Bobby_M Sight Gauge

I've hot PBW'd mine on a regular basis also. No problems yet, but I did notice a hairline crack forming at the base of one already after about 10 brews. Guess I should get a spare soon....

Yep. Mine leaked for one or two brews. I noticed the crack. Then the last brew it leaked a lot. I snapped it off and put a 1/2" brass plug in there (during the brew!).

So yeah, I'd say you're on borrowed time.

I had similar issues with Oxy-clean and crazing of polycarbonate. I did some experiments and found that if I filtered my water through a charcoal filter my Oxy-clean solution didn't harm the sight glass.

I've also seen my polycarbonate crack from strong lye solutions (unfiltered water).

I was wondering where to get the number. Thanks

What number are you looking for?

Heh I think he means the (sticker) numbers for the side of the sight gauge.

Seems you were right. Mine gave way today...

Depending on Bobby's quick shipping time to have it for a brew this coming weekend.
Guess I'd better keep a 1/2" plug handy also!
