I just found a large number of large cracks after removing the tank to perform a descaling. I feel your pain but any addition of insulation should be done by Anova, not their customers. I just submitted a support request, let’s see how that goes
Any chance that improper cleaning solutions are causing (caustic) stress corrosion cracking? In my career we were prohibited Simple Green for causing caustic stress corrosion cracking of many of the transparent plastics but primarily for the blown fuse indicators on control panels.
Another thought is thermal internal stresses that might be visible with a properly applied polarizing lens and light source - like auto rear windows.
Anybody knows the material? I recall PMMA cracks/breaks are very easy to repair with acetone. But I believe the tank will be PC, ABS or some blends of that.
Poly(methyl methacrylate) ( PMMA ). PMMA is also known as acrylic , acrylic glass , brands Crylux , Plexiglas , Acrylite , Astariglas , Lucite , Perclax , and Perspex. PC Polycarbonate. Acrylonitrile butadiene styrene ( ABS )
Actually, I believe it’s made of Tritan but can’t find where I read it.
Tritan is an Eastman Kodak product branded Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, PETP or PET-P )
