Know before you buy
A pondless system circulates water from an underground reservoir—in this case, the 31-gallon vault—up to a waterfall or fountain, where it then filters back down through gravel and rocks. This eliminates the need for an open pond, significantly reducing maintenance and safety concerns.
Yes, the vault is engineered with a sturdy, high-density polyethylene lid specifically designed to be covered with natural elements like rocks and gravel. It is built to withstand the weight of typical landscape materials used to conceal the unit.
The vault features a pre-cut 3-inch outlet port for your main plumbing connection and multiple inlets to ensure efficient water return. This setup is designed to simplify the installation process for standard pondless waterfall kits.
The capacity primarily determines the volume of water available for the system to run without the pump running dry. While it is perfect for smaller to mid-sized disappearing features, you should ensure your pump flow rate is compatible with the reservoir volume to prevent splashing or water loss.
It is designed for straightforward below-grade installation, making it a popular choice for DIY enthusiasts. You will need to excavate a hole that accommodates the 19.3-inch diameter and 24.5-inch height, ensuring the unit is level for optimal performance.
