Description
Designed for dual-pump configurations in Gecko Aquaflo systems, the Gecko Aquaflo Val-Pak AC Series Pump Base (91100000) provides a sturdy foundation for two AC Series pumps. This item is a discontinued by manufacturer part, meaning it’s typically sourced through secondary channels, but it remains a practical choice for upgrading or restoring dual-pump setups that rely on consistent, level mounting and aligned plumbing. The unit is sold in pairs, as the setup requires two bases to support the full dual-pump arrangement.
Why this dual-pump base matters
- Stable, level footing for two pumps. Each base is engineered to keep AC Series pumps securely in place, helping to prevent wobble that can lead to leaks or wear on connections.
- Aligned plumbing footprint. The paired bases help maintain consistent spacing and alignment between pumps, making suction and discharge runs cleaner and easier to seal.
- Vibration control and durability. A solid mounting platform reduces movement during operation, contributing to quieter performance and longer service life for connected components.
- Simple integration with existing AC Series equipment. Specifically designed to complement Gecko Aquaflo AC Series pumps, ensuring compatibility with common valve layouts and standard unions used in pool and spa systems.
- Practical for redundancy and multi-pump configurations. Ideal for setups where a second pump provides backup, seasonal demand management, or separate filtration zones within the same pool system.
Who should consider this part
The Gecko Aquaflo Val-Pak AC Series Pump Base is best for pool and spa professionals, installers, and DIY enthusiasts who are outfitting a dual-pump arrangement with AC Series equipment. It’s particularly useful when upgrading an older system that relied on separate, unpaired bases or when rebuilding a dual-pump configuration that requires precise alignment for optimal flow and maintenance access.
Installation considerations and tips
Before you start, confirm that you’re working with AC Series pumps and understand that this part is designed to be used in pairs (two bases). General installation guidance includes:
- Place both bases on a flat, level equipment pad. Ensure there is enough clearance for pump maintenance and for accessing unions and valves.
- Align the bases so the pumps’ footprints are parallel and the discharge/return lines line up with your plumbing layout. Misalignment can complicate sealing and increase stress on fittings.
- Secure each base to the pad with appropriate fasteners suitable for outdoor pool equipment. Ensure the mounting surface can support the combined weight and vibration of both pumps.
- Mount each AC Series pump onto its base using the manufacturer’s mounting holes, then connect suction and discharge plumbing with union fittings to simplify future service.
- After mounting and plumbing are complete, fill and prime the pumps, then check for leaks and confirm that both pumps operate smoothly without binding or excessive vibration.
Important notes
This product is marked as discontinued by the original manufacturer. If you’re rebuilding a system, this base pair can still deliver reliable support when paired correctly with compatible AC Series pumps. Always verify part number 91100000 and ensure you’re purchasing the exact dual-base configuration required for your installation.
Practical considerations for alternatives
If you’re exploring options beyond the discontinued Val-Pak base, look for replacement mounting solutions that match the AC Series footprint and offer similar stability, alignment, and vibration-minimizing benefits. Prioritize units that provide level mounting surfaces, durable outdoor-grade construction, and straightforward compatibility with Gecko Aquaflo components to maintain a clean, serviceable pool system.
With the Gecko Aquaflo Val-Pak AC Series Pump Base (91100000), you’re equipping your dual-pump setup with a purpose-built foundation that fosters reliable operation, easier maintenance, and clean piping alignment—even when sourcing a discontinued part. Suitable for thoughtful upgrades and professional remodeling projects, this base pair helps ensure your AC Series pumps perform as intended in demanding pool environments.
