Filter FAQ's

The more open screen area you have, the less maintenance you will do. You can always bush down a larger size inlet and outlet to accommodate your pipe size.

32 mesh is the most common for sprinklers. If particles pass through 32 mesh they will continue all the way out the sprinkler heads. For sand use a 50 or 100 mesh. For drip systems use a 150 or 200 mesh.

Always install filter with clean-out end horizontal or tipped downward. Install in a valve box or out of direct sunlight. See our installation page.

You may need to go to a coarser size screen. You can also consider changing to a larger size filter; this will give you more open screen area for longer periods in between maintenance.

At the bottom of our filters there is either a ½", 1" or 1 1/2" thread (depending on the model) to install a manual flush valve. Open this while the system is running and the excess debris will flush through the valve. If there is still a lot of debris plugged in the screen you will have to remove the screen and use running water and a fine bristle brush to remove the debris.

Our filters are rated at 200 PSI max working pressure.

Thermoplastics decrease in strength when the temperature rises above 73° F, maximum operating temperature should not exceed 120° F.

Keep you filter out of sunlight. Filter should be installed underground, kept it in a shaded area or place a cover over the filter.
