Description
ARG 18″ Waterfall, 1″ Lip, Back PortClear
18″ clear waterfall with a 1″ lip and rear feed for hidden plumbing. Durable PVC; plan about 18 GPM for a full sheet. SKU WF1801ACL.
Features
- Smooth, sheeting cascade from a discreet 1″ lip.
- Back-port feed keeps the wall face clean.
- Clear PVC body complements tile and stone finishes.
Deliver a crisp water line on raised walls and spillways. The 18″ width works as a single feature or in multi-unit arrays. As a general guideline for sheer descents, plan roughly 1 GPM per inch and trim with a valve for an even sheet.
Pro Tip
Use a dedicated valve to balance flow during start-up. Slight adjustments noticeably improve edge-to-edge uniformity across the 18″ lip.
Installation Tips
Mount level with uniform weir support. Verify inlet size/orientation before rough-in. Provide a serviceable valve for flow control and follow waterproofing best practices.
