Common mistakes made by DIYers when using pushfit plumbing. I use John Guest Speedfit here, but the same principles apply for other brands too.

Whenever I've used compression fittings (over 30 years) I have always had a leak. Always. I discovered these push fittings 20 years ago and decided to use them when fitting a new kitchen and bathroom. Jobs completed in no time at all and no leaks whatsoever all this time. Best thing ever for a non-plumber DIYer. Love your insights keep them coming and hope that your subscriber list improves dramatically.

@@sonacphotos I don't know what I've been doing wrong. As an example, a few years ago I had my boiler replaced together with a couple of radiators. I mentioned my leak problem to the plumber and he asked me to show him what I was doing (wrong.) He examined my work, said it was perfect, turned the water on and it leaked! However, I have followed the advice in this video and others online especially in regard to using PTFE tape incorrectly, experimented on an outside tap and woohoo, no leaks. It just goes to show you are never too old to learn.

One mistake some people make with compression fittings is using PTFE tape on the threads. That stops the nut from tightening fully and you get inadequate compression of the olive. Never use anything on the threads but you can put a smear of White Hawk or similar jointing compound round the olive.

@johnbower 5 ай бұрын

@@Phiyedough If the olive and seat are cleaned before tightening the joint will not leak, white hawk or similar jointing compound is for cowboys, try undoing and re-tightening a compression fitting that has been put together with jointing compound, after a while the compound will have gone hard and crusty, also some of the compound will find it's way inside the pipe and clog up any narrow passage like a rad valve etc. Cowboys won't be bothered about other things getting clogged because it will be another excuse to rip off the customer at a later date.

Hi, thank you for your video. I have used two pipe inserts and a coupler to fix a damaged pipe in my garden (for an outbuilding i have). After three days where everything worked fine, water came through again. After digging the pipe out again i noticed one of the inserts had come out of the pipe on one hand. Do you think it was because I put the insert in the wrong way (maybe not pushed totally in as the access to the pipe was very narrow and uncomfortable) or there might be some other reason? Do you have any advice to avoid such a thing in future, especially for peace of mind? I was thinking to add a layer of tape to give an extra layer of support, but that doesn't sound like a proper solution. Thanks in advance.

@TheDiligentDIYer1759 3 ай бұрын

It sounds like your pipe is underground, I don’t think these fittings are rated for use underground, ideally you would use the blue mdpe pipe and the pushfit fittings for those. I wouldn’t suggest taping it, I expect the fitting didn’t get a good seal when you put it on, the pipe needs to be clean and pushed all the way in to get a good seal on the O ring. Unfortunately you’ll need to dig a deeper hole and expose more of the pipe to sort it. You could install an access chamber so you can sort it if it happens again. Personally id dig in a new MDPE supply and get rid of any joins underground. Thanks for watching!

The seals are rated for 50 years if installed correctly, which does include the insert. That should out live most of us! Personally if I can use copper and solder, I will, but if not then pex is perfectly suitable. Thanks for watching!

It looks like the fittings shown can be dismantled but I'm using Hep2O which has no obvious method of dismantling. On one tee when I removed it one of the stainless steel inserts stayed in the fitting and I don't know how to remove it.

@TheDiligentDIYer1759 9 ай бұрын

Hep2o need a special tool to demount them, you can get them in screwfix or tool station very cheaply. I’m not sure if the fittings can be taken apart like a JG fitting, as i don’t use hep2o, but I would think if you get a pair of long nose pliers, you can pull the insert out of the fitting.

I realise this is an old video now, but I need some advice. I live in France and I employed a plumber to change the copper to plastic, as the copper is old and the joints are constantly failing. The plumber recommended multilayer pipe ie plastic with an aluminum liner and push fit fittings. He's left me with the job unfinished and as it seems impossible to find a reliable plumber around here, I'm considered finishing myself. Most of the videos Ive found are just plastic to copper, but I havent found anything for multilayer to copper. Do you know if I need any specific tools for this? As the pipe is aluminium lined, will I still need inserts?

@TheDiligentDIYer1759 Ай бұрын

I’m not sure why plastic would need an aluminium liner, seems odd. Standard pex is double walled anyway. Sorry i can’t help, best to speak to someone french! Thanks for watching!

Good video.. thanks..You say it isn't necessary to put an insert in a copper pipe when using a push fitting.. but does it actually make the seal less efficient by doing so?

@TheDiligentDIYer1759 10 ай бұрын

Thanks for watching! I imagine it wouldn’t be detrimental to the seal, however the inner diameter of copper pipe is larger than pex, so the inserts aren’t a tight fit in copper and would have an impact on flow, although likely negligible across your whole system.

Most of the plumbing in the house I moved into last year is JG push fit although the pipes under the kitchen sink and boiler are copper. Of the two, JG seems better to work with. With Hep 20 you have to twist the pipe into a fitting so awkward for a fixed in pipe where as with JG, you push the pipe in and and twist the collar on the fitting.

@craigs6892 Жыл бұрын

@@johnbeck5795 you do not have to twist the hep20 at all . The twist is to check only, it is a rumble feeling " insure joint tech " , very good . I prefer hep20 anyway , imo better grip and seal . Both very good and push easily, as said the hep20 is a twist to feel if required as this is great if your hands are right under a tight spot and cant see if the pipe went in far enough ( about 3/4" ). JG you need to see the pipe go in by the pipe markings , same as hep20 but at least hep20 has that secondary feel check.

They aren’t designed for copper, they are too small to be used inside the copper pipe. Copper has a larger internal diameter than the pex pipe. I don’t know why inserts for the copper don’t exist though, i guess the pipe is so rigid that it isn’t needed

@TeXiCiTy 5 ай бұрын

The only leaks I've seen with JG Pushfit are the combination of mounting under tension (inserting the pipe under an angle with force), not loosening the connector first and sharp edges on the pipe. This will damage the O-ring and if you're lucky it will leak immediately. Also, beware of sunlight. UV light can make the connection brittle over years when exposed. Any thoughts on insulating the push-fit fittings? They are quite bulky compared to compression fittings.

JG Speed Fit with modern unvented cylinders are "designed to fail" with one blaming the other. Spec JG speedfit: Cold (20°C): 12bar Hot (65°C): 6bar Modern (duplex steel) unvented, when airpocket not serviced: PRV: 8bar TPRV: 10bar (Manfacturers: there is no need for them to be this high!!! You should give customers options!). So, for hot water, the JG Speed Fit will fail when unvented is not serviced. Please don't say, "that's the customers fault for not servicing there cylinder". Unvented cylinders are designed to vent safely down the tundish when unserviced or when there is a problem . . . . they should not be releasing pressure/water through these JG Speed fit connectors.

@@TheDiligentDIYer1759I think you miss the point. Statistically, with 100 installations with your 7bar and 6bar relief valves and JG Speed Fit rated (their own spec!!!) at 6bar with 65°C water, more and more failures WILL occur. Factor in a scratched pipe degrading the effectivenes of the O-Rings or hotter water, that failure rate will increase especially when the unvented system is not serviced and the airpocket disappears and you have an overpressure situation. . . . . . like I said, a system desgined to fail.
