Aquascape Medium Pondless Waterfall Kit 16' Stream – Complete Backyard Waterfall System w/ AquaSurge 2000–4000 Pump (SKU 53039)

The 53039 includes: 22" Waterfall Spillway, Pondless Waterfall Vault, Five (5) AquaBlox® Small modules, AquaSurge 2000-4000 pump (SKU 45009, up to 3,947 GPH, 180–215W) with Smart Control Receiver, check valve assembly, 2"×25' flexible PVC pipe, 45-mil EPDM fish-safe liner 10'×20' (stream) and 10'×12' (reservoir) as separate pieces, 120 sq. ft. geotextile underlayment, (2) 1-Watt 12V LED lights, 60W Transformer with Photocell, 3-Way Splitter, 25' LVL Extension Cable, Automatic Dosing System with 32 fl. oz. Prevent for Fountains treatment, Welcome Kit, and Installation Kit (silicone, foam sealant, PVC cement).

Not included: Rocks, gravel, and boulders (locally sourced). GFCI outdoor electrical outlet (required — must be installed if not already present).

The AquaSurge 2000-4000 (SKU 45009) provides adjustable flow from 2,000–3,947 GPH via its asynchronous motor. The included Smart Control Receiver offers two control options:

• Aquascape Smart Control App (iOS/Android): Connect wirelessly for flow adjustment, automated scheduling, and remote control from anywhere.
• On-board controls: The integrated panel on the Smart Control Receiver lets you adjust flow directly — no smartphone required.

An optional Universal Remote (#45041, sold separately) provides button-based wireless control without a smartphone. The pump must be connected to a 120V GFCI-protected outdoor outlet. Cord length is 20 feet.

The 53039 includes two separate 45-mil EPDM fish-safe liner pieces:

• 10'×20' stream liner: Lines the waterfall channel and stream run from the spillway down to the reservoir transition zone.
• 10'×12' reservoir liner: Lines the underground AquaBlox basin where water is stored.

These two pieces overlap at the transition zone between stream and reservoir, creating a fully waterproof system. The 120 sq. ft. geotextile underlayment installs first beneath both liners to protect against punctures from sharp rocks or roots below grade.

Five Small AquaBlox modules interlock to form a structural underground reservoir with high void space — storing significantly more water per cubic foot of excavation than gravel. Advantages:

• No heavy stone to source, transport, or position in the basin
• The Pondless Waterfall Vault sits within the AquaBlox grid for easy pump access
• The structural grid supports the weight of surface rocks, gravel, and foot traffic
• Higher water capacity means longer run time between evaporation top-ups

Both kits are identical in every component except the pump. The decision comes down to desired flow volume and visual impact:

• AquaSurge 2000-4000 (53039 — this kit): Up to 3,947 GPH. Natural, moderate-flow stream aesthetic. App-controlled variable flow. Lower operating cost (180–215W). Asynchronous motor — not designed for solids handling. Best for most residential 16' installations.
• SLD 4000-7000 (53064): Up to 7,127 GPH — nearly double the flow. Dramatic, full-width waterfall display. Solids-handling motor (tolerates leaf fragments and small debris). App-controlled. Higher price and operating cost.

For most homeowners, the AquaSurge provides a visually full, natural-looking 16' stream at maximum flow. Choose the SLD if you want maximum visual impact and/or have a location with heavy leaf debris that might clog a standard pump intake. Questions? Call (765) 508-4352.

Maintenance is minimal compared to a traditional koi pond:

• Water top-up: Add water periodically as evaporation reduces the reservoir level. The Vault lid allows quick water level checks.
• Pump intake: Rinse the pump intake filter screen seasonally (access via the Vault lid — no digging required).
• Stream surface: Remove debris from stream rocks seasonally.
• Dosing system: The Automatic Dosing System refills automatically — check and refill Prevent for Fountains treatment as needed.
• Lighting: LEDs are long-life; the photocell transformer turns lights on/off at dusk automatically.

No fish to feed. No water chemistry to balance. No annual drain-down required in most climates.

Winterization depends on your climate:

• Mild climates (Zones 7+, rarely below 20°F): Many pond owners run their pondless waterfall year-round. Moving water resists freezing, and the ice formations can be beautiful. Monitor the pump — if the basin freezes solid, remove and store the pump.
• Cold climates (Zones 5–6, like Indiana and the Midwest): When temperatures drop below 20°F consistently, the stream can freeze and cause ice dams that pump water over the liner. Most installers recommend shutting the system down when overnight lows consistently reach 20–25°F, removing the pump and storing it in a frost-free location, and covering the reservoir access point to prevent debris accumulation.
• Spring startup: Reinstall the pump, refill if needed, and restart normally. Consider dosing with an Aquascape bacteria treatment to re-establish biological activity.

The AquaSurge pump should never be stored outdoors while frozen — store it in a bucket of water in a frost-free area to keep the seals from drying out.

Yes — the pondless design is specifically cited as the safest residential water feature format. All water is stored underground in the AquaBlox reservoir; there is no exposed open water surface at grade level. Children and pets can safely walk on the stream rocks. There is no deep basin they could fall into. No fish to harm. The only water at the surface is the shallow stream bed itself, which drains immediately when the pump is turned off.

The 53039 includes: (2) 1-Watt 12V LED Waterfall and Up Lights, a 60-Watt Transformer with Photocell (auto dusk on/off), a 3-Way Quick-Connect Splitter, and a 25' LVL Quick-Connect Extension Cable. Total transformer capacity: 60 watts (LEDs use 2W total, leaving 58W available for additional lighting).

The 3-way splitter provides two open ports for adding additional Aquascape or compatible 12V low-voltage lighting later. Lights are positioned during rock-work installation before surface stones are set. Additional Aquascape LED waterfall and landscape lights are sold separately and connect via the same Quick-Connect system.
