Atlantic Pump Vault Extension for PV7500/PV15000
Expand Your Pump Vault Capacity for Deeper Basins
Atlantic's Pump Vault Extension increases the height of your PV7500 or PV15000 pump vault, allowing you to accommodate deeper, larger underground water storage basins. Each extension adds the height of one Eco-Blox unit, providing the vertical capacity needed for installations that require additional depth while maintaining the same proven vault design and durability.
Seamless Integration with Atlantic Pump Vaults
Designed specifically for Atlantic's PV7500 and PV15000 pump vaults, this extension maintains the same footprint and construction quality as the base vault. The rotomolded polyethylene construction delivers the same virtually indestructible durability, ensuring long, worry-free service even in demanding underground environments.
The extension integrates seamlessly with the vault's slotted design, allowing water flow from either side while maintaining the double-rated flow capacity. This means one side can be blocked by liner without affecting performance—critical flexibility for real-world installations.

Applications
Ideal for pondless waterfall systems, underground water storage reservoirs, wetland filtration systems, and any installation requiring additional pump vault depth. Perfect for larger basins where standard vault height is insufficient, or when accommodating multiple pumps and complex plumbing configurations in deeper installations.
System Integration
The extension works within Atlantic's modular pump vault system, which occupies the same footprint as Eco-Blox for simplified installation. The low-profile vault lids fit all sizes, support gravel and foot traffic, and can be removed without gravel falling into the vault. This extension maintains all these benefits while adding the vertical capacity needed for deeper applications.
