The 3/4" Y Screen Filter (FYSC34) utilizes innovative "Spin Clean" technology to provide superior, low-maintenance protection for your hard-plumbed drip irrigation or sprinkler system. Featuring standard 3/4" Male Pipe Threads (MPT) on both the inlet and outlet, this robust filter integrates seamlessly into PVC manifolds and connects perfectly with standard irrigation valves. What sets it apart is its unique internal design: incoming water is swirled, actively forcing sediment and debris down into the bottom basin rather than allowing it to cake onto the screen. This semi-self-cleaning action keeps your delicate drip emitters and micro-sprayers free of clogs longer than standard Y-filters.
Designed to handle flow rates up to 9 Gallons Per Minute (GPM) at a maximum of 80 PSI, this filter is equipped with a highly durable 150-mesh stainless steel screen. When the bottom basin eventually fills with captured debris, maintenance is incredibly fast and simple—just turn the convenient ball valve at the bottom to flush the sediment out instantly while the system is pressurized. For a complete and fail-safe head assembly, we highly recommend pairing this screen filter with a compatible 3/4" pipe thread pressure regulator. Please note: To function correctly, this filter must be installed facing downward, and it is not rated for constant pressure.

Build your pipe-threaded drip irrigation 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.
Step 2: Attach to Your Valve (Crucial Orientation)
Thread the inlet of the filter directly into the downstream side (outlet) of your automated irrigation valve. Important: The filter must be installed facing downward, and the directional flow arrow must point away from the incoming water source.
Step 3: Add a Pressure Regulator
Thread a compatible 3/4" pipe-threaded pressure regulator onto the outlet of the filter, followed by your tubing adapter to transition into your poly mainline.
Step 4: Routine Flushing
Periodically open the ball valve at the bottom of the filter while the system is actively running and pressurized to quickly blow out any sediment trapped in the lower basin.
How does the "Spin Clean" feature work?
The filter's internal geometry forces incoming water into a swirling, centrifugal motion. This spinning action throws heavier dirt, sand, and sediment outward and down into the bottom basin, preventing it from sticking to the stainless steel screen.
This semi-self-cleaning action means you have to manually scrub the screen far less frequently than with standard Y-filters.
Can I install this filter horizontally?
No, to take advantage of the Spin Clean action and allow the sediment to properly fall into the flush basin, the filter canister must be installed pointing downward.
Always follow the directional flow arrow stamped on the body to ensure water is moving the correct way through the screen.
Can I leave this filter under constant pressure?
No, this filter is not rated for constant pressure. It has a maximum limit of 80 PSI and must be installed after your automated timer or irrigation valve.
Installing it before the valve leaves it pressurized 24/7, which can eventually cause the canister body to stretch, crack, or leak over time.
How should I prepare my filter for winter?
Before the first freeze, open the bottom ball valve to drain all water from the basin. Then, unscrew the canister, remove the stainless steel screen, and bring both components indoors for the winter.
Leaving water trapped inside the rigid plastic canister during freezing temperatures will cause the housing to crack.
Please note the strict requirements for this component:
