I have a 70 qt. and a 50 qt. cooler. The 70 qt. cooler has the braid from a water heater hose and the 50 qt. has the braid from a water supply line. I had a stuck sparge with the 50 qt. cooler my last two brew sessions. The first time it happened, I thought I had over crushed. This past weekend, I added a couple of handfuls of rice hulls because the grist contained 50% wheat and I still had the problem. After the 70 qt. cooler was drained for the first 10 gallon recipe, I transferred the mash from the 50 qt. to the 70 qt. and it drained just fine.

I'm guessing that the braid is being compressed too much by the weight of the grain in the 50 qt. cooler and over time (4 years of brewing with this tun) the braid won't spring back. Is anybody using something rigid inside of the braid to keep it flowing more freely? I was thinking about wrapping some bare copper wire around a small piece of pipe and placing the coiled copper in the braid. Perhaps drilling a bunch of holes in a copper pipe inserted into the braid might help. I've used a Bazooka screen in the past, but I don't think it filters out the smallest stuff as well as the braid.

Thanks for any direction.

I recommend using 1/6 the weight of the non hulled material in rice hulls. Perhaps a "couple of handfuls" was not enough.

I've used the same braid in mine for over 12 years and 396 batches. No wire inside, no crushing. Why not just replace the bad braid with the good stuff?

Dan, I've never had a problem with this recipe and a couple of handfuls of rice hulls, so I'm pretty sure it is the braid.

Yeah Denny, the simplest thing would be to replace it. I like challenges though. Off to get a new water heater hose.

I, like Denny have used a braided hose for years without an issue. I have a regular water supply line like the one shown in this video

and even though it is a small diameter, still works fine.
