Product overview
Sight Glass for 18-Inch and 20-Inch Filters, Replacement for Pentair — an aftermarket backwash part dimensioned to drop into Pentair valve assemblies without modification. In service it handles the discharge of dirty water during the backwash cycle. It is a wear item: the sealing components wear and the sight glass clouds, making it hard to judge when backwashing is complete.
