Choose Waterfall Location
Assemble Waterfall Plumbing
- The waterfall should be positioned so that the water flowing from it enters the pond opposite the skimmer to ensure proper water circulation. The waterfall is best positioned so that you can view it from the outdoor and indoor areas where you plan to enjoy your new water feature.
- You can position the waterfall right at the ponds edge or at the top of a stream.
Position Waterfall Box
- Your PondBuilder Crystal Falls Waterfall Box has one spinweld fitting, located on the side of the bottom of the box. Thread the PVC male adapter (included) into that spinweld (use the included Teflon® Tape on the threads first).
Hook-Up Flexible PVC Pipe
- Compact the area where the Waterfall Box will sit to prevent future settling. The Waterfall Box should sit level from side to side and should be tilted forward slightly (about 1/4 bubble on your level) to ensure that the water flows forward through the spillway.
- Using soil, backfill around both sides and the back of the Waterfall Box.
Attach Liner to Waterfall
- The Crystal Falls Waterfalls are plumbed to accept 1.5" Flexible PVC Pipe. We recommend using Flexible PVC pipe as it is flexible and easy to work with.
- Using PVC Primer & Cement, glue the flex pipe into the PVC male adapter.
Install Filter Media
- Bring the liner up to the face of the Waterfall Box and check the positioning of the liner against the Waterfall Box. Use the liner clips (included) to temporarily hold the liner to the box. The liner should follow the contours of the pond edge or stream and the face of the Waterfall Box. It is a good idea to leave a little slack in the liner where it transitions from the pond edge or stream to the face of the Waterfall Box. This will ensure that the weight of the rocks used in the waterfalls will not pull down on the liner once it is attached to the Waterfall Box.
- Kneel in front of the waterfall and have the following within reach: cordless screwdriver, 5/16" nut driver bit, waterfall weir (included), silicone (included), stainless steel screws (included), black screw caps (included), utility knife (with new blade), and a clean rag.
- While kneeling in front of the Waterfall Box, remove the liner clips and fold the liner back toward you leaving it to rest on your lap. Using the clean rag wipe down the face of the Waterfall Box around the area where silicone will be applied. Also clean the area on the liner that will be coming in contact with the area you cleaned on the Waterfall Box.
- Apply a bead of silicone along the sides and bottom of the opening on the face of the waterfall, keeping the silicone bead centered the entire way.
- Bring the liner back up into position against the face of the waterfall. Hold the liner in place again with the liner clips to help keep it from moving around as you prepare to attach the waterfall weir. Gently run your fingers along the liner over the area where you applied the silicone and flatten the bead out slightly. This will help ensure a more even distribution of the silicone as you compress it when you screw down the weir.
- Bring the waterfall weir into position. Once in position begin driving the stainless screws into place. Start with the top screw on the left and then right to first hold the weir in position. Continue driving screws into the remaining pilot holes on the weir with your next screw going into the middle hole on the weir.
- Carefully trim out the section of liner inside of the waterfall area to open the channel where the water will flow through.
- Use the remaining silicone to run an additional bead along the joint where the Waterfall Box, liner, and weir come together. Smooth out the bead using your finger.
- From inside the Waterfall Box, place a small amount of silicone to the end of each screw. Then place a black screw cap on each screw.
- Position the filter mat horizontally in the bottom of the Waterfall Box. The Crystal Fall Waterfalls include one white mat.
- Fill the media bag(s) with biological media (not included) and position on top of the filter mats. We recommend using Springflo Bio-Filter Media (#13852) in the media bag(s) of the Crystal Falls Waterfalls.
