Cash Acme17148-0000 V3 Vacuum Breaker, 1 Count (Pack of 1), Brass

So far so good. Great invention.

Had a plastic vacuum break that cracked and flooded my yard. After that I changed them all to these very sturdy brass breakers. I'd give them 5 stars except the set screw is not made of CRES and corroded pretty bad, almost wouldn't come out and actually ruined the breaker threads somewhat. Another minor issue, the plastic tip in the picture at the center protrudes a good amount and interferes with the "domed" style filter washers ( Gilmour Metal Hose Coupling Filter Washers 02FW ). Not a big deal, really just depends on your application. Good buy, but throw away the set screw.

Does not work as designed.

nice device
