Can someone recommend a vacuum breaker/anti-siphon that has a less of an annoying hum?

We have vacuum breakers but my dad will inevitably remove it because he can't stand that humming sound. He also insists on leaving the hose bib/valve at all times, even when he's not using it.

I don't want my parents to accidentally poison themselves or us when we visit.

MrZee ,

Your post inspired me to try to fix my silcocks because I too hate that whine.

I looked at the reviews for the vacuum breakers available at Home Depot and, interestingly, I’m not seeing any of the reviews mentioning whine/hum/noise. This leads me to assume that a new vacuum breaker will work fine and that the whine ends up happening when the VB ages (or if you get a defective unit).

I picked up this ridiculously overpriced unit, removed the old one using slip joint pliers, cleaned the threads, applied liquid pipe thread sealant, and screwed on the new one.

So far, no noise. Time will tell whether this is a short term solution or if it’ll last a reasonable number of years.

Note that some silcocks will have fine threads for a VB, some not. Make sure you get the right threading for your application.

If your dad already removed the VB then you don’t have this issue, but for others that might stumble on this conversation: Many VBs have a set screw in the side, which is screwed in and then broken off to prevent removal. Code often requires this. If yours is like that, you’ll need to drill out the set screw before you can take off the old one.

I don’t think they will poison themselves. I had to look up what a vacuum breaker is, never seen one in the uk, and not seen reports of anyone being poisoned due to not having one. Check valves are sometimes used (for water heaters for example) but those are silent.

My dad uses those insecticide or fertilizer things that hook up to a hose. I'm just worried about backflow into our pipes from it

Docus ,

That sounds like a bad idea to me. But a simple check valve should keep them safe i think

MrZee ,

I hate that hum too. I don’t suppose you found any solution?
