  • A UA-cam viewer asked me to shoot a video on "Pipe Thread Sealant". At first, I thought it wouldn't be such a popular topic but after checking out some other You-Tube Videos I digress!
    So in this video, I give you my thoughts and methods on the subject and in addition, feature some of the products I use in my everyday plumbing practice.
    I'll leave links for the featured products below and as always you can reach me at info@bobsplumbingvideos.com. if you have any questions. Best Regards, Bob.

    Disagree with covering the first thread with Teflon tape. Keep the first thread clean for an easy start. I agree with you and also do not run the tape all the way up the thread, it's just a waste of tape as those threads will never enter the joint. The other reason for not cover the first thread is any tape hanging over the first thread and end of the pipe WILL break loose and enter the piping system. In some cases this might not be a problem but in others you never know where it might travel to. Solenoid valves in dishwashers or ice makers are two examples where you don't want fragments of tape to be.

    Excellent video, very informative. When I built my house about 30 years ago I hired a plumber friend to do the plumbing and I worked along with him. I had some experience sweating copper and working with PVC but by the time the house was finished I had experience with gas line installation, putting in a boiler, running a threading machine, codes, you name it. I think I could have become a plumbers apprentice. One thing he taught me that has stuck through the years is when allowed (not on gas pipe) to use Teflon tape and then pipe dope over it. He said doing this will just about guarantee you'll never have a leak and I never have so it was interesting to see that you do the same thing. The only time I ever had problems doing this was when I had to replace a leaking expansion tank on my boiler. The expansion tank is threaded into an air scoop which is made from thick cast iron. Teflon is a great lubricant and it allowed me to over tighten the expansion tank pretty easily and put a hair line crack in the scoop. I was told later by another plumber that he never uses Teflon tape on cast iron for just this reason, a lesson he learned the hard way himself.

  • @americusdeville865

    Definitely learned from you about the pipe thread sealants. I am replacing a PRV. I put Teflon tape on the threads. The PRV is a brass fitting. The locknuts are brass from existing hardware on collar/tailpiece assembly. The bottom locknut seals. The top locknut is not completely flush, so the locknut does not bottom out correctly. Never used to paste before, but I am going to try it. If it works per a man of your experience, this is going to be a fun installation. This problem had me stumped. I lacked insight on the solution. It's a residential pressure reducing valve so I will set the psi at 60--65, but first I got to make sure the connections are water tight seal. Looking forward to plumbing.

      Use it on any threaded seal connection. Drain pvc, drain brass, drain copper, iron natrural gas, etc. If its threaded...use some pipe thread sealant. Its not for sealing, its for anti-galling of threaded connections. Remember that. But that means sometimes you need it to get something tight enough to not leak. And without it you may have threads galling and not allowing full seating of your connection.

    I learned with lamp wick and pro dope in 1998. I had an old school plumbing instructor. Still my preferred method. I've used mega lock here and there. With the tape I learned to put the dope on first then the tape over it. Real Touff I mainly used for fire sprinkler systems. Blue block makes a mess, it's like paint and gets everywhere. I didn't do much gas piping, but I used it exclusively for oil, from the tank piping, oil filter, firomattic valves, up to the burner.

    @jerrydelany926 4 роки тому +3

    Very good video. One comment though. I am a retired instrument technician from a nuclear power plant. We stopped using teflon tape in the plant due to technicians installing teflon tape to the very end of the threads (the narrow end). For a while we could use pipe dope only. Because the threads are tapered, the first and / or second thread do very little in the sealing process. What we saw occurring was pieces of the teflon from the narrow end would become loose and go into the system (water, steam, whatever system it was on) and clog something down the line. We call it foreign material in a nuke. Not good for the plant.
    I noticed in your video you like to go to the very end and even some of the tape was over the end of the pipe somewhat. That was something we had to be very careful not to do and I follow the same practice when I do any plumbing work.
    Another note. I was watching your video because I am installing a water system in my house. It uses plastic fittings (male and female) and I am using brass fittings to join the house to the new water system. I encountered some leaking problems and was wondering if you have any thoughts on sealing those kind of unions. Thanks, Jerry

    • @BobsPlumbingVideos
      @BobsPlumbingVideos  4 роки тому +1

      On brass to plastic connections as a rule on waste lines (low or no pressure), I'll use a good quality Teflon and the Mega Lock joint compound together. On pressurized water line's I'llsubstitute the Blue Block instead Mega Lock. In extreme conditions, I use the spool lampwick and Blue Block.

    Love the Megalock, discovered it by accident at Home Depot, just using it for water fittings around the house. Back in the late 60's/early 70's I worked for a gas utility, they exclusively used the old yellow Rectorseal. No teflon in it in those days. I always felt it just lubricated the joints, with high pressure mains and gas at 75 or so PSI, how could compound hold back the gas, it's really the compression of the pipe and fitting. We always called it pipe dope, never heard anyone call it compound.

    I like real tuff over Megalock but like you said it is difficult to clean for sure, almost like a white tar if that makes any sense. I’m probably using way to much.

    I think I am over tightening, as it is a bear trying to take apart years later. What is best to use to make taking apart easier? I have always stuck to straight teflon, but if something makes taking apart easy, I would change.
    I am needing to reduce a 1" plastic, male, pipe threaded, fitting on a water softener, to a 3/4" male pipe thread. It came with a gator bite to 3/4" pvc or smooth copper pipe, but I have converted system to threaded at other ends all already for simplicity. It is plastic, si Was trying to stay plastic on plastic to protect water softener fittings. The in and out from wall has 3/4" male threads for using hoses. I would use the shark bite method, if I could find a short, 3/4", smooth to threaded copper pipe.
    My in and out from wall are opposite the in and out on the water softener, requiring me to cross the pipes also.

    Great video, thanks for sharing! But still have a question...
    I have a shower head arm that is a little loose when oriented in the correct direction. If I try to make one more revolution the arm gets so tight it only makes it 3/4 of the way around.
    Wondering what I can do to ensure that there is no leak since this is a remodel and there is no way to see if there is a slight drip inside the wall

    • @BobsPlumbingVideos
      @BobsPlumbingVideos  3 роки тому +4

      In a situation like that, I'll remove the arm and double down on the amount of Teflon. Instead of 5 or 6 times around I'll go 10 or 12 times around. It will usually make up the difference and you won't have to make that final rotation.

    With threaded brass fittings, leave ~2.5 threads showing on the male connection as a general guide to avoid over-tightening the softer brass. Brass threads can warp, crush or distort if over-tightened.

      If you don't make the brass scream, it's not tight enough.

    Awesome video, Bob. Thanks so much.

    • @BobsPlumbingVideos

      When I screw schd 40 pvc on or into metal pipe I generally use teflon tape followed by Blue Block or Grip. Either or will work.

      @@BobsPlumbingVideos and only to prevent abrassion on the plastic part and prevent sticking, so not as much as metal-to-metal, right?
      BTW, one can really see you know your stuff. On the other hand I like the looks of neatly wound teflon tape sticking out - it looks clean and done to me when checking later (but only on ugly plastic or metal hidden joints, not the fancy visible shiny pipes).

      Bob great video and thank you. I was a pipefitter for the gas company here in St Louis 35 years. As you can imagine I've been through a variety of different pipe compounds (pipe dope) in my day . I ended up finding a correlation between the quality of pipe dope and my wife doing laundry. If my wife could get the pipe dope stains out of my work pants ,I found it was not a very good pipe dope but on the other hand if she could not get the stain out, I found those Brands & types to be the best. I found it surprising that the gas industry in New York does not allow yellow Teflon tape in certain applications. I find it absolutely necessary to use yellow Teflon tape and pipe dope once you get into the pipe sizes of 1 1/2" & larger with deep threads, such as Chicago service head adapters.

    Thanks a lot & excellent video. I'm making a bean bag aka tree climber throw bag launcher with black steel. Don't trust PVC at 330psi, or even 100psi which will be about max. Should be a safer. Would tephlon tape be enough for 100 or so psi for say a 1hr or so? Or Blue block also

    • @BobsPlumbingVideos
      @BobsPlumbingVideos  5 років тому +1

    Blue block with teflon tape works in both new and old pipes because the new ones come with all kind of impurities also, you don't want to take any risk. Of course for the gas pipes only blue block on the male thread.

Cleaned up the treads pretty good, use Teflon tape, Still have a Very Slow Drip! would You recommend the Blue pipe sealant You use to fill the Tiny imperfection in the Pipe? Again HELP! LOL

  • @Techmatt167Official
    @Techmatt167Official 6 років тому

    I have a brand new shut off valve threaded onto a nipple coming from the wall and I did about 2-3 turns with Teflon only and it’s leaking. Should I do more turns with Teflon AND add some thread sealant? I’ve been reading many articles on when to use one or the other or both and I cannot make up my mind. Maybe I’ll just end up experimenting with what works best.

    • @BobsPlumbingVideos
      @BobsPlumbingVideos  6 років тому

      If it's older pipe I would a combination of Teflon and pipe joint compound. A high-density Teflon (amzn.to/2v0s3pk) would be the best, as far as how many turns I've gone as few as 5 or 6 and as high as 9 or 10. Depends on the condition of the pipe.
