These one-piece waterfall spillways are ideal for creating pondless style water features. While the CF12E features a single inlet, most models feature dual inlets for easy plumbing into either end. A plug is included to block the unused side (although both may be used). A 4" diffuser tube lays across the bottom of the spillway between the inlet fittings, so water enters from one or both sides and spreads out evenly across width of spillway, creating a smooth waterfall. Gravel can be used to fill the inside of the spillway creating a natural, even looking waterfall.
CF12E has one centered 1-1/2" inlet (pre-installed)
Other models have dual inlets 2" spinwelds (pre-installed)
