Generally speaking, for household use the most appropriate filter is the 3/4” .or 1” Spin-Down or Sediment Trapper filter. Irrigation and other higher flow rate applications (>25 GPM) are best served by our 1.5” or 2” Spin-Down or Sediment Trapper models.
A good rule of thumb is to always select the coarsest mesh that will remove the type of sediment you are dealing with. Lower mesh numbers correspond to coarser mesh, and conversely, higher mesh numbers correspond to finer meshes. Please see this sediment chart to determine the recommended mesh size for your application.
Our cold water filters are rated to perform optimally up to 75° F and our hot water filters withstand up to 200° F.
Please see the pressure loss chart in this product brochure for more information.
The following is a list of tested chemicals. Please note that the Hot water Filters and Chemical Resistant filters have different chemical resistance properties than the standard Spin-Down and Sediment Trapper filter models.

In the vast majority of situations, with a properly selected filter size and mesh size, the need to constantly flush will not present itself. In certain applications with extremely fine silt, or abnormally high levels of sediment, the following solutions can alleviate this issue:
Select the proper micron/mesh size
Install an automatic flush valve
Use a step-down system, consisting of a number of filters installed in series, with mesh sizes increasing in fineness.
Filters that are installed in direct sunlight can be fitted with a Rusco Sun Shield, to block the solar rays that encourage algae growth.
Rusco products are stocked by a number of national and regional hardware, plumbing, and specialty stores, as well as a number of online retailers. Please contact us and we will assist you in finding a distributor near you.
The complex answer is that this depends on the amount of sediment your system needs to be removed. The Sediment Trapper models provide extra internal volume for trapping very large amounts of sediment. Generally speaking, we recommend using the Sediment Trapper as a starting point for the smaller 1” and 3/4” sizes, and the Spin-Down model for the larger 1.5” and 2” sizes.
