Heavy Duty Top Manifold With Air Bleed Assembly For Pentair Fns Plus De Pool And Spa Filter Replacement Black Built Tough To Handle Daily Grind Without Any Sweat

Durable air bleed manifold for pool spa filter units
✔️ Fits Pentair FNS Plus DE filters and top manifold replacements

This heavy duty split manifold mounts on top of your round diatomaceous earth filter tank. It channels water straight toward the internal grid while letting air out through the side vent tube. You get steady pressure and clear pool water without constantly bleeding by hand.

✅ Thick PVC shell resists salt corrosion and UV cracking
✅ Inner air bleed valve drops trapped pressure instantly
✅ Reinforced ribs keep the seat aligned under heavy flow
✅ Direct swap fit for Pentair FNS series and major brands

💡 What causes low water pressure in a diatomaceous earth skimmer setup?
- Air pockets and clogged grids choke your flow fast when you are running high demand.
- A handy air bleed manifold vents trapped gas before it locks the suction line.
- Thick PVC seals stay tight against chemical stress and salty weather.
- Smooth circulation kicks back in once you snap the new piece into place.
