Premium Constant-Pressure Protection for Organic Debris
The Arkal Disc Filter is widely recognized as one of the finest, highest-quality irrigation filters on the market today. If your water source comes from a pond, ditch, or lake and struggles with heavy organic matter like algae, this is your ultimate solution. Instead of a traditional mesh screen that easily clogs with slime, this filter utilizes a stack of grooved plastic discs to trap debris across a three-dimensional depth. It is highly recommended to pair this filter with standard automated irrigation valves to safeguard your entire downstream drip system from catastrophic clogging.
Built with a heavy-duty Y-style body, Arkal disc filters are rated for constant pressure up to an incredible 140 PSI. This means you can confidently install them directly onto your mainline upstream of your valves and timers without fear of the canister stretching or bursting. Featuring standard Male Pipe Threads (MPT) on both the inlet and outlet, they integrate perfectly into rigid PVC manifolds. When it is time for maintenance, cleaning is a breeze—simply unscrew the canister, remove the disc spine, loosen the discs, and spray them clean with a hose.
- Superior for Algae: The stacked disc design creates a 3D depth filter that traps organic slime and algae far more effectively than flat screen filters.
- Constant Pressure Rated: Safe to install completely upstream of your automated valves and timers. Handles continuous mainline pressure up to 140 PSI.
- Standard Pipe Threads: Features Male Pipe Threads (MPT) for secure, leak-free integration into standard PVC plumbing and manifolds.
- Highly Durable Element: The stacked grooved discs are virtually indestructible, meaning you rarely (if ever) need to replace them, unlike easily torn screens.
- Easy to Clean: When the spine is removed from the housing, the discs easily loosen, allowing you to quickly spray out trapped dirt with a standard garden hose.

Build your pipe-threaded head assembly safely.
Step 1: Prep the Threads
Because this filter utilizes Pipe Threads (MPT), you must apply 2 to 3 wraps of Teflon tape to both the inlet and outlet threads to ensure a watertight seal. Do not use liquid pipe dope or over-tighten.
Step 2: Install the Filter
Thread the Arkal filter into your PVC manifold. Because it is rated for constant pressure, you have the flexibility to install it either upstream (before) or downstream (after) of your automated valves. Ensure the directional flow arrow points downstream toward your emitters.
Step 3: Adapt to Hose (If Needed)
If you are attaching this filter directly to a garden spigot or hose-end timer, thread a hose-to-pipe thread adapter onto the inlet and outlet.
Step 4: Routine Cleaning
Periodically turn off the water, unscrew the main filter canister, and remove the internal disc spine. Loosen the tension nut at the top of the spine so the discs separate slightly, then rinse them thoroughly with clean water before reassembling.
