Sand Filter Glass Bubble

On the top side of my PRO SWIM sand filter (near the gauge) was a little glass jar that screwed into the filter.

That broke this winter. Seems to be glass in the threads. Any ideas on how to get it out?



Hi JJ. The little glass jar is a sight glass. In cases where you can't see the water coming out of your backwash hose you can watch the sight glass, this will tell you when the water is coming out clean and you are done backwashing.

This opening can be plugged off with a bolt or a plug if you do not use the sight glass, not everyone does. If you don't use it there is no need to replace it.

A small screw driver should work to get the rest of the glass out of the threads. Maybe even a few taps with a hammer to get it to start breaking apart. Once the glass starts breaking it should be fairly easy to work out of the threads.
