Need help?Do you have a question about the Atlantic PS3900 and is the answer not in the manual?
Calculate estimated water volume before construction and final water volume upon completion for a well-maintained water garden.
Determine pond surface area to calculate maximum surface area for waterfalls and streambeds to avoid pump issues.
Proper construction limits transitional water and ensures optimal system function by maintaining short distances between weir rock and liner.
Position skimmer and filterfalls across from each other to create a current that pulls surface debris into the skimmer.
Excavate a few inches wider and longer than the skimmer body, 15" below water level, on stable, compacted soil.
Hold liner against skimmer face, extend 2" above, clip in place, and cut hole for weir door using skimmer face as guide.
Insert weir door assembly, align holes, pierce liner, and loosely fasten corners before installing remaining screws.
Use molded step fittings for 1 1/2" or 2" PVC pipe; install TR215CV Triton Check Valve between pump and supply line.
Install bulkhead fitting and 1 1/2" MTA; reverse thread nut loosens clockwise, tightens counterclockwise.
Place FilterFalls on undisturbed soil or compact thoroughly if elevated; ensure it is level side-to-side and front-to-back.
Position liner, drape 6" over enclosure, use spring clips, cut spillway opening, apply silicone, and reattach clips.
Eco-Blox basins are 10% Eco-Blox/90% water; Gravel basins are 70% rock/30% water. Basin should hold 3x water volume of waterfalls/streambeds.
Calculate streambed volume by multiplying average length x width x depth in feet. Account for rock depth.
For Eco-Blox: cubic feet of streambed x 3 = cubic feet for basin. For Gravel: cubic feet of streambed x 9 = cubic feet for basin.
Dig area 22" deep for PV1700, 18" deep for Eco-Blox; place vault away from waterfall for easy lid access.
Use molded step fittings for 1 1/2" or 2" PVC pipe; flat panel on back is for overflow; drill points for Auto Fill.
Excavate basin at least twice the width of fountain pieces; dig basin down to 17" below grade.
Recessed panels accommodate Triton 3-Way Diverters; drill 2 1/2" hole for diverters; center area for 1 1/2" PVC pipe.
Place FastFalls on level undisturbed soil or compact area thoroughly; test placement for level side-to-side and front-to-back.
Hold liner against flat panel, leave slack below spinweld, cut spillway opening, apply silicone sealant.
Position rocks on sides, build up to lip, support weight of gravel/rocks; cover with soil and plants for a natural look.
Cut discharge pipe at 'perfect cut' mark; smooth end, clean fittings, apply PVC glue, and insert into check valve socket.
Drill 1/2" hole for Auto Fill; insert with gasket inside, retaining nut outside; tighten snug. Connect to water source.
Drill 3" hole for bulkhead fitting on back of skimmer/vault; install bulkhead, MTA, and connect overflow pipe.
