Hi - has anyone installed an in-line sight glass? I have a new filter and there is no sight glass on the valve.
I'm looking at the Hayward options (like Hayward 2 in. Socket Pool In-Line Sight Glass SP1074S - The Home Depot) , but it's not clear to me if the ID of the sight glass is the OD of the pipe, or if some other kind of connector is needed?
Thanks!
