I am a Hong Kong resident. Here is the 1st city to use salty water(sea water) for toilet flushing. Some of the tube and device are made of plastic for the anti- rusty reason. For here local plumber, they recommend 30 warp, and rolling it thin at the front(loosening direction) while thicker at the screwing end(tightest end) . For me, I will roll like that but only5-7 warps. I understand that they do not want to re- do, so 30 warps as their practice. (partly due to the thickness of tape). As I said, some tubes and devices are in plastic(nPVC) , be watch-out if warping too much for cracking the screwing. Also, if with a rubber pad, we can consider it as water tighted enough, try without tape. If dropping, then fill the tape a little bit 6 rolling warps around.

@@Jason-gj1pu I am not sure the bowl meaning. The toilet set area containing those dirt? Or the flushing water container? I guess should be the 1st one. Basically, the salt flushing water is not so clean due to sometimes repairing of the supply pipe(which is underground and have to dig). So the container would with earth precipitated. But the bowl, (if I guess right) inner of the toilet is clean after flushing. When I look into some info that, there is not many places using sea water for flushing. Hong Kong flushing water actually was flitered and de-salt to a certain level. Still, we have to avoid metal valve for flusing. So, have to be plastic valve/ tap supplying flushing water... and pvc pipe applied.

Lest you think I leave without a criticism, he did not mention that you should always use paste dope on gas lines, never Teflon. It may be different in your jurisdiction, but the gas company does not allow tape dope here in Pennsylvania. He did show several instances where you ought not dope at all. That upped his cred with me. I will say, a light coat of paste on some troublesome compression fittings has gotten me out the door and on to the next job.

I never use ptfe on compression fittings, but a bit of paste acts as a sealant AND lubricant. Stops that annoying squeal as you tighten the nut. Here in the uk we can use tape on gas fittings, but it has to be the thicker 'one wrap' which only goes round once. Trouble is that it's hard to tell if someone's used the wrong stuff, so hardly anyone used it, and I'm not sure if you can even get it anymore.

Nils, you hit on one of the most important points when using Teflon tape. When you have a rubber seal, don't use the tape. I made that mistake so many times years ago when I started out as a contractor. You run the risk of not getting the fitting tight enough to seal against the rubber seal. Great video, as always, and I can't wait for your future videos.

For high pressure helium fittings epoxy glue is applied to the threads as helium gas under pressure (~300 psi) will just about leak through anything except compression fittings or welded joints. To remove the fitting just heat the epoxy with a propane torch and it will allow you to undo the joint.

Totally true and something I had to learn with trial and error. If only this video was around 30 years ago 🤣

I'm in my 60's and have done plumbing all my life (not professionally). I've never used teflon and dope together. I've used them separately but it's never crossed my mind that you could use them together. If I used dope, it's always worked alone and the first try. Probably after teflon had failed.

Great video, with important information, as usual. As a relatively new homeowner, I love this channel. One method for applying PTFE tape that I learned years ago is to first tear off a small length of the tape long enough to wrap around the pipe several times. Twist it up long-ways, into a string, if that makes sense. Then wrap that string around the section of pipe you'll be taping, making sure it's seated down inside the threads of the pipe. Once that's in place, then apply the PTFE tape as normal like you explained. I learned that it gives a bit of an extra 'sureness' to the seal. I've always done it that way, since I learned it, but I'm not sure it's really necessary to do. What's your opinion? It seems to be cool to just use the tape properly without the added step.

Good to clear up misconceptions. I tend to use the thicker yellow Teflon tape

In my opinion people should learn to use plumbing flax and thread putty over teflon tape. It's a bit trickier but essentially follows the same principle but it's extremely reliable joint which you can even undo few rotations and it still wont leak. Works with water and pressurized air and despite what some people say in my experience it also holds glycol just fine.

Got it, thanks!

100% right on not applying teflon tape on first thread. Years ago we had a plumber install teflon tape extending past the threads damaging two chemical pumps.

I am very experienced because I wrapped hundreds of pipes. Stainless steel steam and water. I start the tape two threads from the end. Pipes are tapered. They seal as you tighten. I start with one wrap then as much as 3 or 4 at the back. I also use the edge of the plastic roll and roll it over the threads to push the tape into the threads. Germany uses strait pipes that don’t taper. They require string in the threads. I’ve done those too. The thing about liquids sealers is THEY HAVE TO DRY 24 Hours. Read the label! Each product has a different cure time. Stronger sealers have slow dry time.

All of this was good advice but one thing was wrong.. When wrapping the tape onto the pipe, the tape should start from BACK to FRONT of the threads in a clockwise motion., stopping just short of the end of the pipe.. This lets the tape overlap itself allowing the tape to flatten and seal itself as you tighten the joint... If you start at the front going back to the pipe, the overlaps can get caught on the fitting and get pushed off the remaining layers, possibly creating a leak situation..

Now that I’ve watched the PEX pipe video. I understand the basic concept. It’s kind of like what’s used in automotive coolant lines and other things. I’m not sure if it’s any better or easier than PVC. Maybe it depends on what you’re used to.

Thanks.

When Wrapping Plastic(PVC) Fittings DO NOT WRAP MORE THAN 3X or Your Fittings May Crack. Definitely do not wrap 6 to 7 times around.

I think the simplest rule of thumb is that Teflon tape is only for tapered pipe threads. It lubricates the threads and then fills the microscopic gaps and imperfections between the threads as they are wedged tightly against each other. I can't see the logic of ever using it on a straight thread as there is never a point where it is compressed into a tight seal.

He forgot one (and only) important fact...teflon tape does not seal. It merely helps reduce friction on pipe threads so that there is the tapered pipe threads are tight enough to seal on their own.

I checked the data sheets for a couple of different thread tapes for natural gas, propane etc. One white and one yellow. They were both made from PTFE.

Same tape I think, color just helps identify.

I was taught to always start the Teflon tape at the end of the thread that's furthest away from the opening. That way the overlaps don't face the fitting as it is screwed on.

The pipe dope/tape fills the void between crests and roots of the threads and lubricates the thread faces. It flows into place when compressed also filling common imperfections -- reduces need to over-tighten.

Do you have a video on blowing out irrigation for winter? Smallest compressor you can use? I've got an airmat blower, and another higher pressure one for dusting, probably not enough but maybe... Or just get a pro to do it?

Love the Ron Swanson art there 😅

Missed one important "mistake" -- use the CORRECT Teflon Tape for the purpose. The white is for basic water line work. I also use it on bolts (see below). They make "Yellow" tape for fuel (Gas, Oil, et cetera); they make "Green" for Oxygen Lines.

Another little tip... After you break your tape you can use the spool to press the tape into the threads to hold until ready for the fitting by placing spool edge on first thread and spinning around two-three threads to press the tape in. It will hold until needed.

Man, you are a genius😂

While threading on fittings is it advisable to reverse (or unthread) a little (say 20-45 degrees) a fitting sealed with teflon to fit and match the install??

I am from india Very good tips bro

Pink tape (and now, gray as well) is thicker and requires fewer wraps. I have frankly not used white skinny stuff for years.

Tape will also help align/clock the position of elbows and angled valves with more or less wraps.

I love the shirt! My wife accuses me of that in the past!

That's pretty dope!

That blue dope is the best thing ever.

Another great video. But I have to admit, a lot of this is common sense. I only use 3 wraps and I have never had a problem. I think anymore wraps is wasteful. Just recently I used this to fix a plastic hose coupling that had stripped and so I wrapped it and stopped the leaking. This saved me money. I would advise you to cut the tape instead of snapping it off because it's a pain to start the next wrap with a string of tape.

Green is to identify oxygen pipes and does not contain any petroleum products in its chemical makeup. Using it on pipes which are not oxygen lines can cause confusion and could lead to misidentifying the lines. Never do this. Yellow is for natural gas pipes .

You could be held legally responsible if someone gets hurt from mislabeling in wrong tape or wire colors.. Caution to this point for sure!

From my research and in talking to plumbers, everyone seems to have different opinions on this but one thing that makes a lot of sense to me is that if you're making connections that will be very difficult to access later on, use pipe dope or tape and dope. Underground and in -all, especially. For exposed and easy to access areas like under a sink, teflon tape might be sufficient. It seems like if you ask ten people about this you'll get ten answers but I wanted to bring awareness to the fact that you have options and sometimes tape by itself isn't the best solution.

I don't have a good way to do it. Usually, I tear off a short length and try to use two fingers to wrap the piece and then do it again with a second and maybe a third piece. Finally, I force the tape into the threads by rubbing my finger over the threads, to force the tape into the threads. There is no good way to start with a long piece because usually static cling makes the tail get folded over on itself. It's generally a frustrating mess.

Excellent 👌 Most make these mistakes. Common sense really.

Many don’t realize that pipe threads are tapered. (NPT=National Pipe Taper) Tightening threads is akin to driving in a wedge. Teflon is a lubricant as well as a sealer. It just seals what isn’t wedged solid.

Once upon a time I had a nipple going into the block of an old boiler that I could not get to seal. Old timer told me to use Teflon tape AND pipe dope. Worked so well that 20 years later I’m afraid not to use both when there is an old connection in the mix.

I would highlight the types of tape, because you have regular plumbing tape, but you also have gas/propane, coolants, or high temp tapes

What Roger says is true, and the condition of the part to be wrapped can be taken into account, as the number varies whether it is a new or used part, and the company’s instructions should not be followed in all circumstances, such as Nissan saying that you must change the transmission oil every 30 thousand, and not everyone adheres to that.

Teflon tape is also great minced in omelets for a perfect nonstick flip. Dont go overboard on pipe dope filling though.

In iron pipes with high pressure, I recommend to use (linen threads) then using Teflon tape with less than four laps....Sometimes Teflon tape alone is not enough especially with high pressures. If there is no (linen threads)!! Try to turn the Teflon tape to be like threads at first laps ,then continue as regular tape

my barb fitting was leaking even with 2 clamps on, so i just wrapped it with teflon tape. ez.

I learned a new trick just the other day not mentioned and that is the color of the tape matters. White is for water plumbing and yellow is for gas/propane.
