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.
