Really useful video thank you. I’ve just seen you have a new one 2 days ago so will watch that too. Love your tone of voice and I can tell there’s a wealth of knowledge so thanks for sharing!
thank you for your clear and candid explanation. I was confused as to whether to use ptfe tape or some pipe jointing compound to stop leaks in my radiator. now I know. Great to know about older techniques for stopping leaks like the hemp fiber.
Thanks Dereton. I always use Fernox jointing compound for compression fittings. I never find using PTFE tape never really effective on its own. An outside pipe, which is adjacent to my outside tape, was ‘weeping.’ I used PTFE tape, but it didn’t resolve the problem. However, after using jointing compound paste with PTFE tape, it did the trick.
@@dereton33 Thanks Al. I’m only a ‘jobbing’ plumber, who has limited knowledge and skills, hence I appreciate your extremely helpful on line tutorials.
i rarely use anything, unless like you say it is a used fitting that is undone and re used, i tend not to use compression though unless unavoidable, can't beat a good solder joint.
4:20 never used the hemp before, not sure about doing my new radiators, any other tips on fitting the valves to the radiator? not sure if i will do that myself or relent and get someone in to do it for me.
Not a fan of PTFE or Locktite. I still use jointing compound and hemp on all threaded joints and jointing compound on all compression fittings. Never lets me down. I do use PTFE to repair leaking packing glands though.
@@dereton33 It isn't about death, but bacterial infection.The safety data sheet (COSHH) states that hemp is not suitable for use with potable (drinking) water. It's worth viewers knowing of the risk and recommendations.
There seem to be two types in general, one that you can use for drinking water (non-toxic) and one you can use for non-drinking water (central heating systems?). I used some on water pipes this week for the first time to put some bib taps on. I used ptfe (wound the right way for the thread so it won't unravel when you screw it on), and then the jointing compound. The first try weeped a little so I used more ptfe near the base of the tap thread and the jointing compound, then left it a few hours with the water off, even applying some gentle/ambient heat to help it harden up a little and it was ok in the end on a full pressure cold tap. This is what I used - www.toolstation.com/fernox-water-hawk-jointing-compound/p14953
Quick question, you say to use PTFE tape on all threads but on your how to remove a radiator for decorating there wasn't any PTFE tape shown when disconnecting the pipes from the radiator or when reconnecting the radiator. If there isn't any PTFE tape on the valve thread when I disconnect the radiator, should I put some on when I reconnect it?
My pet hate is when people wrap p.t.f.e around compression joint threads. Perfectly fine to wrap it on the olive itself as that seals the integrity of the joint. Thanks for sharing Al 👍. Quick question I generally use white tallow for pulling cables through conduit. Are there any applications it can be used for in plumbing?
It used to be used in wiping lead joints, it is good though for pasting string and using for packing material in leaking stopcock gland and rad glands.
@@dereton33 Ok so it's similar in property to liquid p.t.f.e or silicone grease. I'd guess more like p.t.f.e myself. I'm going to give it a whirl on some joints. I have a massive bucket of the stuff 😊, Thanks Al 😉
Correct me if I'm wrong but it seems to me with both the tape and hemp you've wound it in the wrong direction? So it will tend to unwind when you tighten the nut??
@@dereton33 I am so sorry, I made a dreadful mistake. In both cases you were in fact winding the tape and hemp clockwise around the thread ie in the SAME direction the nut is turned to tighten up the fitting. I've watched many of your videos and always found them very well presented and very well explained. My apologies again.
When I install radiators I usually do 23 to 25 wraps. If I do less, then the tail doesn't get tight by the time my spanner starts touching the rad. I have recently bought some loctite 577 to test out. I have had some success with loctite 55 as well. One day when I have the time I will probably do some sort of test to see what happens when I only do 6 or 7 wraps like some of the rad valve manufacturers say.
There's something heartening about listening to an old boy who just knows from experience what he's talking about
Old....what.
@@dereton33 I said boy...I threw you , that, bone
One of the best UA-cam videos I have watched for a long time. I liked everything about it
Thanks Madeingreatbritain.
We need more of these valuable lessons from a guy who clearly knows his way around rather than the usual 2 week plumber course guys elsewhere
Thanks Bill.

Thanks Al, helped me fix an old BSP radiator coupler that was dripping.
No problem Neil.
Great video, I often use compression fittings at work, but until now, I have never seen the ptfe trick, thanks for posting!
No problem 👍

That`s true.
Keep them coming,.thanks for the time and knowledge 💯
Will do!
thankyou Dereton. I am about to fix a sink so will use your tips.
No problem 😊
Excellently presented and explained thank you
You are welcome!
Excellent bit of advice for us notices
Happy to help

Some rad valves come with the required amount of PTFE tape already wound on. Otherwise it is hemp or PTFE tape.
Not a fan of PTFE or Locktite. I still use jointing compound and hemp on all threaded joints and jointing compound on all compression fittings. Never lets me down. I do use PTFE to repair leaking packing glands though.
Thanks
What about on plastic drainage pipe under the handbasin. Tiny leak. I replaced the trap underneath 😢 still a tiny leak
Best to use solvent weld.
Great video, thank you.
You are welcome!
Really good video. Thank you
You are welcome!
Always put compound or ptfe on old or new fittings eliminate the risk of leaking auld yin
IT`s a case of your choice. I always use compound old or new joints.
Lots seems to use a liquid thread sealant these days, like a locktite, on rad tails. What's your opinion on that Al?
Never liked it and still dont.
Hemp and hawk white on rad tails is only job
Fantastic thank you very much 🙏👍
No problem.
Thanks for helpful video.
Most welcome!
I think you should wind ptfe tape in the same direction as the nut turns
Yes but I was just going through the different things you can use.
I heard that hemp isn't suitable for *drinking water supply pipe* as it can support bacteria growth, but ok obviously on central heating.
Been using hemp on pipework for over 50 years, no one is dead yet.
@@dereton33 It isn't about death, but bacterial infection.The safety data sheet (COSHH) states that hemp is not suitable for use with potable (drinking) water. It's worth viewers knowing of the risk and recommendations.
@@dereton33 please come and do some plumbing at my house then, as I am already 61 and would like to live another 50 years 🤣
How much nutrients that little piece of hemp gonna provide to bacteria? Bugger all.
@@thelogician1934 Whatever bruv
This is a very useful video - thank you. Which compound paste do you recommend lots of brands and variety?
Always boss white for me.

Never mind. Just saw from your "how to fix a leak" that there's an olive in there.

Can you use PTFE & jointing compound together for radiator valves?
No one or the other.
@@dereton33 thank you for the prompt reply.
@ dereton what can i use on gas pipe that connect to the back of a cooker.
A bayonet fitting then a black flexi hose to the cooker. Just to let you know, you should be registered Gas safe to touch anything to do with gas.
@dereton33 yeah I have all that will I need ptf ( yellow for gas to seal pipe to cooker?
What about lock tite on rads
No. Tons of leaks reported where people have used that stuff.
how can i soften up my boss white which has hardened in the tub??? can i mix anything in to soften it up again???
No once it is dried up that`s it.
@@dereton33 thats a shame as the tub is still half full
How many turns of ptfe tape are sufficient for rad Tails , Al👍
6
On thread connection I normally rap PTFE tape around 20 times. By looking at this video I been putting on way to much 😂
You can usually tell by the amount spilling out from the thread.
When I install radiators I usually do 23 to 25 wraps. If I do less, then the tail doesn't get tight by the time my spanner starts touching the rad.
I have recently bought some loctite 577 to test out. I have had some success with loctite 55 as well.
One day when I have the time I will probably do some sort of test to see what happens when I only do 6 or 7 wraps like some of the rad valve manufacturers say.
Wouldn’t you wind that ptfe the other way round. ?
Yes I was just showing that it has to go round, but it is the other way.
Would this apply to compression onto JG pex too?
Yes.
Thanks 👍🏻
No problem 👍
Swinging 60's and smoking hemp ✌️✌️✌️
A great time was had by all, ha ha.
@@dereton33 rmods and rockers birds with big knockers 😍😍😍
Which paste do you tend to use?
Boss White.
If I have a pipe against the wall I use the mini strips and put it behind the pipe and clean it that way😘
Great idea.
I always use hemp on threaded joints. Never fails. PTFE failed for me once so my go to is the hemp stuff. Always works
I use it with boss white, never fails.
I only use ptfe paste no tape at all
Works fine.
I bought hemp at screwshit ✔️✔️ the other hemp I bought i smoked every bit 🤣🤣🤣
Bwahahaha 😅😂🤣
Keep em coming Paul. ha ha.
@@dereton33 you do the video presentation i'll stick to the jokes 😂😂😂😂📹
Never EVER use an old piece of pipe !!
Don`t talk rubbish. I have used many an old bit when stuck. Copper pipe last a long long time.
