Pentair Small Support Pipe

The Pentair Small Support Pipe (Part #178697Z) is a specialized internal stabilization component designed for Pentair FullFloXF High-Efficiency pool and spa filter systems, including the C-Series cartridge, F-Series fiberglass D.E., and Q-Series Quad D.E. filters. Positioned inside the pressurized filter vessel, this internal PVC guide pipe interfaces with the main internal plumbing manifolds and element support plates to provide essential vertical rigidity. By preventing internal shifting, swaying, or alignment loss when the pool pump initiates a high-flow water cycle, it ensures that the heavy internal filter cartridges or D.E. grids remain securely seated against their sealing gaskets to prevent unfiltered water from bypassing the system.

This support component is manufactured out of durable, thick-walled industrial PVC designed to remain structurally sound under continuous submersion, featuring the following weight profile:

• Actual Product Weight: Approximately 1.0 pound.

• Packaged Shipping Weight: Typically scales at 1.0 to 1.5 pounds depending on the standard protective box dimensions (approximately 6" x 6" x 6") used during transit.
