Pro-Series Large Vault Extension

Pro-Series pump vault extension is designed to add needed height when a standard Pro-Series vault body does not reach the required basin depth. It stacks directly onto an existing compatible vault and locks in place to help create a secure, stable fit during installation.

Why choose this extension

When water feature basins are deeper than expected—or when the pump intake needs to sit lower for consistent operation—an extension can be a practical way to maintain proper intake placement without reworking the basin. This Pro-Series pump vault extension is intended to increase intake reach while keeping the vault system organized, accessible, and service-friendly.

• Made to integrate with Pro-Series vault systems for a straightforward fit with compatible components
• Helps extend intake depth in deep basins or installations with demanding intake placement
• Supports more consistent pump operation by helping reduce the chance of drawing air during low-water conditions (application-dependent)

Typical use cases

Installers often consider an extension when basin depth exceeds the standard vault reach, in ponds with notable water level fluctuation, or when the pump needs to be positioned deeper to help avoid pulling in surface debris. By adjusting intake depth, you can often improve reliability and reduce nuisance maintenance in the intake area.

Installation notes

This Pro-Series pump vault extension connects directly to the existing vault intake and is designed for quick, tool-free attachment for easier adjustment during setup. As with any vault/intake configuration, confirm component compatibility and verify that intake placement supports your specific pump, basin size, and site conditions.

FAQ

Will this affect pump performance? Properly installed extensions are typically used to improve intake placement; actual performance depends on the full system layout and pump specs.

When is an extension necessary? When the vault body does not reach the depth needed for stable, debris-conscious intake positioning.

How do I confirm fit? Match your vault system to Pro-Series compatibility and confirm the existing intake connection type before installation.
