The PB1175's published 57-gallon capacity describes its pump chamber, not the complete waterfall reservoir. Aquascape does not publish a directly comparable chamber capacity. Both products require properly sized underground water storage. The removable lid on PB1175 provides access for inspection but is not a separate inspection port. Autofill equipment is sold separately for both vaults.
Which Pond-Less Pump Vault Is Right for Your Project?
Choose the Aquascape Pondless Waterfall Vault when building with compatible AquaBlox® storage modules, when the smaller published housing footprint better suits the reservoir layout, or when a built-in water-level inspection port is important. The vault also provides a built-in mounting area for optional autofill equipment. Its maximum pump flow rating is 12,500 GPH.
Consider our Blue Thumb Large Elite Pump Canyon PB1175 for a larger, high-flow pond-less waterfall using our Basin Matrix storage system. It supports a higher maximum pump flow of 20,000 GPH, offers a 57-gallon pump chamber, and has a molded fitting for our optional automatic water-fill kit. A removable lid provides access for water-level checks and pump maintenance.
Both are standalone pump chambers, not complete waterfall systems. We recommend confirming the pump's physical dimensions, plumbing, reservoir layout, and required operating flow before choosing either model.

Planning Your Pond-Less Reservoir Installation
The vault is installed in the underground collection reservoir at the lower end of a pond-less waterfall. Water flows through the waterfall, returns into the hidden reservoir, enters the pump chamber, and is pumped back to the upper spillway.
1
Plan the Reservoir Layout
Determine the pump location, AquaBlox® module arrangement, plumbing route, and required excavation area. Account for sufficient operating water volume and the water draining back into the basin when the pump shuts off.
2
Prepare the Excavation and Liner
Excavate the vault location at the lowest point of the reservoir. Prepare a smooth, compacted base and install the specified geotextile underlayment and EPDM liner according to the Aquascape installation manual.
3
Position the Vault and AquaBlox®
Place the vault alongside the selected storage modules in the manufacturer's recommended arrangement. Check the module orientation, support, backfill clearances, and optional extension requirements before completing the reservoir.
4
Install Pump and Plumbing
Position a compatible submersible pump inside the vault. Route the plumbing through the provided side opening and connect it to the upper waterfall. Complete the reservoir, fill with water, test operation, and maintain access to the inspection cap.
Important Installation and Compatibility Notes
Large-pump plumbing: The vault includes a factory-provided 3-inch side opening. Aquascape specifies that larger pumps using 3-inch plumbing require the optional Vault Extension 49001 and AquaBlox® Large Water Storage Modules.
Autofill compatibility: The Aquascape vault provides a built-in mounting area for an optional automatic water-fill system. The mounting area does not mean that an autofill valve, water-supply line, or complete autofill kit is included.
Excavation space: Aquascape recommends additional clearance around the basin for proper backfilling and compaction. Actual excavation dimensions depend on your storage-module arrangement.
Groundwater: Aquascape specifies that the high water table must remain at least 3 feet below the bottom of the AquaBlox® structure.
Refer to the official manual for the complete installation requirements before beginning excavation.
Routine Maintenance and Winter Care
Monitor the water level. Use the removable inspection cap to check the underground reservoir. Maintain enough water for the pump to operate properly, accounting for evaporation and splash loss.
Inspect the pump chamber. Periodically remove the lid to inspect the pump, remove debris, and confirm that the intake openings and plumbing remain unobstructed.
Prepare for freezing temperatures. Follow the pump manufacturer's winter storage requirements. When applicable, slope the flexible plumbing back toward the reservoir to help water drain after pump removal. Properly drain and winterize pumps, tubing, and check valves as required by Aquascape's warranty terms.
Limited lifetime manufacturer warranty. Aquascape covers qualifying manufacturing defects in the Pondless® Waterfall Vault for the lifetime of the product, subject to proper installation, maintenance, proof of purchase, and applicable exclusions. Labor, removal, shipping, and reinstallation expenses are excluded.
Installation Manual and Product Resources
Review the manufacturer documentation before installation. The Aquascape guide covers the vault, optional extension, AquaBlox® placement, excavation, plumbing, maintenance, and warranty requirements.
The manufacturer manual covers Aquascape items 49000 and 49001. Blue Thumb's Large Elite Pump Canyon PB1175 uses a different installation system and requires its own documentation.

Frequently Asked Questions
Does the Aquascape Pondless Waterfall Vault include a pump?
No. The AI49000 listing includes the vault housing, removable lid, and water-level inspection cap. The submersible pump, AquaBlox® storage modules, liner, plumbing, and waterfall components are sold separately.
How does this compare with Blue Thumb's Large Elite Pump Canyon PB1175?
The Aquascape vault supports a maximum pump flow of 12,500 GPH, includes a built-in water-level inspection port, and has a mounting area for optional autofill equipment. Our Large Elite Pump Canyon PB1175 supports up to 20,000 GPH, provides a published 57-gallon pump chamber, and includes a fitting for an optional autofill kit. Its removable lid provides access for water-level checks. The Aquascape vault is designed for AquaBlox® storage modules, while our Large Pump Canyon is designed for compatible Blue Thumb Basin Matrix reservoir layouts.
Is the Blue Thumb Large Elite Pump Canyon better for higher-flow waterfalls?
Our PB1175 has a higher published maximum pump flow rating of 20,000 GPH compared with 12,500 GPH for Aquascape AI49000. This makes it an option worth considering for larger, high-flow waterfall projects. However, actual compatibility depends on pump dimensions, plumbing, reservoir sizing, and system design rather than maximum GPH alone.
Can I install an automatic water-fill system on the Aquascape vault?
The Aquascape Pondless Waterfall Vault has a built-in mounting area intended for optional autofill equipment. The automatic fill valve, water-supply components, and associated plumbing are not included with the standalone vault. Confirm the selected autofill equipment is compatible before installation.
Can I use AquaBlox Large modules with this vault?
Yes. Aquascape supports deeper reservoir configurations using AquaBlox® Large Water Storage Modules and the optional Pondless® Waterfall Vault Extension 49001. The extension is sold separately and must be selected according to the installation requirements.
Can I use a pump with 3-inch plumbing?
The vault has a factory-provided 3-inch side opening. Aquascape specifies that larger pumps using 3-inch plumbing require the optional Vault Extension 49001 and AquaBlox® Large Water Storage Modules. Confirm the pump's physical fit, connections, and complete reservoir configuration before ordering.
Can I check the water level without removing the vault lid?
Yes. The removable inspection cap allows you to check the reservoir water level without lifting the entire lid. This is useful when the vault is concealed beneath decorative stone.
Can I use Blue Thumb Basin Matrix boxes with the Aquascape vault?
The Aquascape vault is designed to integrate with AquaBlox® storage modules. Compatibility with third-party reservoir boxes is not established by the manufacturer documentation. We recommend verifying the full design before combining components from different systems. For a Blue Thumb Basin Matrix installation, consider our Large Elite Pump Canyon PB1175.
