## Description

SpigotMaster Fixes Your Leaking Vacuum Breaker Once & for All!External vacuum breakers on outdoor spigots often fail prematurely & leak water excessively, especially when you have hard water, are using an irrigation timer, or have a need for an always-on water connection. Unfortunately, most spigots have special vacuum breaker threads you can't attach a hose to if you remove it. Also, vacuum breakers often have a set screw that is either corroded or broken off, making it difficult to repair or replace.SpigotMaster to the Rescue!Every SpigotMaster adapter is precision machined in the USA to very precise tolerances.

## Questions & Answers

**Q: I'm confused on which one I really need... I was able to remove the arrowhead vacuum breaker that i can't find anywhere locally....**
A: We can help. Take a tape measure and measure the outside width of the threads on the spigot (with vacuum breaker removed). If it measures 1-1/16" or less, you need the SM01.
If it measures 1-1/8 or a little over, you need the SM01.125.

You can also just measure the inside threads of the adapter you removed. It will measure 1" for the SM01 or 1-1/8" for the SM01.125

**Q: Hello!  i took calipers to the male threads coming off of my nibco classic pro faucet, and it's measuring at 1.24.  i'm in the us, is sm-xxl right?**
A: SM-XXL ~ Fits Watts NF8 EDP #0061854, NIBCO & Other Spigots Where the External Thread Diameter of Spigot Measures 1.3". Internal Diameter of Adapter is 1.25"

**Q: can the Spigot Master be screwed  onto a installed back flow adapter**
A: No. It's designed to be screwed onto the spigot once the Arrowhead back flow adapter is removed.

**Q: 1 1/8 seems to be the thread size. Your 1.125 is just to big but according to your information, your 1.0 might be too small. Do I exchange for 1.0 siz**
A: I thought the adaptor I ordered was the incorrect size. But then I carefully, very carefully, alligned it up and it screwed on perfectly.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5 Stars for the product, 10 for the customer service!
*by S***F on June 16, 2025*

If I could give 10 stars I would!I'm in Hawaii and moved into this house that had a outdoor faucet that was just a tad too big for a regular garden hose so I figured I'd go to a hardware store and find an adapter that works with this spigot, simple right? Wrong! Every hardware store I went to didn't have a compatible adapter, so I called a plumber who actually told me I'd need to pay $400+ to get the faucet replaced because it's such an "old size" and I wouldn't be able to find anything that fits it. Naturally I thought that was utter bs, so I turned to Amazon and figured I'd just buy every size adapter possible, assuming one of them would work.After I made my order, the seller reached out to me, saw I was ordering to Hawaii, and with their expertise, consulted me on which adapter would most likely be the correct size for me. I sent a picture of the faucet to the seller to confirm and their intuitions were correct, they then proceeded to refund me for all of the incorrect size adapters I ordered and only send the correct one, which is the 01.125 size.Between the excellent customer service and quality craftsmanship of the adapter (that fit perfectly by the way, no leaks or issues once screwed in) this seller and their business deserves all the accolades! Huge mahalo!

### ⭐⭐⭐⭐⭐ LOVE LOVE LOVE THESE!  High quality and works great!
*by B***M on June 16, 2025*

In my extreme hard water area, the anti-siphon vacuum-breaking spigots last about a year, then clog up with deposits and leak constantly. These are are excellent solution! Check the make and model of your spigot, to make sure you get the correct part. These are high-quality, heavy brass, with nicely cut threads and a thick washer. I used yellow Teflon tape (for gas lines) and the connection was absolutely leak free. Very easy to install, once the anti-siphon part was removed (that was also easier than I expected). No more intermittent spurting of water, and no more constantly leaking anti-siphon valve. My house is old enough that the anti-siphon type is not required, if they're required where you live, save the parts you take off, just in case. I'm looking forward to seeing the next water bill to figure out how much water the anti-siphon valves were wasting. I would definitely buy these again. Great quality, and made in the USA. Well worth the price.

### ⭐⭐⭐⭐⭐ Exceptional quality product and the *BEST* customer service you could ever ask for!
*by I***. on June 21, 2025*

EXCETIONAL customer service! I truly can’t overstate this. My outdoor spigot didn’t have a release valve and none of the release valves at local hardware stores fit. I’d been looking around for over a month and was getting nervous because I just planted my garden and had no way of attaching a hose. I decided to take a random chance and order what I thought would be the correct size based off the measurements I took from Spigotmaster.A day or so later, Rob at Spigotmaster contacted me and asked me to take a picture of the spigot since the size I ordered was unusual. He found me the correct size and refunded me the difference because the first spigot was significantly more expensive than the size I needed.The quality of their products are excellent and but their customer service is truly the best. I would highly recommend them to anyone. Rob, my garden thanks you! 😊
