The Pondless® Waterfall Vault's standard height is for basins using the Small AquaBlox®. Optional Pondless® Waterfall Vault Extensions can be used when creating deeper basins using the Large AquaBlox®.
The vault's extra wide opening provides easy access and the large interior fits a wide range of pump sizes. The lid is easy to camouflage, and includes a built-in water level inspection port Allowing it to be buried out of sight.
