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.

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.

Many thanks. I would have never ever thought that you could use teflon tape on a compression fitting. But then boom! it worked like a charm.

Thanks man, fixed my leaky pipe in the bathroom and saved precious money on getting someone else to come do it.

[hollyhewitt]

Adding the tape completely worked. Thank you for the tip!

[danielgerrity]

Thanks for the tips! The hacksaw idea to remove the old ferrule worked perfectly and saved me an expensive call to a plumber.

A very useful guide for DIYers having their first dabble with plumbing. I've used all of these tips myself... Great reference video.

[petermcdougall]

Thanks for the video man. I was at my wits end trying to figure this out! The Teflon tape on the olive worked! Thanks again!

I was having a problem with a small trickle of water, tried this video and it solved my problem. Thanks!

[Aidandur]

Thanks mate. I used option 1....the PTFE. Worked a charm. . You're a gentleman 👍

[thomasmoran]

Love all your videos very informative easy to follow keep up the good work

[Ricky-eoym]

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.

Shit, I think this was the first time I ever liked and subscribed after watching only one vid.
That was useful!

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.

And if you can't get a hacksaw to it they make handy pullers for $10-$20 that will pull the olive off without damaging the pipe. Thanks for the video!

Thank you for the tape suggestion, worked perfect to fix a leaky joint under my faucet.

[roycraggs]

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.

I never knew that.... Thank's for the tip after years of bungling drippy joints! Better late than never however. Cheers mate
