Frequently Asked Questions

How does the quarter-turn self-cleaning work?

Turning the filter body a quarter turn changes the internal flow direction, opens the bottom flush port, and initiates a reverse backwash that pushes debris out through the flush port - all while the system stays pressurized and running.

Do I need to replace filter cartridges?

No - the stainless steel filter element is permanent and does not require replacement cartridges. Periodic flushing via the quarter-turn mechanism keeps it clean.

What filtration level does this filter provide?

The 140 mesh (105 micron) stainless steel element captures particles that are fine enough to clog drip emitters, injection system valves, and distribution lines.

Can this filter be installed outdoors?

Yes - the Twist II Clean Filter features a rugged design suitable for both indoor and outdoor installation in irrigation and horticultural applications.
