Review on Enhance Your Plumbing System with Homewerks VAC VBK X1B Traditional Anti Siphon Replacement by Ryan Gilliam

Neither my existing faucet nor the anti-siphon block had a name or part number (the faucet only has "US" on one side and "ABP" imprinted Another). others), so I could only measure it. Original part in size 7/8 OD with a pattern that looks like a thin thread. I couldn't find it anywhere (many stores are now closed) so I jumped at the chance to buy this device. And it fits perfectly. You don't have to overtighten it, just press it firmly with your hand. For now I'm only giving it 4* until I see how it holds up.
