Amiad Filters (High Pressure)

Build your high-pressure 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 Amiad 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.

Step 3: Adapt to Hose (If Needed)
If you are attaching this filter directly to a garden spigot or timer, thread a hose-to-pipe adapter onto the inlet and outlet.

Step 4: Routine Flushing
Periodically open the flush valve at the bottom of the filter while the system is actively running and pressurized to quickly blow out trapped sediment without unscrewing the canister.

Can I leave this filter under constant pressure?
Yes! Unlike many standard irrigation filters, the Amiad High-Pressure series is built and heavily reinforced to withstand constant pressure up to 140 PSI.

This means you can safely install it directly onto your mainline before your automated timer or irrigation valves, protecting the entire valve manifold from debris.

How do I attach this to my garden hose?
These filters feature standard Male Pipe Threads (MPT) and will not thread directly onto a garden hose or outdoor spigot.

If you are connecting this filter to a hose-threaded system, you will need to purchase and apply standard hose-to-pipe thread adapters to bridge the connection.

What is the difference between the 1 1/2" and the 1 1/2" Super model?
Both handle the exact same flow rate (66 GPM) and use the same pipe threads, but the "Super" model features an extended canister body that houses a significantly larger screen.

This double-sized screen gives you twice the filtering area (52 sq. in. vs 26 sq. in.), which means it can hold significantly more debris and drastically reduces the frequency of manual cleanings.

How should I prepare my Amiad filter for spring watering?
As you set up your system for spring, ensure the water is turned off, unscrew the main canister, and inspect the stainless steel screen for any winter scale or damage.

Clean it thoroughly, or install a fresh replacement screen if necessary. Ensure the O-ring is properly seated and lubricated before hand-tightening the canister back on, then run the system to verify there are no leaks.
