Product details
The Unicel UHD-SR135 is a 135 square foot replacement cartridge element measuring 8-11/16" across the outside diameter and 34-1/2" long. It is listed as the replacement for the Sta-Rite WC108-53S1X element.
Check the two numbers
Cartridges are chosen by size, not by filter model alone. Pull the old element, measure the outside diameter and the overall length, and match them to the 8-11/16" and 34-1/2" figures here. Getting either wrong leaves the element loose in the tank, and water finds its way past instead of through the media.
Cleaning and replacing
An element like this is rinsed and put back in service several times before it is finished. The signal that it is done is filter pressure that climbs back to where it was within days of a cleaning, or pleats that have gone brittle, matted or torn. At that point no amount of cleaning restores the flow.
What you are buying
This is supplied under the Unicel name and carries the Unicel number UHD-SR135. It is a replacement element for a Sta-Rite filter rather than a Sta-Rite branded cartridge.
