Outside water spigot

[FrankD]

Why does the outside water spigot cause a vibrating noise when using it. Also, I’m using a retractable hose and when I turn it off the water sprays out at the spigot

It's the back-flow preventer

The vibrating noise may be a defect in the backflow preventer. If the backflow preventer moves up and down on the spigot, try pushing it all the way up or down. If the backflow preventer does not move on the spigot, make sure the spigot is tightly mounted to the wall, and the valve stem is not loose. Another thing you can try is to tighten the set screw on the backflow preventer. The spigot shouldn't vibrate. But, it is normal for water to flow out of the holes around the backflow preventer to prevent water from backflowing into your house, when the hose retracts. Good luck.

Spigot Vibration......ok all you rocket techs, removed BACKFLOW PREVENTER, made sure everything was right to the home. No difference.

The backflow preventers are required by law, please put it back on. As for the noise, try a different hose, I am guessing that you have a hydraulic tuner circuit. Let us know if that 'fixes' the noise.

Does it vibrate with the hose detached? If so, it sounds like the spigot is not firmly attached to the exterior wall.

Ours will make noise at a very specific flow rate.

Yes, it's back flow to keep water out of about a foot back into the spigot to keep from freezing if it gets to cold. Everybodies does that, it's a built in safety!

:ho: Back flow preventers are used to protect potable water supplies from contamination or pollution due to backflow. :) I think what you are talking about is a "frost free sillcock"

[retiredguy123]

My spigot does not vibrate with or without a hose attached.

[OhioBuckeye]

CWGUY, yes that’s what I’m talking about but the comment wasn’t real clear then. But the spray when turning ON or OFF does prevent from freezing because it does leave an air pocket about a foot back. Yea, I didn’t think about what you said, thanks for clearing that up for me!

[Mikeodonnell73]

The vibration is probably caused by the 90 degree elbow changing the direction of the water. You can put cotton or something soft next to the pipe where it goes through the wall. The second item is when you close off the hose nozzle the water pressure builders up and the hose isn't as tight as it should be and the joint leaks.

An air pocket a foot back ??? I don’t think so . You’re not going to “push back” an air pocket against about 45 psi (home water pressure)

The shut off on a frost free is positioned about about 12 inches back from the turn off

I took the extra unit between the house and the hose off. Got rid of the noise,. Be careful if you do.,

The $5 dollar back flow preventer on the outside spigots installed by the builder is due to building codes and offer no protection against frost .

The frost free devices are not necessary in this part of the country......

The vibration may also be caused by a less than tight stem valve. If the stem nut is not tight enough the stem valve can "chatter" inside the hosebib. We often find loose stem valves. Simply tighten the stem nut a bit...not too tight or you will not be able to turn your hosebib on or off easily.

This can also happen with two handle bath faucets. Basically, loose stem valves cause "chatter".

BTW, I've never seen a frost free hosebib here in The Villages. They are not needed here. Also, you should not remove your anti siphon valve unless you are replacing it with a new one.

Yea, I think I’m right, the spigot are made just for outside spigot’s, they’re frost free spigot’s so they don’t freeze. I had them in my outside spigot’s when we lived up north. They’re longer, about 10 to 12 in. long.

I had to replace one, one time up north because one of the homes I owned had copper plumbing in it & one of the copper pipes that hooked into this spigot bursted & I had to replace a section leading up to this longer spigot! Yes, maybe they don’t have any use for them in Florida & you can only find them in colder climates. Sorry, don’t want to start an argument!

[DangeloInspections]

No argument at all my friend...life is too short and we are all quite blessed. I am familiar with both. One way to tell the difference is that the frost free ones have a long straight stem, usually between 8-12 inches as you state, so the washer is inside the home away from the cold. The handle is coming out of the home straight...the non frost free ones typically found here are often angle stops, where the handle is at an angle to the house wall. To answer the original question, the chatter can come from either the anti siphon connector or a loose stem nut itself....both an easy non invasive repair.
