Product overview
Sight Glass, 2-Inch, Clear, Replacement for Pentair Valves — 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. Replacement is routine: the sealing components wear and the sight glass clouds, making it hard to judge when backwashing is complete.
