Very helpful Thank You
Straight forward. Thank you.
Had that exact same vacuum breaker. Used a hacksaw to create a slot for a flat head screwdriver. If you notice there is a groove already there that’s perfectly centered on the set screw. I removed 2 today easily.
A perfect example of how consensus standards (i.e., the "plumbing code") are little more than tools for entrenched special interests (e.g., plumbers and plumbing supply companies) to milk consumers through government largesse. Why would you mandate installing a piece of equipment that is virtually guaranteed to fail and be deliberately so difficult to replace?
There’s nothing difficult about replacing this. I drilled mine out.
Fully agree, a real stupid code.
Mine are bad. Forgot this but the fiasco I had years back with my porch faucet I simply replaced the faucet. Just dawned on me my faucets are 7/8 not 3/4 soy backflow is 78 with 3/4 MIP. They were crimped on, so set screw. Now I need 4 so looking at nearly 15-20 per backflow vs the 3/4 for 8 bucks. It is cheaper to simply replace all with a new 1/2 Fip x 3/4 MIP and get a set of 3/4 preventors. Weird thing is I do new home work and most new homes done have a backflow on taps, only the sprinkler system. Guess mine, 16 years ago didnt have a sprinkler system, added later, so it jad to have backflow devices on all taps. I cut one off today and I thing this 7/8 tap was made with a preventor on it.
thank you. I bought the same exact tool but it didn't work like in this video. I ended up just drilled the little rusty pos. Thank you!
Make sure you follow the instructions on direction of drill - the first bit is designed to make a small hole only and then the second is to “bite” into that hole. They go different directions.
You can probably re-try with the next bigger size if you didn’t drill too far in.
Thank you for the video. What size extractor did you use?
I used the smallest one in this set (speed out#1) - it states for #4-#7 screw sizes. Perfect size for the job
@@ystebadvonschlegel3295 after I saw your video I ordered from amazon a set of extractors. All DIYers should have that in their tool box. Thanks again.
Yea, I just drilled out the screw stub that was in there then a squirt of WD40, and the whole thing unscrewed. Did that on 3 of those buggers. I will not be replacing those idiotic contraptions. Boy what a mess if I had to replace the whole spigot. It is sweated on. I will only call a plumber if it was my last resort. Who ever came up with those.and why?
Do we really need to keep this thing on or would it be okay if I don’t use any backflow preventer with my garden hose?
Of course I can’t reply to “need” that would depend on your local code. However do educate yourself as to why they are installed. If you ever attach any chemical sprayer at all to the end of the hose and don’t have one you definitely can back flow that into the water supply.
In my case this particular faucet is only used to wash cars with a pressure washer so I did not replace it. When I sell the house I will replace it to meet code.
, our set screw is on the backside, so I don't have access for a drill. Any recommendations?
In that case something like a fein or even a dremel to saw through the actual brass but be VERY careful with eye safety due to risk of metal fragments and go slow so you don’t damage the underlying threads. But cutting through and then using channel locks to pry a bit of space will get it off. I did that version in the past before I tried this extractor
Ok your little screw has a hollow hole in it. Mine doesn’t. Will that bit tool thing you’ve linked still work for me? Sorry if that’s a dumb question.
It will drill out any screw or bolt. The hollow hole is the part that breaks out because it's designed to keep you from removing it. Yours may be slightly different but if it's a screw the remover tool will back it out. You might just have to be a little more careful in holding the drill and starting carefully to center it. Best wishes.
@@ystebadvonschlegel3295 i wish I could send you a pic of what I am looking at! We built this house one year ago and this thing sprays out like a geyser every time I turn off the hose (even if I don’t have a sprayer attached at the end of the hose). It’s ruining the siding on my house. My little broken off screw thing is completely flat. So I just drill right on the flat part with this bit even though it’s isn’t already hollowed?
@@CBull015 Yes - yours does exactly what it's "supposed" to do. And yes it's a metal drill bit and that is likely soft brass. So long as you have a steady hand and go slow it will work fine. You are drilling a new hole with threads and so then the other side will back into those threads and then back the screw out. Just make sure the bit size you choose is smaller than the size of the screw you're trying to remove - if you drill past the threads into the surrounding metal it won't work.
Gosh thank you so much!
what part did you get to put on after you removed the anti siphon?
I can’t tell from the video what end is the extractor I’m old and my eyes are bad.Could you show or tell me which is which
To use the extractor kit the drill is ALWAYS in reverse mode. The end that looks sharp and pointy with a straight sharp line is the drill out side and is used first. The end that looks like a screw with threads and a somewhat flat top is what you use to actually back out the screw. You can see both at 0:26 the drill is on the bottom (use first) and the extractor is on top (use second and SLOW) Remember both times the drill is going in reverse. And when you remove the screw you do it SLOWLY - #1 reason for failure is stripping the screw out by going too fast. If your drill has driver and drill mode make sure you use driver (SLOW) mode for the extraction bit. Cheers and good luck!
That's so annoying I waste more water from the faucet than what I spray out, is it because it defective preventer or there meant for water to gush out
It’s mean to gush out but generally only when you shut the water off. If it’s coming all all the time you definitely have a defective valve so you could replace it or if you want you can do what I did in this video, with the understanding that you are defeating a safety feature and that it might not meet local code.
Okay. Mine started leaking water and needed to replace this. I called up a guy who had a similar extractor but he ended up breaking the bit. Basically the drilling worked but couldnt extract. Anyway he ened up using dremel cutter to cut and remove the broken screw. Oh my ...i can understand its important to keep them on but why u have to break the screw. Jeee
The screw is broken off because the all wise government doesn’t wish the average person to be able to remove. Common good vs individual freedoms colliding. I can see both sides - if you remove and don’t understand why it’s there it’s true harm can be done no only to yourself but to the neighbors. So it’s the cost of attaching your home to the public water system I guess.
Okay. What do I do now Mark?
I tried with the screw extractor, for some reason it’s not able to drill the hole in that screw
Make sure it’s turning the right way and that you use the right end - one is the extractor and will not drill but they look similar . One other person posted the same problem- it’s always worked for me
@@ystebadvonschlegel3295the drill side is the one with more aggressive edges right . I used the drill in hammer mode in counterclockwise direction(arrow facing backward button). Let me know if I am doing something wrong
@@kushagrasingh7731 you definitely do not want hammer mode and re-read the instructions and pictures if you bought the kit I used. User error - it happens.
@@ystebadvonschlegel3295 ok thanks
So, what can you do when you can’t access the screw to drill it??? The code should allow access to the screw!!!!!
If the screw is on the back or not reachable then probably the best bet is to get a hacksaw or fein type saw and cut the brass outer ring itself and then pry it back. I've done that too and you have to be careful not to cut too deep and also be very careful because metal shavings in the eye can cause permanent eye damage (safety glasses a must and proceed at your own risk). I've not seen them installed behind because it takes a screwdriver to drive the screw in before it's broken off on install, so generally they are on the right side because most people are right handed.
Just tried this. Wasted money on extractor set. All you need is an 11/64 drill bit. Go slow and you will see broken screw come out. Stop and wiggle valve with channel locks and it will come out. After a couple of turns. The one I took out was put in 15 years ago. The extractor was ruined.
Hmmm. Glad you got it out. Drilling all the way down to get the entire set screw down would be more likely to damage the faucet but glad you made it work. When I’ve broken extractor set bits in the past it’s usually been that I was going too fast. Cheers and thanks for the reply.
I used drill bit, I don't know the size.
I put WD-40 and was so easy to extract the broken screw and the backfkow.
Thank you for your suggestion.
Or just unscrew the spigot from the wall and screw a new one on for $8
Mine definitely do not just screw off, but if that's an option with how yours is attached sounds like a great idea.
They twisted it so it is facing the wall and broke it off....
Those dirty dogs. Sometimes you can wrench it enough before it catches on a thread to get to it with the drill. Otherwise it's the Dremel technique probably - WEAR EYE PROTECTION!
You can saw through the actual brass but be VERY careful with eye safety due to risk of metal fragments and go slow so you don’t damage the underlying threads. Basically you cut two slots separated by maybe 1/4-1/2" and then pry the slot inbetween back. But cutting through and then using channel locks to pry a bit of space will get it off. I did that version in the past before I tried this extractor
this did not work. Not sure what sort of whussy backflow preventer is being used here. Reverse drilled like hell and couldn't get it out. Also broke my batter powered drill; think I put the speedOut drill bit too far down and it drilled into my batter drill. New drill only the first time using. This video cost me $60.
I'm really confused how you could have harmed a drill doing this procedure. If you watch what I'm doing, everything is pretty slow and minimal. The first "hole" drilled is pretty shallow and the actual reversing bit I specifically tell you slow and easy. The only thing I can think is you didn't have the square part of the shaft of the bit gripped in your drill chuck properly. While I suppose that might cause some damage, proper operation of tools is always important. And this back flow preventer here is solid brass, I did 4 of them - one which I couldn't reach with a drill and had to use the reciprocating saw technique which sucked. Anyway sorry you had a bad day trying to fix something at home, I know that can be frustrating. If it's still there double check you used the correct side of the drill bits (using them backwards will certainly not work) and unless you drilled really deep you could potentially try again with the reversing bit.
Tis product sucked. The drill end wore down as did the extracting end. In its place I used a dremel tool and carefully cut an X over the screw. cuts were deep enough to pulverize the screw and with a wrench I twisted and removed the antisyphon piece. The spigot sustained no damage. But if you do this, be patient and be careful. Replace the antisyphon with a new one but DO NOT use the screw that came with it. Instead tighten it by hand and be careful not to remove it when undoing the hose.
Very strange - have had a couple people say similar things. I’ve used mine multiple times over the years on multiple screws including the project above done on several back flow devices and never had a problem. It’s hardened steel, and the speeds used are very slow so no clue how it would “wear down”.
I have also used the dremel approach and it does work as I note in the video but you have more chance of metal shavings in the eye so please use eye protection (not just glasses) and be very careful! Glad you got yours fixed!
Quality of this item was really bad. The drill bit was not hard enough to drill into anything made of metal, and naturally can’t achieve what it’s designed to do.
Interesting. I’ve used it on multiple items with great results. Are you sure you used the right one as the drill - remember there is an extractor bit and a drill bit. And also remember you have to follow instructions on direction of rotation.
This tool did NOT work for me and I returned the set to Amazon. You notice HIS broken screw already has a HOLE in the middle. Mine did not and there was no way that tool would drill into the broken screw body. I spent a lot of time thinking I had done something wrong, then called a friend of mine who does plumbing work and he said "Don't waste your time, just use a Drimmel and cut around both sides of the screw and break it off with pliers. This is a deceptive video in my opinion.
I think your comments are over the top and "deceptive" is clearly not appropriate. I have used screw extractors to drill into bolts and screws many times and it's exactly what they are made for. If you break off a bolt in an engine block and its flush on top guess what you use - one of these. I suspect you didn't proceed with SLOW drill speed as I suggest and with enough stability on the drill. Like any other attempt to drill metal it's the start that is the key. Using a very small bit to make an initial hole then a larger extractor bit to back out may be a good technique for those that can't steady the drill in the center. If it starts "walking" it isn't going to work.
There are many ways to accomplish the same goal and Dremel and pliers are an option which I also note in my video. But you run more chance of damaging faucet or getting metal shavings in your eyes (wear SAFETY goggles, not just glasses if using a Dremel on brass please!). This method works but you do you.
This video is not deceptive; it saved my sanity! You cray
