment. The flow can be setup to create a range of effects from an almost silent, glass like sheet of water, to a rushing mountain spring waterfall.
The Jandy 1218003 Sheer Descent Waterfall produces the same effect as the standard one inch lip Sheer Descent Waterfall, but allow for installation of brick or stone on the face of the raised beam. The soft white and gray lip color waterfalls are easily cut in the field for custom radius curves. When extreme radius curves are required, a Super Radius waterfall must be special ordered from the factory. Metal finish radius falls and fiber ready falls cannot be cut in the field and must be ordered directly from the factory.
Any pool not square or rectangular in shape (i.e. circular and other unique shaped pools) requires Radius or Super Radius Sheer Descents, to enable greater customization for unusually shaped and designed pools. The specific waterfall must be cut to fit the shape of your pool, so that it blends to the shape and adds to the fantastic look of the area.
When ordering the waterfall, please make sure you choose the correct style, lip color, feed type and lip size for a proper display and fit for the waterfall to the pool. If ordering a Super Radius Cut, please choose whether the cut should be convex (outside) or concave (inside) and specify the dimension of the radius.

Questions & Answers
Can you show me the specs on this item and what size pump will it take to run it
This is information from the Jandy Sheer Descent's installation manual.
In most cases, a properly sized standard swimming pool pump will operate the Sheer Descent waterfall and filter the pool with little loss of total water turnover. As a general rule of thumb, the Sheer Descent waterfall requires approximately 12 gallons per minute per foot with little head loss. For a more dramatic effect, more water gallonage can be applied to project the waterfall further away from the wall. When plumbing multiple falls, add the total length of waterfalls together to determine GPM required. e.g. When plumbing two 6 foot units, you now have 12 feet of waterfall, which requires 144 gallons per minute.
For more information including a reference chart and sizing of dedicated waterfall pumps please refer to this Installation Manual (Click Here to View PDF). The information on pump sizing begins on page 10.
