Hose bib malfunction?

Just curious what might cause this? Gauge is working properly.

Looks like the anti-siphon valve on top is stuck open.


Like Randy said the anti-siphon valve is either broken, missing or stuck open. They dry out after time and the rubber washer disintegrates.


Well it does leak. I’d say that was a defect! :wink:

I just call it out as “Exterior hose faucet leaks under pressure.” Defect
I do see it often.

I’ve never seen this happen before . :grinning:

Thanks Martin

Thanks Randy

Yes sir, Thanks

Under your HI Rules, it does not “function as intended”. Don’t worry too much on the “Why” when it comes to your report. But it is nice to know the why for your own good.
