The plumber that fit my boiler used silicone on the compression fittings of a magnaclean filter I just replaced. He also didnt bother to de-burr any of the pipes. This is why it makes me laugh when plumbers on forums wont offer any advice and tell you to call an experts and then you do and the expert is a cowboy that does everything wrong. Thanks to videos like this we can do thing properly ourselves!
Its nearly midnight and I've been trying to fit a service valve under my bath whilst fitting new taps. But a simple job ended up with a leaking compression fitting that didn't want to stay dry. Bit of tape on the olive and it's done the trick! Hopefully not just jinxed myself though. Thank you so much brother!
I was always taught as an apprentice, never use PTFE on compression fittings. All that is needed is a light smear of grease or Vaseline on the olive. This allows the two mating surfaces (in the nut and the olive) to compress easier so you will not have any leaks…. Has worked for me over the last 45 years.
@@ron2368 from what I can see, pipe dope is for sealing threads, not applying to olives. I guess it will work, but why buy it when a little smear of grease or Vaseline will work perfectly.
I always use jointing compound on all my joints, it’s so easy and they never leak. Been doing plumbing and other stuff for 20 odd years and compound is the best thing hands down. It removes the issue of human error when tightening olives. I never get leaks. The times I’ve been called out and someone has a leak on a compression fitting because the olive has been over tightened… just a thin smear of the stuff, problem solved. Ptfe is good but can be much harder to apply in awkward situations. Jointing compound is the way.
Jointing compound and my 'grease' solution are the same - it enables the olive to be smoothly compressed onto the pipe. I have never used jointing compound on new pipes with ne fittings and never any leaks!! PTFE is not a solution as it only selas outside the olive so if for any reason the olive is not bedding into the copper pipe - ie if the pipe has a kink - it will not stop a leak.
I have used jointing compound on all drainage pipes and I never have a leak either! I’ll have to try it on pressurized pipe connections and see how that goes, maybe just a smidge
Richard your grease solution has limitations. Jointing compound (Boss White / Boss Blue) allow for expansion and contraction much of the time you can get away with using vaseline but it really isn’t a solution when you have to work in a professional capacity and over time make 1000’s of joints. if the pipe has a kink you shouldn’t use it. Listen to the sound of the fitting as this guy tightens those joints, that’s something you shouldn’t hear except in desperation, in a cellar, when you’re on a tight schedule (and the customer is a bad payer.
@@chrisgee5893 Watching and listening to The DIY Guy tightening the fitting bears out my previous email - modern olives do not have lead lubrication as years ago so greasing them stops metal on metal graunching which prevents a smooth tightening of the fitting. Grease allows a smooth tightening so no need for anything else to ensure a watertight joint!!
My life lesson is to solder everything. I did a whole house filter/water softener setup and thought I’d be so professional and break my rule and make the water softener fittings compression type. Much frustration later, just cut out that section and soldered it. Always takes a little thought on layout for access but it’s solid for a few decades. For sure the brand of compression fitting matters… expensive is machined to tighter tolerances, but soldering and brainpower is cheap. But I’m a very good DIY solderer and I don’t charge by the hour.
I too like using end feed solder fittings as they look neat and hardly visible . However when adding or replacing new pipe onto old pipe I always use compression as old pipe may be a different size, is dirty or wet.
Great video I like how you get other people talking about using pipe dope and grease.I think all the above will work thanks so much.I am just about to start a job and don't think I will have to worry about any leaks.
You actually put the tape on in a counter clockwise motion. I had to watch twice because you said it was clockwise. I guess it needs to be clockwise relative to the threads of the male pipe end facing you. Great video. Thank you.
Thank you for those tips. Could not get the compression ring off so i left the old one on. Weeping a bit, ordered a compression puller and will pull the old one off and use the one that came with the new valve. IF it still leaks i will use the tape as you mention. Keeping my fingers crossed!
I tried to tighten the nut but it didn't work. So I went for step 2, PTFE tape. Undone the nut and water started pouring out. Couldn't stop it or get the pipe back on. Flooded the house took the ceilings down, wife has left me....... Christmas was cheap this year tho 👍
Olive removing tools are much better than hacksaw or a power tool, and arent expensive. When access is difficult for an olive puller, I use an olive cutting tool. Alternatives to PTFE tape are liquid PTFE or plumbers mate compound. I agree that copper olives are usually more malleable than brass ones. Soldering is a bombproof method when done properly, but some areas are risky for blowtorches, and have no access for electric heating devices.
Thanks for the video. I will try tomorrow with the tape. Never thought about. I was getting frustrated already by the tiny leak driving me crazy. Tomorrow new sink goes in so would be nice if it wouldnt leak 😂😂
Well done sir; you seem to be the only one that I can find in youtube land that’s verified my “theory”, PTFE on the olive. I will place some on the male end of valve as well. Thank you mate
An olive, the compression fitting and the pipe are all precision so never any need for ptfe on the outside of the olive. All it does is lubricate the olive so it tightens smoothly. I use a smear of grease.
Joint compound is usually not needed, but is always worth a try if a seal cannot be achieved using thread tape. It's often worth checking to see if the previous plumber managed to put the olive on square. If not, fitting a new olive is the only way forward.
If the PTFE doesn’t work mix some Milliput up & wack it around the joint & smooth it off . It will still set & seal even while the pipe & joint is still wet & out live you . I sealed one 40 years ago & it still holding fast .
Whenever I fit a compression fitting, I give the joint a squirt of WD-40 or the like just before tightening it up, this works really well, you can feel the joint lining up and the olive bite when tightening. Have never had one leak!
@@martinw245 Vegetable oil as bought at all supermarkets do the job so all safe if for drinking water. But as long as the grease (whatever it is!) is only touching the outer edge of the olive and the tightening nut it is safe. The lubricant is ONLY between the nut and olive to make it tighten smoothly.
Liquid PTFE is readily available. Pop a bit on any fitting, compression or threaded. I've been an engineer 30 years and never had a leak on any type of fitting when using it.
This might seam a strange comment ,but up to about 10 days ago, I had a leaking compression joint under my kitchen sink, out of desperation and trying not to remove the sink to get to it,I simply turned down the pressure by slightly closing the stop cock, PROBLEM SOLVED ! 😁😄
When I used to use these compression fittings in the 1970’s, 80’s and 90’s they would absolutely never leak. Now, from the 90’s on, every one of them leaks and need Teflon tape to make a seal. I don’t know if it’s the ferrules or the pipe but something has changed.
I must add after a day's worth of grief, please get your hands on good Teflon tape that is wide. I was using what I had laying around (frequently, plumbing related things you buy will include some cheap plumbers tape with it) I was trying to avoid a trip to the store, so I tried using a few of these rolls and they come apart like tissue and are impossible to maintain their width, they turn into string. So much frustration. Leaking like a sieve. Never again. What a waste of time and effort. Also, you may be working with one inch on either side of the ferrule with no room to use the roll itself to help you unroll the tape, you have to cut a length and work with it loose. I went to the hardware store and got some good tape. It fixed it in five minutes like a miracle. With good tape it maintains it's width and it's easy to do a proper wrap. Dry as a bone. A happy camper.
For a DIYer, I wouldn’t suggest the hacksaw option to remove the olive. If you score the pipe when you break through, you’ve no chance of sealing it then. Personally, I always use a sealing compound on the joint and plumbers grease on the threads. It tightens smoothly without the screeching, but that’s just me.
Thanks I took my 3\4" compression fitting off, Wow it was not even indented into the copper, Than I had to use my 1/2" Racket w socket to tighter it down I mean w all my strength to get it to seat and be tight, I than loosed it off to checked to see if it was it was indented, might be a good video for you to make? The problem was I tightened w Adjustable wrenches but it would keep moving and I was thinking how tight does this have to be? and after seeing your video, it still was not seated , Wow if I had left it this way (I actually had it w water pressure on and thinking something is wrong it leaked) have you ever seen a Fitting come off?
Here in Texas, some plumbers use Teflon tape on compression rings / olives to help ensure no leaks are present (not on the threads). Also, I’ve seen some plumbers here put Teflon under the olive to help keep it in place. I’m not sure if other countries (like Mexico) use metric sized pipes (if that’s a thing). But I worked on a 1/2” pipe one day at a daycare facility. It was a simple angle stop replacement and the 1/2” angle stop I tried putting on was very loose no matter how much I tightened it so I used a sharkbite angle stop instead. I noticed though that The old angle stop I had removed however, had blue Teflon underneath it possibly to hold it in place? Odd but it seemed to of worked for awhile.
Personally I never tighten or loosen such a fitting without firmly supporting the other half with another wrench, so as not to yank the pipes back and forth as seen in this video. Call me paranoid, but I'm always worried that otherwise some other fitting nearby could start to pipe up (pun not intended). Great tips on the PTFE and removing the olive though !
Got a awkward weep on a ½" compression with a plastic thread on a little Triton water heater. Tried PTFE so far, scared to over tighten because it's plastic. Would have been nicer if the ½" thread was designed to be used with a fibre washer. Any thoughts?
I'm a little surprised you don't use an olive removing tool. Given how fast they are, I would have thought a pro would keep a couple in his bag. Is there a problem with that tool that we amateurs don't understand?
I use a crox and hemp grommet never fails most of the time. oh and another problem, brass can get damaged by the water and become weak it usually goes red and cracks easy, if your thing is still dripping even after you have played with it it maybe cracked. google says: Brass is susceptible to corrosion; contact with amine (derived from ammonia) can cause dezincification, whereby the zinc is leached out of the alloy causing weakness and porosity in the metal.
If you buy brass fittings marked DZR, this doesn't happen as they have no zinc in them. This certainly applies in the UK and may elsewhere. Yes I have had fittings crumble in my hands through dezincification. One was on a hot water cylinder and that got very " exciting" shall I say.The fittings were not DZR marked though and that's why it happened.
Is a compression fitting that has worked for twenty years likely to be the source of a leak (soaking my kitchen floor) , requiring tightening/fixing the compression fitting? The issue is my Bosch dishwasher that has a difficult-to-diagnose leak that shows up only after it's cycled through to the end of the wash and dry. The wet stain on the sub floor seems to indicate the only possible leak point is the compression fitting on the hot water line into the dishwasher. All other lines, drains, pumps, seals, etc are OK. It seems peculiar that an old compression fitting would be the problem. Do the experts out there feel this is probable?
If, rather when, you leave a teeny scratch on the pipe after cutting off the olive, will it suffice to carry on anyway by putting ptfe round the pipe, under the new olive?
Tried all these still got a tiny leak out the back of the compression nut, is there a good sealant I could apply to the back of the nut, I've tried plumbers mait and it still leaks
It is interesting that these fittings use an olive. I have used poly pipe for 50 years and unless there is some solid insert inside the pipe then the pipe compresses inwards over time and it always leaks. I have only ever used flared fittings for copper. But they have a problem if the copper is very old. As new the pipe is soft an annealed but over time it work hardens which makes it less effective at sealing. Obviously I have used vaseline grease and other tricks. I can see that if the olive needs to compress and if the material is as hard as the copper pipe then the fit is critical. Should olives always have sealant applied to the pipe before the olive is put on to ensure no gap between the olive and the pipe?
The plumber that fit my boiler used silicone on the compression fittings of a magnaclean filter I just replaced. He also didnt bother to de-burr any of the pipes. This is why it makes me laugh when plumbers on forums wont offer any advice and tell you to call an experts and then you do and the expert is a cowboy that does everything wrong.

What about jointing compound? Just smear a little around the olive on the side to the open end of the pipe and fit in the normal way.
No need for jointing compound on new copper and new fittings. Use grease as a lubricant and no leaks

Always lube these fittings! And then over-tight, release, and final set with ease, not crazy tight!
The best thing with compression fittings is do not over tighten,always leave yourself room to tighten in increments
👍
If you put a drop of oil on the threads it will take the friction out of the join and make it easier to tighten
Thanks that was a of help to me today 😁🤗🤗
Another trick is, smear the screw thread with some Vaseline so that it can be tightened more smoothly.

You only scratch the pipe if you cut your groove too deep. Keep the blade away from the pipe and just cut into the olive and your good
Tried all these still got a tiny leak out the back of the compression nut, is there a good sealant I could apply to the back of the nut, I've tried plumbers mait and it still leaks
ive been a plumber for over 40 years and have never used ptfe tape on compression joints. Always use a potable jointing paste applied to the pipe.
Use your hacksaw to remove 1/8” off the end of the copper pipe. You won’t need to replace the olive or use any Teflon tape.
Love it!

It is interesting that these fittings use an olive. I have used poly pipe for 50 years and unless there is some solid insert inside the pipe then the pipe compresses inwards over time and it always leaks. I have only ever used flared fittings for copper. But they have a problem if the copper is very old. As new the pipe is soft an annealed but over time it work hardens which makes it less effective at sealing. Obviously I have used vaseline grease and other tricks. I can see that if the olive needs to compress and if the material is as hard as the copper pipe then the fit is critical. Should olives always have sealant applied to the pipe before the olive is put on to ensure no gap between the olive and the pipe?
