I am presently purchasing a home built in 2001. It looks as though I have anti siphon hose bibs, but nothing like I have read being explained by others. This bib seems to have a bronze cap that is added to the bib with holes around the rim where the hose connects. There is a spring and rubber gasket device inside the end.

When I turn on the water I get no flow, if I use my finger to push the little pin like device into the faucet it seems to lift the gasket off it's seat, but I don't get much water flow. It almost seems as though the device is installed backwards, however I doubt it is. Is there a portion of this device that is missing?

Any help on this one from anyone.

Thank you.

It is installed correctly. It allows water out but prevents it from being sucked back into your house plumbing system. When you push on the middle of the anti-siphon attachment - it seals the valve.

Afaroo,

Yes, it looks very similar, but no lock nut below.

It is called a Vacuum Breaker

Hose bibbs or faucets that are connected to a municipal water supply or other drinking water supply should be equipped with hose connection vacuum breakers to prevent water in the hose from moving back into the water supply. Backward movement of water is called backflow, and it can occur either by siphoning or back pressure.

As Milo stated it is installed correctly, just connect a garden hose and try if it works, good Luck

Our inspectors usually over-tightens that lock-nut until it's head breaks. That way, the vacuum breaker cannot be easily removed.

This is a "break away" set screw. It's designed to break away and secure the vacuum breaker permanently to the hose bib. I have removed them by taking a 14" pipe wrench and unscrewing it. The set screw will dig into the brass hose bib body but will unscrew after a turn or two. You may remove and replace it that way. The only other way would be to replace the hose bib itself. Good luck, Tom

If I'm hooking a hose to these fittingings and not getting water flow, I take it both fittings, front and back yard must me bad?

Why do they work with the hose hooked up only?

Thanks

Why do they work with the hose hooked up only?

The vacume breakers we installed on our hose bibs worked with or without a hose attached. Remove one and try the hose bib. Can you get water now? Let me know. tom

[afaroo]

Thanks Tom Sorry my mistake, I just wanted to know if it will work with hose installed, I know that vacuum breaker should work with or with out the hose installed.

Best Regards,
John

John, I was answering Phatracers question. Your description's bang on. Regards, Tom

Are vacum breakers legal on frost free hydrants for inspection for a camp gound in the state of Indiana ?
