Or, solve the problem for good by disabling the anti-siphone with and adapter:

The 1sr one does make sound when the valve is closing. In some homes this can be heard throughout the whole house. For this reason, I recommend the Pro version in the link above
So now that most counties are requiring anti-siphon valves on all exterior hose Spigots, we have yet one more thing that can fail and needs to be fixed.
These basically only serve to protect your home and the city water system from contaminants and debris that in rare circumstances can get sucked back into the water main from the hose or watering system. They are almost completely useless in most situations.
Problems with these valve range from:
~ Strange Noises
~ Water Flowing out from around the valve and Not into the Hose
~ Leaks
If you have a modern house, chances are you have an Anti-Siphon valve already built into the end of your hose bib. They are pretty obvious and easily identifiable by the set screw locking them in place. The main problem is that the hose bibs that come with them have a special threading to accept the vacuum breaker end. Some hardware stores sell a direct screw on replacement for aout $25. Home Depot actually sells a much cheaper solution for $8 which will use part of your existing adapter.
If you have an older style hose bib with a vacuum breaker just screwed onto a normal hose bib attachment…… TAKE THAT THING OFF & DON’T LOOK BACK!!!
