Plastic Mash Tun Issue
« on: February 08, 2015, 12:30:00 pm »
I have a 10 gallon Rubbermaid round cooler for a mash tun. Today was my second time using it and I noticed something odd today. About 30 minutes or so after sparging I started to clean the spent grain out and proceed to rinse out w cold water.

I noticed a crinkling sound coming from inside the walls of the cooler. I'm wondering if something is separating in there, perhaps the inner and outer wall? Just throwing it out there in case someone else has noticed this. Hopefully this isn't the first sign of warping.

I have he same and experience the same thing. Its the inner plastic lining expanding and contracting from hot/cold.

That's my guess. Heat makes things grow, cold makes them shrink. Just roll with it

The old Rubbermaid/Gott beverage coolers were built for heavy use at construction sites and in industrial settings.  The new Rubbermaid beverage coolers are not built to the same standard.  The yellow industrial Igloo coolers are built to the old standard.
