    Hello,
    I have a problem because I flood my neighbor, it is leaking hot water from the bathtub faucet in the wall behind the bathtub.
    I carved a tile under the bathtub to see what is going on there and it is clearly visible when I turn off the valve, hot water stops flowing down the pipe. I called the plumber, he replaced the cam and the extension on the battery, the pipe was dry for 3 days, but the problem returned again. I am devastated. Do you have any idea what it might be? Can it be repaired without pricking the tiles and, what's worse, disassembling the entire bathtub?
    In the attached photo before the renovation, I marked where I have a visible stream of dripping water from the top of the battery. There is also a photo after renovation, where you can see that to get to this pipe I would have to do a lot of demolition.

    I suspect that one of the threads has become unsealed again.
    Twist and fix the plumber.
    When unscrewing, you should see and "feel" whether the threads were tight.

    I called the plumber again, he already scared me that the tiles may have to be broken down.
    Let it, or is it better to unscrew it and screw it up again?
    Could the reason for a re-leakage was that I was cleaning that pipe down there from limescale that had deposited on it?
    It might not have been some strong movements, but it was still moving.

    Very likely.
    The plumber used Teflon tape for the threads?

    From what I saw, he was winding tow or hemp. Teflon tape is better for this?

    I would do it again, since 3 days was fine. There is no connector in the place where you showed it, so it is leaking from the top next to the battery. Maybe when he mentioned these connectors, the tow fell off and they do not hold. Don't forget to put a sealing paste on the tow at your plumbing stores.

    That's why I ask what the plumber used.
    I also have a suspicion that it slipped off and "barely held".
    If a specialist will unscrew the fittings, take a look at their threads.
    Is the seal left or the bare thread "shines".
    The latter option EXCLUDES a repair in the form of a warranty.
    He fucked it up the first time.

    The situation got even stranger because today it doesn't run down the pipe again, which made it even more complicated.
    On Friday, the extension and the cam were replaced. For three days it did not leak, and on Monday evening it started to leak again, so as not to flood the neighbors, I turned off the hot water for the night. On Tuesday morning, to check, I unscrewed it and after a while water began to leak again, I turned the valve again. On the same day (Tuesday) after work approx. At 4:00 p.m. I unscrewed the valves again and, to my surprise, the water does not leak.
    Now I don't know anything at all. What could be the reason why it leaks and not?
    I will observe the situation, but it is impossible to live like this. Advice something.

    As I wrote.
    Unscrew and reseal threads.
    Your experiments are a coincidence.
    Perhaps the system pressure is fluctuating.
    Maybe the heat of the water expands the metal and seals / unseals.

    You were right yesterday late in the evening it started to trickle again - I turned the water off, and this morning I turned it on and it's not leaking.
    So probably this changing pressure has an influence, in the evening and at night, when no one is using water, the pressure in the installation rises and one of the connections is released. Today I am calling the plumber for a correction, because unfortunately I cannot and do not have the appropriate tools.

    I just keep wondering if just unscrewing and sealing the extension and the cam will help? It was done by a plumber with 20 years of experience and I don't want to believe that he would install it incorrectly. I am afraid that this elbow in the wall is letting it go somewhere, and this, unfortunately, is associated with breaking the tiles and hammering in the wall.

    Anyone can have a mishap.
    Or maybe the extension and / or the cam has a flaw (microcrack etc).

    However, you may find that you have damaged the pipe itself when cleaning / forging.
    We're worried about the threads and it's leaking from the pipe
    Are you 100% sure that it is dripping from the top?

    I was cleaning it gently with a sponge, so certainly not from cleaning. Water obviously flows from above, because as much as I can see from the bottom of the bathtub, the wall above gets wet, but from which point it is unfortunately hard to tell without forging. I pictured it in the photo.

    I wish you luck that these were leaky threads after all ;-)
    You will see right after unscrewing if the seal was in place.
    Look at these connectors if they are not damaged.

    It is on the bank that the threads will connect. In exactly the same case, I chained the entire bathroom ...
    It turned out that someone who wound the tow did not cut the threads and the tow ... "rolled up". This caused a temporary seal that came loose over time.

    You do not need to forge anything here, you need to carefully look at the place where the valve or the pipe extension is screwed in.

    Pakuła, Teflon, one czort. It is important that it is professionally wound.
    And as it is now, it will turn out after the removal and whether we were right.

    The plumber insists that he turned everything well, but it is staggering, however, that it was 3 days from replacing the extension and the cam.
    Today it comes with the intention of forging tiles, now I do not know whether to let him do it, or to have the threads unscrewed and sealed again.

    The plumber claims that if it was leaking from the cam, you could see the leak more at the battery than in the wall. But surely when it leaks from the connection of the extension with the elbow, water may run down the pipe in the wall.

    Better to wrap the threads with tow or Teflon tape?

    It's nice that you know it and he doesn't!
    Let him dial it and show it to you!
    I am writing about it for the 10th time!
    A friend too!

    Forging is probably a last resort and costs.

    Opinions vary. I do both.
    It is important that it is well made.

    Re-sealing the extension and cam to nothing. After cutting the tile, I saw such a view. What's worse, it stopped leaking at this point, so I can't see where the leak is.

    Ooops. Pity...
    And we have more threads :-(
    "Bigger" forging is getting ready to get it going.
    May it not drip from the weld (tubes with an adapter).

    I had transitions with the cam and it's quite new because it was screwed in a month earlier with a new battery. After a month, a minimal leakage started, so I figured I had a bad tuck. Five times I unscrewed, tucked and still wet on one side and ok on the other. Only replacing the cam with the old one helped.

    Water was leaking from the connection between the pipe and the plastic coupler. It turned out that the previous owner of the apartment had to repair it earlier, he did not weld the connection but simply put it on with a gasket. Now it has been put together properly (welded) and I hope that the end of my troubles. Below is a photo after repair.

Topic summary

The discussion revolves around a persistent leak from a bathtub faucet, which has caused flooding to a neighbor's apartment. The user initially had a plumber replace the cam and extension, which temporarily resolved the issue for three days before the leak returned. Various suggestions were made regarding the potential causes, including improperly sealed threads, the use of tow or hemp instead of Teflon tape, and fluctuating water pressure affecting the seals. The user expressed concern about the need for extensive demolition to locate the source of the leak, but others advised that careful inspection of the fittings and threads might suffice. Ultimately, the user discovered that the leak was from a connection between a pipe and a plastic coupler, which had been improperly repaired by a previous owner. The connection was subsequently welded correctly, leading to hopes of a permanent fix.
