Large Pump Vault for Pondless and Water Feature Installations The EasyPro JAFV Large Pump Vault is a submersible pump housing designed for pondless waterfalls, Just-A-Falls systems, and other water features where the pump must be hidden below grade. The vault holds pumps rated up to 18,000 GPH (68,130 LPH) and provides easy access for maintenance without draining the reservoir. Clean Installation, Simple Pump Access The open-bottom vault sits directly in the gravel reservoir, drawing water through the surrounding media while keeping the pump protected from debris. A removable lid allows fast pump removal for cleaning or replacement without digging out the entire reservoir. Vaults can be paired with extension tubes to accommodate deeper installations or higher gravel levels above the pump. Specification Value Max Flow Capacity 18,000 GPH (68,130 LPH) Dimensions 24" x 24" x 32" tall Installation Type In-ground reservoir / pondless waterfall Compatible Extensions JAFME (12") or JAFVE (18") extension tubes How to Install Place the vault on the base of the reservoir before filling with gravel. Route the pump discharge hose up through or alongside the vault to the waterfall header or spillway. Fill the reservoir with clean gravel around the outside of the vault. Set the pump inside, connect the outlet hose, replace the lid, and fill to operating level. To service: lift the lid, disconnect the pump, and lift straight out. Ideal for pondless waterfalls, Just-A-Falls installations, and commercial water features where a hidden pump location and easy maintenance access are required.
