Cone and basket startup strainers without wire mesh liners are designed for installation with the cone pointing upstream or downstream depending upon which direction there is sufficient room for the length of the cone or basket.
If there are no length issues, flow direction is up to the customer’s preference.
If the strainer points upstream, debris will tend to collect at the strainer’s paddle ring and it will be necessary to clean out any loose debris from the pipe.
If pointed downstream, the debris will collect inside of, and at the end of the strainer; thus easier to clean. If the strainer has a wire mesh liner with a support of perforated material or a heavier wire mesh, the direction of the strainer installation has been predetermined.
