This part was an exact replacement for the venturi assembly for my Kenmore water softener. It was very easy to replace. Didn't even have to turn off the water in the block. My water softener didn't pick up enough brine during the cleaning cycle and the salt tank was full of water for several weeks. The venturi assembly has a pair of very tiny rubber holes inside. Tried to clean the old assembly - to no avail. The line fit was tight, two o-rings were fine, nothing was leaking. I thought the two rubber holes might have deteriorated over the past 10 years of use. Replacing the entire venturi assembly solved the problem. The block works perfectly again.
