My cooler lining warped, but DID NOT crack, on my first batch. It has a raised 1" lump from the bottom to the top, about 1.5" wide. I've done about a dozen batches with it since, and it works fine. It may be giving me cancer, but it makes some good beer, so it's a bit of a trade off.

I have a friend who has had some warping of the inner liner on the rubbermaid cooler. I'm not sure why or how it happened. Maybe higher temp. mash out? But I do know that it can happen. I haven't had a problem with my own cooler conversion yet.

My ball valve wiggles pretty substantially when I close the valve, would the inclusion of washers stop this problem? Has anyone else had this problem and solved it?

I coiled a SS wire onto a round rod and then pulled the coils out lengthwise to form an open and elongated coil spring. I then inserted this into the SS braid. Works perfectly supporting the braid and is uneffected by heat.

By the way, my 5 gallon Rubbermaid cooler has seen 6-7 batches without any sign of warping.

Mine warped on the first batch right after I poured the strike water in (~170 F). There were creaks and cracking sounds coming from the cooler, so I assume the inner liner was expanding and just started popping out with no where else to go. Now its a permanent feature of the cooler. But like i said, no problems whatsoever. If it lasts a few years, I'd say that's pretty good for a $40 investment. I can just pop out the valve and braid and start with a new cooler when the time comes.

Yes, you may need more outside ss washers than the OP needed in the original build. The ball valve should be tight against the cooler wall.

Thanks. Do you know if the plastic washer the rubermaid cooler comes with is high temperature? I'm thinking of replacing it with a 1/2" silicone gasket but its OD is barely larger than the hole in the cooler. This results in the gasket getting pulled through once the locknut is tightened.

I was going to put on washers anyways, as my SS ball valve handle can't be closed completely (that awkward square cut out near the spigot blocks it from closing all the way). It seems like once the handle hits, the ball valve is completely closed, but I'd like to be safe and space the ball valve out far enough for the handle to lie horizontally, for precaution and aesthetics.

+1
I used round coolers before I went to keggles and experianced the same thing. both were deformed on the inside after starting to use them but they both lasted years and would still be in use if I didn't build a stand and upgrade my equipment.
