I've been plumbing my whole life, literally, my family are plumbers and have had a plumbing company since early 60's, I've RARELY had a reason to remove the ferrule. The pipe is almost ALWAYS deformed from the ferrule "bitting" into the pipe. I've changed 1000's of stops without changing ferrule, never had a leak.
Unfortunately you neglected to mention any cons. Especially when it’s been over tightened. The ferrule ring digs into the pipe. As you pull it off the stub is now to thin for a new compression valve
True. I score them with a mini file, put a slotted screwdriver into the notch I created, and twist. Of course I have to be very careful not to score the pipe.
@@aredditor4272 he wasn’t saying it’s too small for this tool to use, he means that the pipe itself will now have an indentation where it has been crushed from overtightening and a new ferrule will not sit correctly on it to form a seal. Whether you use this tool or cut the ferrule off, the pipe is unusable. I don’t get why those valves are made to connect so close to the wall that it’s virtually one use and then done if it’s over tightened. It would be better if you left some pipe available in case you had to cut the nut and ferrule off and then you can use undamaged pipe for a new nut and ferrule
@@daleprosser350 the main problem is it's unlikely the existing ferrule will mate up with the new valve, as it was already press formed onto the old valve. It sometimes works, but not often. The machining isn't that exact, especially among competing or newer valves. It's possible that a new valve and ferrule will sufficiently mate to the existing pipe. Personally I don't like to chance it, and solder a fitting on. That can be a problem as far as the valve being exactly where it's wanted after it's been tightened. That's why compression fitting valves are desired on new work, the valve can be oriented exactly where it needs to be. Before I mostly shopped at home improvement chains, I had a better chance of choosing a compression fit valve that would work with old work. Now I can't be bothered to see if I could stock variety for every situation. I'm not strictly a plumber, I'm mostly doing every trade on a 172 room hotel.
Thanks for the heads up on the tool. Didn’t know it existed. Looking back as a retired plumber I had tried using the existing furrule. It was a 50/50 chance it would leak for the reasons you stated. I always wondered why the plumbers doing the original installation didn’t leave a bit of copper pipe for valve replacement down the road. Probably they wanted a cleaner look. At any rate if the valve has to be changed there’s not a lot of choices. I’ve cut the nut off and the furrule. Not a fun job but it can be done. Need to really take you time. If the furrule has been over tightened I try to placed the new furrule slightly away from the groove if possible. That usually works. I always use pipe dope on the furrule. If that doesn’t work solder a coupling on without starting a fire and a short piece of copper. Not pretty but the valve is on. Lastly cut the wall and start from there. I’m glad I retired.
I like pulling off ferrules with a similar puller OR using a tiny Tim to cut off the ferrule when a handyman over tightens the hell out of them. Also lately learned that a little bit of dope helps seal it so you don’t have to over tighten.
Never had a problem reusing the nut and ring .. A little plumbers tape on the new valve will insure no leaks . . Done hundreds of toilet and sink valve replacements....
Okay, I have used this several times, but... What about how it deforms the pipe... the ferrel may be deformed if you try to reuse it, but the pipe always gets stretched and deforms a bit. Cutting is risky too... every removal method has a drawback.
Do you prefer this kind over the "Ferrule blaster" gun-style? I recently bought a ferrule blaster and I actually find it very difficult to compress and IMPOSSIBLE with one hand... what are your thoughts on that style?
once you use compression ring on copper it dents pipe that tool is useless leave old nut and ferrule take t2 pipe dope put little bit on face of ferrule not threads and install valve cause will never seal did you see the pipe after you pulled it i did
Are compression valves "hack"? Can any plumbers answer that for me? I do occasional plumbing work at home ( I'm an electrician) And I've always heard that they are junk. Pros thoughts?
