    • @dazmatic
      @dazmatic 9 месяцев назад +2

      Yeah - learned the hard way. But it was a compression fitting that failed with PTFE, that sealed well but was under tightened and popped off.
      Jointing compound is a bad idea on these because it may seal but might not be tight enough
      Best test is to tighten loosely, no compound, pressurise the pipe and stop if it starts to leak and just tighten enough to stop it leaking and then a few more flats.
      You should be able to undo a fitting and the olive should be able to spin but not move up or down, that's how you know it was just tight enough.

    Glad to see you mention the marking of tightened fittings. It was mentioned to me over 50 years ago as a worthwhile habit and I have always done it. I then go around a job afterwards to check for the marks (bright red is my preference). It has only saved me once but it was in the loft of a 3 story house where the consequences of a leak couldn't have been much worse.
    My preference is to do an initial tighten of the olive with the pipe slightly (~1mm) pulled back from being bottomed in the fitting so that all the tightening force acts on the olive and isn't (after the olive grips the pipe) shared with the pipe pressing onto the shoulder in the fitting. I then open it up to see that the olive is seated happily against the fitting (lots of people don't seem to appreciate that the interface between the olive and the nut isn't sealing anything). I then apply potable jointing compound and firm to final torque and mark it.
    I also prefer copper olives to brass - usually involved bunging out the olives that come with most fittings.

    @cheekycockneychappie9384 7 месяцев назад +23

    For me the best tip I ever learnt was to not place the copper tube hard up against the bottom of the fitting as when the olive grips the tube the nut will pull the tube into the fitting but wont allow a full seal around the olive so prior to tightening the nut back the tube out of the fitting by a couple of millimetre then tighten it up ..job done 👍

    EXCELLENT advice. I am a hydraulic Engineer and I have spent most of my career training fitters how to avoid leaks in high pressure systems. I watched this video to find similarities. Everything you have said is bang on and CORRECT. In respect of under-tightening, we get the nut spun down to the point where it contacts the 'cutting ring' (Our ring cuts into the pipe - slight difference) and we refer to that as the 'fixed point'. That is the point at which all tolerances from threads, tapers diameter differences are allowed for. We then mark the nut and the pipe and turn 1&1/2 turns. That is our industry, yours may differ. We then put a high visibility mark on the pipe and nut. Before start up, all visual checks can be made easily. GREAT VIDEO

    Cheers ... Jointing compound.. need to find that. But I always put a wrap or two of PTFE tape on the olive of new fittings, just in case there is a small discontinuity (Roger, Skill Builder tip).
    Another tip I find useful is clean the pipe before fitting, with fine grit sand paper or one of those cleaner wire brush tools. can make a difference.
    Lastly another over tightening danger: stress can build up in the nut then one day it might crack and all hell will break loose when least expected, has happened to me.

    Excellent video - so glad I watched before attempting to use compression fittings.
    Quick question - can you still nip up a compression fitting that has jointing compound after it’s been in place for a week, or does the compound go off and crumble if you try this? I thought I’d tightened it enough, but after a few days it started to seep (not condensation).

    @anthonywilson4873 9 месяцев назад +6

    Make sure pipe fits and correct length, make sure both sides of the olive are on the pipe by giving it a nip and visually checking it. In tight spaces, I have used a fitting away from the joint to give the olive a squeeze so it cannot move. A few wraps of PTFE tape around Olive or potable water sealing paste where applicable and no problem. You are posh poetable water I have always said potable water (Drinking Water). Not to tight not to loose and never ever think your brilliant and do not need to double check everything, it will still get you every now and then. The amount of experts I have met in life at all things who cock up all the time because they know they are perfect and do not need to check! Everyone can get caught every now and then so check check check. I stripped and assembled a hot water tank bottom fitting three times resealing each time and it still leaked to find at two o’clock in the morning a cracked reducer fitting, I had used the old ones! I had purchased new ones but the old fittings were ok (Not). It was a home job as well.

    I was once told by a plumber that the manufacturers spent £millions on R&D to get compression fittings to seal properly, so under no circumstances do such a stupid thing as put anything on the joint. Stood me in good stead for donkeys years. A fitting that's been overtightened to the extent that it leaks means removing the fitting and a section of pipe and starting again.

    • @MrChrissy1r
      @MrChrissy1r 4 месяца назад +18

      That may have been the option decades ago, but today 2023 the pipe and fittings as mentioned are imported and they're crap, they need all the help possible to effect a good permanent seal. Copper pipe made in the U.K in the old days was much thicker walled , and like for like fittings old against new weigh significantly less, thus there is that less brass. In practice I might add, I would far rather act on the advice of a working modern day plumber/heating engineer than and old fart that is decades out of touch! As for manufacturers spending millions on R&D, not these days especially imported stuff, it's cheap and cheerful to maximise profits.

    I frequently remove olives by driving them off using the compression fitting's nut. Just open your adjustable a bit wider than the 15/22 mm pipe and tap the back of the nut with them. That's assuming the fitting hasn't been overtightened. The olive should pop right off, and if you're in trouble, you might even be able to re-use it 😱😅

    No PTFE at all. One thing which not mentioned is what I always do. When first sliding on the olive and entering it and the pipe into the fitting is just before tightening, is pull the pipe out about 1/16". Reason for this is, if you need to remove the pipe later for whatever reason and refit it the pipe will not bottom out before the already compressed olive

So i changed it to nice straight lengths of copper pipe, brand new olives and fittings etc. I sent a pic to the plumber just to show if ive done the right thing (he is a friend as well just to see if ive done it all right) and I said i also used the fernox potable water jointing compound around the thread and also on the olive and he said I didn't need to use it at all because it was new fittings and to not really use it for new fittings.
    Just wondering if this is the case for any plumbers here? Like is it only for use on an existing fitting thats been fitted and is causing a leak, is it bad to use it on new fittings?
    I personally found it good to use because of the way everything was awkward to get to, it was easier to apply this than to wrap around tape and when tightening the fitting it seemed to then unscrew the connections to the tap that could only be screwed in by hand! So the compound helped me not have to tighten everything super tight, also as a diyer it takes a while to know when enough tightening is enough so its a slightly few less turns with the stuff applied to give it a watertight seal, making it ok to give it a bit more welly if needed instead of overtightening.
    I wanted to do it right as I had caused a massive leak before with the connections to the bath taps, I overtightened the speedfit to metal thread connection and it eventually cracked after a few months, water pouring downstairs XD
    So since then ive avoided eBay taps and overtightening lol

    Olive tip I was taught by an old school.
    If the olive is just so put something hard being it and tap firmly the other side and it just slides off.
    This really works.

    Hi I'm a sparks and if you remember MICC cables which have a similar olive and gland system I had the same thing educating apprentices on not over tightening the olives because if they were over tightened and the cable was moved you lost a good earth as the outer sheath was the earth. Brilliant vid and good tips. I looked for the olive splitter that you sowed and could not fine that particular one. I would like to add that to my plumbing kit. In the past I have used a junior hacksaw very carefully to remove an olive not quite cutting through.

    • @gasgas2689
      @gasgas2689 2 месяца назад

      There is another type of olive cutter that looks like a large pair of pliers. One of the 'cutting' jaws of the plier is flat and you insert it inside the pipe. The other 'cutting' jaw is indeed a cutter and cuts the olive. The difference between the 'plier' type and the one shown in the video is that the 'plier' type is operated in line with the pipe instead of at right angles to it.

    Hold tight!! I had a questionable olive that I wrapped in PTFE tape about a month before this video came out. That and a little dan of Megalok, for lubrication, did the trick. Solid pipes on an old wash basin did not give much wiggle room.
    What is the tip for cranking them down right? Can you feel the olive start to engage? I tried snug, plus 1/4 turn. Still leaked. I kept the water on and stopped 1/4 past when the leak stopped.

  • @replevideo6096
    @replevideo6096 9 месяцев назад +4

    The problem is actually the crappy olives which come with the joints. I'm not a professional but I have been doing odd plumbing jobs since the 1960s. Compression joints were never a problem then. You just screwed it up finger tight then gave it a quarter turn or so and you had a joint that would never leak.The olives were a very soft gold coloured metal. Today the olives are a harder more copper coloured metal. I always now use PTFE tape as you describe or at least one joint will leak and will not seal. I went into an old shop about 15 years back and they had a big box full of gold coloured olives so I bough a handful. After that I did not need any sealer until they ran out.

    • @jts8919
      @jts8919 5 месяцев назад +1

      you can buy pure copper olives (vs the brass ones which come with the fitting) - guessing these are the ones you are describing (they are softer and more reddish in colour than brass)

    Very good advice for non plumbers like myself.
    I usually cut the olive off with a hacksaw blade as you suggest, and carefully.
    Presumably leaving the previous olive on is not a good idea?

    • @roycraggs2058
      @roycraggs2058 8 месяцев назад

      You can remake a joint with the old olive in place, if you cant remove it. Just reassemble the joint after applying jointing compound or PTFE tape to the olive.
      If you are a regular plumber, then olive removal tools arent too expensive to add to your kit.

    If I put compound on a compression it was an instant fail or a rap across the knuckles with a pair of sixes. North Thames Gas apprenticeship. 4 year apprenticeship, 18 years working. How times have changed. Surprised you did not say LS-X, a must on them fooking doughnuts :) Also under tightening is always better than over, as you can always nip it up, over, no chance.

  • @gasgas2689
    @gasgas2689 2 месяца назад

    It might be worth mentioning that over the years, a compression joint might loosen with constant heating and cooling of the joint. You can come back to a joint that was tight when installed and it just undoes with little more than finger pressure.

    I've always used jointing compound but just a thin trace, not like icing on a sponge cake. And put some on the pipe before sliding the olive on because you're then sealing another potential leak point.

  • @mandipchaggar1885
    @mandipchaggar1885 9 месяцев назад +5

    With particular reference to gas - compression fitting where used must be ‘accessible’ ie not hidden within boxing or under floorboards etc.
    Where they are used say pipe work serving a hob, the compression joint must be done dry from what I was taught in my gas course. Reason being a joint done with paste may well pass the tightness test at the time or work but may cause a leak later on where the paste was actually filling in a leak and the paste has dried out etc over time

      Just what I was told on very recent course - nothing extra to be used on compression type fitting, if it’s a gas carrying pipe. Fine to use paste, Ptfe on olive if you like on water, but it shouldn’t really be necessary.

    Olive cutter. Very nice. I'm not a plumber, but have been doing a bit of water work DIY. Definitely had issues removing or not olives. I fancy a cutter, or maybe the hacksaw and screwdriver tip.

      You can get olives off using an adjustable spanner which you adjust to the diameter of the pipe. Put the spanner opening onto the pipe behind the olive and then gently tap with a hammer. This drives the olive off the pipe.

    Never knew this... but as an insurance policy I always smeared some plumber's putty on the copper pipe before sliding the olive onto it, then I would also smear the olive with some more plumber's putty before bringing the nut over it and tightening the nut (holding the other part of the fitting with another spanner) to fully compress the olive and form a strong watertight seal - I've never had a leak ! lol

      Only use for plumbing putty is what it is designed for, sticking glass panes into windows. Sealing compound works better, and you can at least undo it later on without needing to cook the putty out.

    Another tip I think you should have mentioned, make sure when you place the nut and olive on to the pipe, you make sure the pipe has entered the the full depth of the body of the fitting, I have seen some that have only just nipped at the end of the pipe, and could pull apart!

      I always tighten the nut and olive dry then loosen it and then apply the jointing compound and then re-tighten that way the compound doesn't get between olive and pipe making less likely to pull off under pressure, this more likely in larger pipework

    • @bbarnes4852
      @bbarnes4852 9 месяцев назад +8

      I disagree! If the pipe is fully home then once you start tightening the fitting and the olive starts to bite it pulls the pipe down with each turn. If the pipe can’t move the same distance of the threads the pipe bulges inside the fitting as it’s compressed and will leak. I always push the pipe home then back out 2 or 3 mm so there’s room. Never needed jointing compound. This should be tip no.5!!!
