Build a Backyard Waterfall Fast With the EasyPro JAF16W Just-A-Falls Kit

Dreaming of a real waterfall in your yard but dreading the guesswork of sourcing every part yourself? This all-in-one kit hands you everything for a 16-foot stream flowing over a 23-inch spillway, so you spend your weekend building beauty instead of chasing components. Just dig, assemble, and watch the water fall.

  • Stream size: 16' stream flowing over a 23" spillway.
  • Liner: DuraLiner™ 45 mil EPDM rubber with underlayment, sized 7' x 20' for the stream and 10' x 12' for the reservoir.

  • Pump system: TH250 submersible pump housed in the JAFM vault, connected with a 2" x 25' flex pipe.
  • Reservoir support: Five HSC44 Res-Cubes hold water and support the vault in a 5' x 5' x 2' reservoir.
  • Structural base: PRO-Blox™ add a stable foundation beneath the rockwork for long-term durability.

The included UWD23 Waterfall Diffuser spreads incoming water across the full width of your spillway. That means a consistent sheet of water tumbling over your rocks instead of an uneven trickle. The result is the natural, professional look you picture when you imagine a backyard cascade.

Weather-Resistant EPDM Liner in the EasyPro JAF16W Pro-Series Waterfall Kit

Water features live and die by their liner. This kit uses DuraLiner™ 45 mil EPDM rubber, a flexible and weather-resistant material that molds to the shape of your stream and reservoir. The matched liner sizes make layout straightforward:

  • Stream Liner Size: 7' x 20'
  • Reservoir Liner Size: 10' x 12'
  • Included underlayment cushions the rubber against rocks and roots

Reliable Pumping Power Behind the EasyPro JAF16W Waterfall Kit

At the heart of the system sits the TH250 submersible pump, housed in the JAFM pump vault and connected through the pump discharge assembly and 2" x 25' flex pipe. The vault keeps the pump protected and accessible, while the five HSC44 Res-Cubes hold water in the reservoir and support the vault so your stream keeps circulating cleanly.

Sturdy PRO-Blox™ Support Behind the Just-A-Falls Kit

The included PRO-Blox™ give your waterfall a solid foundation, helping hold shape and structure beneath your rockwork. Paired with the reservoir sized at 5' x 5' x 2', you get a stable base that stands up to years of running water. Want a custom stream length instead of the standard 16 feet?
