Ahh I see. I am unfamiliar with this feature.

My granddaddy method exactly the same….turn off the water let the hose empty.

This is exactly what I do! It works 100% of the time.

They are to prevent back flow. Years ago a man was spraying fertilizer through his hose and turned the device off. Went into the house and drank water from the kitchen sink directly over the hose bib. Guess what occurred?

Attached my garden hose with hose-end spray attachment shut off. Turned on the water supply to pressurize the hose. Turned of the water supply. Got a bath. Your advice besides being snarky is WRONG!

My guess: Absolutely nothing.

Sorry, but this sounds too much like an urban legend. I am ready to stand corrected if a link can be provided.

I removed the anti siphon on the spigot and replaced it with the same thing. It was not super easy to get off as I believe it was/is customary for the installer to tighten the set screw and then break the head off. I soaked it well with WD40, then held the spigot body in place with a wrench while using another to un thread the old valve. The threads appeared unharmed and the replacement unit doesn’t leak - I had both a steady leak and the proverbial shower issue.

Thanks.

Interesting. It is designed to relieve pressure through the holes that you see in the picture. It is the escaping water that causes the shower. I wonder if it can be tightened enough to prevent it from working properly. I wouldn't think so but...

If you don't get the shower then it is not relieving pressure - does that mean it is not functioning properly? After you shut off the water is there still pressure in the hose?

[Spartan86]

Both of my spigots would “shower” even with hose nozzle full open. Now, I am using the collapsible hoses that do naturally “back pressure” a bit as they collapse. I simply assumed the spigot valves were basically check valves that failed. So far that analysis seems to stand in my situation. Also as said I had a lot of leakage at the spigot while using the hose which is not the case any longer. My valves were 2019 installs - they don’t make em like they used to.

Victor, I could be off my rocker, but I have assumed them to be check valves. Under normal ops, the 60ish psi water pressure allows flow to hose. With the spigot valve off, residual water pressure remains in my hose until relieved at the nozzle. With new valves - vacuum breakers - I get no leakage/relief/dripping at all at the spigot. Mine now behave as if there were no vacuum breaker at all. I contemplated not replacing them but ultimately did.

[Spartan86]

For what it’s worth, the AI answer is:

A spigot vacuum breaker should not leak water constantly, but it might drip slightly under certain conditions. Here’s what to check:

- During use – A few drops while the water is running is normal.
- After shutting off – A small amount of residual water may escape briefly.
- Persistent leaking – If water continuously drips or sprays from the vacuum breaker, it may be faulty, worn out, or have a bad seal.

Re-read post # 2 . What you said is not what post 2 says.

Personally I prefer the quick "washdown" since I'm normally sweaty from working around the yard and it's a rather exhilarating and welcome "surprise".

Turn the water off, drain the hose.. what's the fuss ?
