Description
Deliver a uniform sheeting effect across an 18" span with no moving parts to service. A common guideline is ~1–1.25 GPM per inch; use a valve to fine-tune flow for even edge-to-edge sheeting.
Pro Tip
Balance the line at start-up using a dedicated valve. Minor adjustments greatly improve uniformity across the lip.
Installation Tips
Mount level with continuous weir support. Verify inlet size/orientation before rough-in. Provide serviceable flow control and follow waterproofing best practices on the wall face.
