Atlantic Pump Vault 3900 GPH PV1700

Versatile Underground Pump Protection

Atlantic's PV1700 Pump Vault houses and protects the pumps and plumbing of underground water storage and circulation systems, providing secure, accessible pump housing for pondless waterfalls, wetland filtration, rainwater cisterns, and underground reservoir applications. Rotomolded from virtually indestructible polyethylene, this vault delivers long, worry-free service while accommodating multiple pumps and accessories in a compact, efficient design.

Eco-Blox Integration

Atlantic's redesigned pump vaults occupy the same footprint as Eco-Blox, allowing for simplified installation within rectangular basins. This standardized footprint eliminates guesswork during layout and ensures efficient use of basin space, creating a cohesive underground water storage system with dedicated pump protection.

Multi-Pump and Accessory Capability

Sized to accommodate multiple pumps, the PV1700 also houses ionizers, check valves, and auto-fill valves—consolidating your system's critical components in one protected, accessible location. The tight-fitting cover and generous opening provide easy, secure access to pumps, plumbing, and accessories for routine maintenance and seasonal service.

Applications

Ideal for pondless waterfall systems, underground water storage reservoirs, wetland filtration (upflow and downflow bogs), rainwater cisterns, irrigation systems, and any application requiring secure underground pump housing. Perfect for projects ranging from residential water features to large commercial waterfalls and rainwater harvesting systems.

Smart Design Details

The slotted side design provides critical installation flexibility—either side handles double the rated flow, meaning one side can be completely blocked by liner without affecting capacity. The flat panels feature multiple cut lines that accommodate plumbing from 1.5" through 6", along with auto-fills, overflows, and custom configurations. This adaptability ensures the PV1700 works for virtually any project, from simple pondless waterfalls to complex multi-feature systems.

Frequently Asked Questions

Q: What size pump can the PV1700 accommodate?
A: The PV1700 is rated for pumps up to 3,900 GPH and can house multiple pumps simultaneously for redundancy or multi-feature systems.

Q: Can I use multiple pumps in one vault?
A: Yes, the PV1700 accommodates two or more pumps, allowing for redundancy, seasonal flow adjustments, or powering multiple water features from a single vault.

Q: What accessories can I house in the vault?
A: The PV1700 can house ionizers, check valves, auto-fill valves, and other system components, consolidating your equipment in one protected, accessible location.

Q: What does "either slotted side handles double the rated flow" mean?
A: Each slotted side of the vault can handle the full 3,900 GPH flow independently. If one side is blocked by liner during installation, the vault still maintains full capacity through the other side.

Q: Can I increase the height of the vault for deeper basins?
A: Yes, Atlantic offers pump vault extensions that add the height of one Eco-Blox unit per extension. You can stack multiple extensions to achieve the depth required for your basin.

Q: What size plumbing can I run through the vault?
A: The flat panels feature multiple cut lines that accommodate plumbing from 1.5" through 6", along with auto-fills, overflows, and custom plumbing configurations.

Q: How do I access the pump for maintenance?
A: The tight-fitting cover removes easily without gravel falling into the vault. The generous opening provides easy access to pumps, valves, and plumbing for routine maintenance.

Q: Is the vault strong enough to support gravel and foot traffic?
A: Yes, the low-profile lid is extremely strong and designed to support gravel cover and occasional foot traffic without damage.

Q: Can I use the PV1700 for rainwater harvesting or cistern applications?
A: Yes, the PV1700 works for any underground water storage application, including rainwater cisterns, irrigation systems, and water harvesting projects.

Q: What is the difference between the PV1700 and larger pump vault models?
A: The PV1700 is rated for pumps up to 3,900 GPH and is ideal for smaller to medium applications. Larger models like the PV7500 and PV15000 accommodate higher flow rates and larger pumps for bigger installations.
