Pentair Outlet Assembly

The generic term Pentair Outlet Assembly most frequently references a primary internal plumbing manifold or standpipe unit—such as the Pentair Standpipe Outlet Assembly (Part #190037) for FNS Plus D.E. filters, the Clean & Clear Plus Bottom Outlet Pipe Assembly (Part #170035), or the Sta-Rite System 3 Outlet Assembly (Part #23911-0102). Molded from rigid, heavy-wall PVC or specialized high-density polymers, this vital configuration serves as the central collection corridor at the base of the filter tank. It gathers water that has successfully passed through the filter grids or cartridges and routes it cleanly back out through the return bulkhead to the swimming pool. By providing a secure, leak-proof hydraulic hub within the pressurized tank, it ensures maximum water flow efficiency and structural alignment under constant pump pressure.

Because the designation covers a few different filter lines, the specific unit weight varies by model:

• Pentair 190037 (FNS Plus 60 D.E. Tall Standpipe): Possesses an actual product weight of 2.0 pounds (shipping at roughly 2.5 to 3.0 pounds).

• Pentair 170035 (Clean & Clear Plus Bottom Manifold): Features a stouter layout weighing approximately 2.3 pounds.

• Pentair 23911-0102 (Sta-Rite System 3 Outlet Assembly): Weighs approximately 1.8 to 2.0 pounds.
