Screen filters are the most common filters used in the irrigation industry and in most cases the least expensive. They are generally used as a backup for any type of drip irrigation installation and are mainly installed where the quality of water is good. Screen filters are excellent for removing hard particulates from water, such as sand and other small elements often found in city water. The screen filters are not suitable for removing organic materials such as algae, mold and slime. These non-solid materials tend to embed themselves into the screen material where they are very difficult to remove. In other cases they simply slide through the holes in the screen by temporarily deforming their shape. Screen filters are cleaned by removing the cover and hand cleaning the screen.

Installation for 3/4" and 1" MNPT Screen Filter

Starting the irrigation system from a PVC pipe:

1.       Connect a 3/4” and 1" MNPT filter directly to the outlet of an AC valve or battery operated controller.

2.       Connect a 3/4” and 1"  25 PSI FNPT x MNPT pressure regulator to the filter.

3.       Connect a 3/4" and 1" FNPT swivel adapter to the 3/4” 25 PSI pressure regulator.

4.       To start the drip system, connect the poly drip tubing to the adapter by wiggling and forcing the drip tubing into the compression side of the adapter.

5.        Lay out the drip tubing to the garden area. The 1/2” drip tubing is used as the main line for drip systems into which drip emitters, micro sprinklers or 1/4”  micro tubing are inserted

  • ·  Make sure that the water flow direction matches for each component, if it is in line with the water flow.
  • ·  Use Teflon Tape only with the filter and make sure to remove all Teflon tape excess.
  • ·  Pressurize the system and make sure that water is not leaking from the unit or any part along the line. Test the assembly manually and automatically via the controller and then program the controller.
