Blue Thumb Elite Series | Pond-Less Waterfall Components

Large Elite Pump Canyon

Protect your high-capacity waterfall pump while keeping it accessible for service. Our Large Elite Pump Canyon is a heavy-duty, one-piece molded pump vault designed for the underground reservoir of a large pond-less waterfall or cascading stream.

Its reinforced octagonal design resists pressure from surrounding rockwork, while slotted walls let water enter the pump chamber. The removable lid provides convenient access for maintenance without dismantling the entire reservoir.

Built for High-Flow Pond-Less Waterfalls

Protected Pump Chamber

The rigid molded structure helps protect your submerged pump beneath a rock-covered waterfall basin. Vertical openings allow water from the surrounding reservoir to enter the chamber for recirculation.

Accessible for Maintenance

The detachable top lid gives you access to inspect, clean, or remove the pump. You can keep the working components below the finished rock surface while planning a removable access point.

Is the Large Pump Canyon Right for Your Project?

The Large model is designed for substantial pond-less waterfall installations that need a high-capacity pump chamber and a larger underground reservoir. Its published maximum pump flow is 20,000 GPH.

The Pump Canyon houses the pump, while appropriately sized Basin Matrix boxes and a waterproof liner create additional underground water storage. Water returns through the decorative rockwork, enters the reservoir, and is pumped back to the waterfall spillway.

Before You Order

Confirm your pump's physical dimensions, discharge-plumbing clearance, flow requirements, and the overall reservoir design. The 20,000 GPH rating is the canyon's maximum specified pump flow, not a guarantee of actual waterfall output.

Important: The 57-gallon canyon capacity does not represent the total water volume required for your completed waterfall. The surrounding reservoir must be sized for operating water demand and shutdown drainage.

Considering a Smaller Model?

For lower-flow installations, compare our Small Elite Pump Canyon and Mini Elite Pump Canyon. A lower pump flow requirement alone does not guarantee the smaller vault will accommodate your specific pump and plumbing.

Installation Planning and Setup

The Large Pump Canyon is installed within a waterproof underground reservoir at the lower end of your pond-less waterfall or stream. Plan pump access, water-storage capacity, and plumbing routes before excavation.

1

Plan the Basin

Determine the waterfall route, pump location, and Basin Matrix layout. Our standard installation guide specifies a 34-inch excavation depth for the Large Pump Canyon. Locate buried utilities before digging.

2

Prepare the Lined Reservoir

Remove sharp roots and stones from the excavated area. Install protective underlayment followed by rubber liner. Position the Pump Canyon and surrounding Basin Matrix boxes according to the installation guide.

3

Install Pump and Plumbing

Place a properly sized submersible pump inside the canyon. Connect the pump discharge and plumbing to the upper waterfall spillway. Orient the hose opening toward the plumbing route and retain access to the lid and power cord.

4

Finish, Fill, and Test

Complete the reservoir and stream rockwork, fill the system, and test circulation. Check water levels, connections, and the return path before completing the landscape. Mark the access-lid location with a removable identifier rock for future service.

Compatible Components and Optional Upgrades

Expand Underground Water Storage

Use appropriately sized Basin Matrix water-storage boxes around the Pump Canyon. Their open internal storage spaces increase the available reservoir volume while supporting the planned rockwork above.

Increase Reservoir Depth

Our Large Pump Canyon Extension (PB1977) is designed specifically for the Large Elite Pump Canyon. It can support deeper reservoir configurations when additional underground water storage is needed. Sold separately.

Add Automatic Water Fill

The molded spinweld accommodates our optional Hudson Automatic Water Fill Kit (PB1342). The kit connects to a compatible 1/2-inch water supply and helps replenish water lost through evaporation and splash.

Water pressure: The fill kit is rated for a maximum of 30 PSI. We recommend reviewing the applicable pressure-regulator requirements before connecting it.

Planning the Complete System

Browse our Pump Canyon and Reservoir collection for related storage and waterfall-system components. Select the pump, plumbing, and spillway based on the project's actual operating requirements.

Routine Maintenance and Winter Care

  • Monitor water levels: Keep sufficient water in the reservoir for continuous pump operation. Low water levels can damage the pump.
  • Keep the chamber clear: Periodically remove the access lid and inspect the pump intake and lower chamber for collected debris or gravel.
  • Inspect plumbing: Check the pump discharge, connections, and waterfall return path for leaks or restricted flow.
  • Prepare for winter: If shutting down the waterfall, follow the pump manufacturer's storage requirements. Our maintenance guide recommends cleaning and storing the pump submerged in water in a frost-free location and leaving the underground reservoir at least half full to help prevent freeze-thaw heaving.

For full maintenance and seasonal procedures, use the official pond-less waterfall guide below.

Frequently Asked Questions

Does the Large Elite Pump Canyon include a pump?

No. This listing includes the molded Pump Canyon vault and its access lid. The submersible pump, discharge plumbing, water-storage matrix, liner, and waterfall spillway are purchased separately.

Can I use a pump rated above 20,000 GPH?

The maximum pump flow for the Large Elite Pump Canyon is 20,000 GPH. We do not recommend exceeding that rating. Also confirm the pump's actual physical size and the room needed for discharge plumbing before purchasing.

Does the 57-gallon capacity represent the entire waterfall reservoir?

No. The 57-gallon specification applies to the Pump Canyon itself. A complete pond-less waterfall requires enough underground water storage for operating circulation, evaporation, and water draining back into the basin when the pump shuts off. Basin Matrix boxes can provide additional storage.

How deep should I excavate for the Large Pump Canyon?

Our standard installation guide specifies a 34-inch excavation depth for the Large Elite Pump Canyon. The full excavation dimensions depend on the layout and number of Basin Matrix boxes. Installations using the optional Large Pump Canyon Extension require additional planning.

Can I add an automatic water-fill kit?

Yes. The Large Pump Canyon includes a molded connection for our Hudson Automatic Water Fill Kit, item PB1342, sold separately. The kit uses a 1/2-inch supply connection and has a 30 PSI maximum water-pressure rating. Review the installation requirements and pressure-regulator recommendation before connecting it.

Can I use a Large Pump Canyon Extension?

Yes. Our Large Pump Canyon Extension, PB1977, is designed specifically for this model. It allows deeper reservoir configurations and additional water-storage planning. The extension is sold separately, and the complete excavation and access arrangement should be planned before installation.

What maintenance does the Pump Canyon need?

Keep the pump-access lid accessible and periodically inspect the chamber for debris, gravel, or anything restricting the pump intake. Monitor the operating water level and follow the pump manufacturer's cleaning and seasonal storage instructions. Our pond-less maintenance guide provides additional winterization procedures.
