We are in England! Not Scotland, even though it’s easy to make that mistake with weather like we’ve got today. that’s millilitres for you people who don’t work in imperial. We’ve had 30 mil of rain overnight Which made me think that we need to do a video on how to fix compression fittings. Now, as you know, we’ve done a video a long, long time ago about how compression fittings work. That’s great. But what about if they leak. So we’re going to have a look very quickly if you’ve got a weeping compression fitting, how you can fix them and what you can do to solve the problem. So let’s go and I’m going to get soaked whilst doing this! Hold tight. So then, as we all know, compression fittings work in a really simple way. If you want to know how go to our video which has a very brief description. We’ve got an olive, a tapered insert here, and a nut with a taper on the inside. When they tighten up those 2 tapers work on that olive and compress it on to the pipe to create a watertight seal. So, what do we do if this is leaking? First thing’s first, if you think that you’ve got a leaking compression fitting like that. The first thing I would try and do is see if you can actually nip it up a little bit. Get yourself a pair of grips to grip the inside part here, the actual main body of the fitting. And then use a pair of adjustables to tighten it up. Let’s go! When you’re using grips always grip in the opposite direction to where you are tightening up So, this would be wrong. To tighten this fitting up, the grips are the wrong way round. So you want the grips to be this way round like so. Then you can get your adjustable on the fitting like that and tighten it up. Give it an extra nip. Often that will stop a leak on a compression fitting. Sometimes though it doesn’t. After you’ve done that, get yourself some tissue, wipe it down, fill the system up or whatever you’re working on with water again and test for leaks. If you still find it’s leaking, there’s about 3 or 4 other things we can do to perhaps stop this fitting from leaking altogether. So the next thing we could do is actually strip the fitting down and you will see then that you’ve got a nut with your bitten on olive nut with your bitten on olive,if you don’t want to change the fitting and if you can’t change the olive, you can’t get a hacksaw or something like that, there’s a couple of things you can dothat might seal it if you don’t want to change this olive the first thing i would do isuse some jointing compound this is pretty old jointing compound but it’s going to do for demonstration purposes today, so get yourselfsome lovely jointing compound all this is is linseed oil and chaulk and you get your compoundand you splodge it onto your fitting and then useing your fingers so you get it on nicely like that and then pushyour fitting back together again and tighten it up as you would normally. If you haven’t got any jointing compound you can also use PTFE tape. Right so we’ve got our olive here and remember this is only if you can’t change the olive or the fitting. A little bit of PTFE tape, now,PTFE tape is pretty cool stuff! There’s a knack to useing it try and have your tape coming out at this angle like this, lay it across the olive, with your thumb, Just wrap it round, front and back of the olive, just like so, Make sure when you put the PTFE on the olive that the PTFE winds in the direction that the nut tightens up. If it goes the other way you’ll find that the PTFE splurges out and you won’t be able to seal the leak. So now you’ve got a nicely covered up olive there. Push the fitting back together, and then tighten up. I have never in all my years of plumbing had one of these leak after doing PTFE around the olive. So what if you’ve done the PTFE, or you’ve tried the jointing compound, and it’s still leaking? You are probably going to have to change the fitting. But sometimes you can just change the olive. Lets have a look at how you change the olive. The Way to get an olive off if you don’t have an olive splitter you might as well use a junior hacksaw and a very steady hand. Because you do not want to score the pipe. The good thing is you can get a junior hacksaw cut diagonally like this across the olive but before you actually cut fully through the olive, you can get a nice little thin slotted screwdriver and twist the olive apart, and be easily removed from the pipe. So, get our hacksaw blade across the olive and just gently start to saw Try as best you cannot to score the pipe. Now you should be able to pop your screwdriver in there and remove the olive. Now looking at the condition of the pipe, it’s not too bad. At this point you can have problems that may mean replacing the pipe If there is a slight ripple in the pipe its going to be very difficult to re-seal that bit of pipe. This piece looks OK so we’re going to clean it and pop a new olive on and re-tighten the fitting. So new olive, old fitting on. Re-tighten up. Sometimes you’ll be able to slacken off the fitting and just grab a pair of grips pop that round the olive and just wangle it off. But then sometimes you’re going to have to resort to this method to get the olive off. Every plumber out there has a different way of trying to seal compression fittings and I’ve just given you there ways of doing that. Follow us on facebook and twitter, And please subscribe! Remember there’s lots of different ways to do this. So test it out, give it a go and you may fix the leak! I hope you have enjoyed this video. The weather here is lovely!
