Compatibility & Fitment

Compatible with Pentair Clean & Clear Plus, Quad DE, and FNS Plus filtration systems, including the following models:

  • Clean & Clear Plus: CCP240, CCP320, CCP420, CCP520
  • Quad DE: Quad 60, Quad 80, Quad 100
  • FNS Plus: FNSP24, FNSP36, FNSP48, FNSP60

When to Replace

Replace the drain plug cap assembly when you notice water leaking from the drain port, a cracked or visibly worn plug, a damaged O-ring, a loose fitting, or continuing water loss after tightening the existing plug. A compromised seal can affect maintenance drainage and filtration system operation.

Installation Tips

  1. Turn off the pool filtration system power.
  2. Open the air relief valve at the top of the filter to release pressure.
  3. Remove the old 190030 drain plug by turning it counterclockwise.
  4. Align the replacement plug and tighten it clockwise by hand or with a 7/8-inch wrench.
  5. Restore system operation and inspect the connection for leaks.

No special tools are required for installation. The product includes lifetime protection against defects or issues.

FAQ

This drain plug cap assembly is compatible with Pentair Clean & Clear Plus, FNS Plus, and Quad DE pool and spa filters. It fits the filter tank drain port and includes the matching O-ring for sealing.
It replaces Pentair part number 190030 and is also identified by item model number 698183.
Common signs include water dripping from the filter drain port, an O-ring that is flattened, cracked, brittle, or swollen, visible damage to the cap threads, or a cap that will not tighten securely. A leak can also occur if the O-ring is missing or improperly seated.
Turn off the pump, relieve all filter pressure, and close the appropriate valves before removing the old cap. Clean the drain port and sealing surface, lightly lubricate the new O-ring with pool-equipment-safe silicone lubricant, seat it correctly, and hand-tighten the cap. Restore the valves and check carefully for leaks while the system is running.
Confirm that the filter is a Clean & Clear Plus, FNS Plus, or Quad DE model and compare the old cap and drain-port threads with the replacement. Inspect the drain-port housing for cracks or damaged threads, since replacing the cap will not correct damage to the filter body. Always relieve pressure before removing any filter fitting.
