The Atlantic Water Gardens PV15000 (Item 89584) is a professional-grade, rotomolded polyethylene pump vault engineered to house and protect submersible pumps and plumbing in pondless waterfall systems, disappearing fountains, and large recirculating water features. Designed to occupy the exact same footprint as Atlantic Eco-Blox, the PV15000 integrates seamlessly into rectangular underground reservoirs — no special basin shaping required.
Measuring 27”L × 16”W × 27”H, the vault accommodates two or more large submersible pumps and handles up to 15,000 GPH total flow. Each slotted side independently handles double the rated flow — meaning even if one side is blocked by a pond liner during installation, the other side maintains full 15,000 GPH capacity. Flat panels accept plumbing up to 3” diameter and auto fill valve assemblies. The low-profile lid opens to 12.25” × 14.75” for tool-free pump access and can be removed without disturbing surrounding gravel.

Installation Overview
- Excavate the basin to accommodate Eco-Blox blocks in a rectangular layout; the PV15000 occupies one standard Eco-Blox footprint position
- Set the vault level in the center of the Eco-Blox reservoir; position it for pump access from above
- Cut flat panel knock-outs to the required plumbing diameter (up to 3”); run discharge plumbing out through flat panels to the waterfall or feature return
- Install pump(s) inside the vault; route power cords through separate cord seal fittings to avoid water intrusion
- Install the low-profile lid; cover with gravel or rock decorative material — lid supports foot traffic and gravel weight without sinking
- For deeper basins, stack PVEXT extension rings underneath the vault base (18-3/8” per extension = one Eco-Blox layer)
- Optional: install Atlantic Auto Fill Kit (item 74246) through a flat panel for automated water level management

Frequently Asked Questions
How many pumps can the PV15000 accommodate?
The PV15000 is designed to accommodate two or more submersible pumps. This versatility allows you to run independent waterfall circuits, a dedicated filtration return, or redundant pump setups for commercial installations — all housed and protected within a single vault. Total supported flow is up to 15,000 GPH combined.
Is the PV15000 compatible with Eco-Blox water matrix blocks?
Yes. The PV15000 is specifically redesigned to occupy the exact same footprint as Atlantic Eco-Blox (item 74234), allowing it to lock seamlessly into a rectangular Eco-Blox basin — no custom excavation or shaping required. The vault slots into the Eco-Blox grid as if it were simply a solid Eco-Blox unit, maintaining the structural integrity and rectangular layout of the reservoir.
Can the vault handle heavy rock and foot traffic?
Yes. The PV15000 is rotomolded from virtually indestructible polyethylene — a process that creates walls with uniform thickness and no weak seams. The extremely strong low-profile vault lid is engineered to support gravel, large decorative stones, and regular foot traffic without collapsing or flexing. The lid is also designed for removal without disturbing surrounding gravel — it lifts cleanly.
What size plumbing can be used with this vault?
The PV15000 features multiple flat panels that can be cut to accommodate plumbing from 2” up to 3” in diameter. The flat panels are also ideal for installing the Atlantic Auto Fill Kit (item 74246) — an automated water level valve that maintains reservoir water level during evaporation without manual refilling. Either slotted side also handles double the rated flow (30,000 GPH per side), so if one side is blocked by pond liner, the other side maintains full 15,000 GPH capacity.
How do I add depth to the vault for larger reservoirs?
For deeper pondless waterfall basins, use the Atlantic PVEXT Pump Vault Extension. Each PVEXT extension measures 27”L × 16”W × 18-3/8”H — exactly the height of one Eco-Blox layer. Stack extensions beneath the vault to increase overall depth. The PVEXT is compatible with both the PV7500 and PV15000 vaults.
Does the PV15000 come with a warranty?
The Atlantic Water Gardens PV15000 is backed by a Lifetime Warranty. The rotomolded polyethylene construction is resistant to corrosion, UV degradation, and chemical breakdown, making it genuinely built for the lifetime of the installation. Contact us at support@pondprodirect.com or (765) 508-4352 for any warranty questions.
