Jar Top Automatic Valve Diaphragm | 57473

Dropped this in my 57460 valve and the leak stopped immediately, no more water pooling by the curb. Fit was snug with no trimming needed, and it's been holding steady for about a month now.

The Santaprene material feels way sturdier than the old rubber diaphragm I pulled out, and it seated perfectly in my jar-top valve. Zone 3 is running dry again instead of flooding the yard.

Dropped this in to fix a sprinkler zone that wouldn't shut off, and it sealed perfectly on the first try. The Santaprene material feels thick and durable compared to the torn one I pulled out.
