How much thread tape for pipe fitting?
Have continued searching on YT. The amount (turns) of tape seems sparse in many clips. Lin seems clearer that it should go up to the thread, not over. This clip seems reasonable!? https://www.youtube.com/watch?v=bFXgwO9qszY

My experience with linen is that it never leaks. The times I have made tape seals, I usually have to redo it 2-3 times, either everything gets pushed into a lump behind the thread, or it doesn't seal properly.
With linen, I have encountered a few times, maybe 3 out of 200 connections. When the linen gets pushed out when threading it together. But otherwise, it always seals properly. Linen has the advantage that it swells with water, so it is somewhat self-sealing.

Also use flax every time, even for small dimensions. It's the fastest and ensures a tight fit every time. Scratch the threads, pull the flax so there are no tangles, apply from the end of the pipe and follow the thread. Finish by applying paste so it saturates the flax well by rubbing it in with your fingers. Then just screw it together.
An additional advantage of flax is that you can back off a little without it leaking. That's impossible with tape.

The films in #17 and #18 are far from well-executed.
- Why lock the first turn across? It adds nothing but bulkiness. Unnecessary.
- Don't see any "ritsar" in the threads. A good insurance against slipping lin.
- Do not finish the wrapping at the tip of the pipe.
- Often, the wrapping is easier if you skip paste in the bottom of the threads. But there are different schools of thought here.
- Slightly too little lin. Should be a little, little more.

Yes, that's true. I expressed myself unclearly, it's not "impossible" but for the average person who buys a thread tape in the nearest bush, they will get a tape that leaks if you reverse.MathiasS said:

-Simpler at the beginning to hold the line in place, so it doesn't spin.M MagHam said:The films in #17 and #18 are far from well executed.

- See no risers in the threads. A good insurance against slipping line.
- Do not finish the wrapping at the very front of the pipe tip.
- Often, wrapping is easier if you skip paste in the thread base. But there are different schools of thought here.

-Only needed on brass.
-Yes! Then the line is locked in place when the fitting is threaded on.
-Agree.
-Preferably quite a bit more.
In summary: -With a little more line, the instruction is correct.
