Unicel DE Filter Grid Nozzle – For DE & Cartridge Filters
Maintain Peak Filtration Performance with the Unicel DE Filter Grid Nozzle
Pool owners know that keeping water crystal-clear is about more than just adding chemicals — the heart of a healthy pool is its filtration system. Every part of that system plays a role, right down to the smallest nozzle inside your filter. The Unicel DE Filter Grid Nozzle is a precision-made replacement part designed to restore and maintain proper water flow in both DE (Diatomaceous Earth) and cartridge filters.
A worn, cracked, or missing nozzle may seem insignificant, but it can cause uneven flow, unbalanced DE coating, premature grid wear, higher operating pressure, cloudy water, and even strain on your pool pump. By replacing damaged nozzles with genuine Unicel-manufactured parts, you protect the performance of your entire filtration system and extend the life of your grids or cartridges.

Why the Nozzle Plays a Critical Role
Inside your filter manifold, nozzles guide water evenly through each grid or cartridge. If one nozzle is missing or failing, the system’s performance suffers. Here’s why these small parts are so important:
-
Directs Water Flow – Ensures even distribution across all filter surfaces.
-
Prevents Uneven Pressure – Balances workload to reduce strain on grids or cartridges.
-
Protects from Premature Wear – Avoids the stress caused by improper water distribution.
-
Keeps Filtration Consistent – Prevents bypass and maintains clear water quality.
Replacing nozzles regularly is one of the simplest and most cost-effective ways to maintain water clarity and extend equipment life.

The Unicel DE Filter Grid Nozzle is manufactured from UV-resistant, chemical-resistant plastic designed to handle years of exposure to pool chemicals, fluctuating water conditions, and high pump pressures. Precision molding ensures exact dimensions, so the nozzle fits securely into the manifold without leaks or wobbling.
-
Tough Polymer Construction – Withstands chlorine, DE powder, acids, and other chemical treatments.
-
Perfect OEM Fit – Designed to match original dimensions for easy replacement.
-

When Should You Replace Nozzles?
Every time you clean your filter, inspect the nozzles closely. Signs that it’s time for replacement include:
-
Cracks, chips, or visible wear
-
Warped or brittle plastic
-
Loose or unstable fit in the manifold
-
Missing nozzles from the assembly
Even a single broken or missing nozzle can throw off water balance inside the filter, forcing the pump to work harder and reducing overall efficiency.

Yes — it is compatible if your system uses Unicel-style grids. Always verify measurements.
Q3: Can this be used in cartridge filters as well?
Yes. Though often used in DE filters, this nozzle also works in certain cartridge filter manifolds.
Q4: Do I need special tools?
No. The nozzle simply push-fits into the manifold securely.
Q5: Is it resistant to pool chemicals?
Yes. The high-grade polymer resists chlorine, acids, and other chemicals.
Q6: What happens if I ignore a broken nozzle?
Your filter efficiency drops, grids wear faster, pump strain increases, and water quality suffers.
Why Replacing Nozzles Saves Money
Neglecting a worn nozzle can result in:
-
Increased pump run time and energy use
-
Faster wear on expensive grids or cartridges
-
More frequent cleaning cycles
-
Potential manifold or pump damage
