    Hello,
    I connect the dishwasher, I have to divide the cold water connection, which until now had only a tap from the faucet. It looks like:
    Unable to Unscrew Metal Valve from Elbow on Cold Water Connection for Dishwasher Installation
    The problem is that for China I can not unscrew this metal valve from this elbow, I grab the plastic round with a frog, the other for the valve and I turn - NOTHING. Left, right, alone, in two, and nothing. I'm afraid I'm about to tear off the entire pipe. Do you have any advice? It seems to me that this non-woven fabric has swelled so much that it made some groats there.

    (of course, the photo shows the condition before turning off the water and unscrewing this hose from the battery)

    Plastic pipes, block the pipe with one key, turn the valve with the other key, if it does not blow, it will break and you will have to replace a piece of plastic pipe. For this you need a heater with the appropriate tips

    Well, thanks - at least if I break something, I will not panic if it can be fixed somehow without hammering :) but the trash just out of this world.

    There is another way, screw the tee to the valve and you will have the problem solved.

    In the sense of screwing a tee into the place where this metal tube comes out? It seems to me that the diameter there is too small for it to work effectively, not to mention the fact that I have not seen tees with such a diameter of one of the inlets.

    "Uncle Andrzej" is about to come, a man who can unscrew seized screws from the collectors with his bare hand ;) If he can't, it's just dynamite.

    It will be a 3/8 inch tee (ten), plus two nipples. There may be a problem with the sealing of the tee-valve connection. In case of dripping, unscrew and increase the amount of sealing (I recommend hemp / hemp). Select the nipples with an even surface "from the front", in case of unevenness, the surface of the future clamp should be leveled with the hose seal.

    Perhaps a measure for loosening seized parts would help?

    There is one or two companies for sure.

    Description of one of them:
    Loctite 8040 Freeze & Release immediately cools seized and corroded parts (bolts, nuts, studs) to -43 degrees Celsius. C. As a result of the unique thermal shock, many microcracks are formed in the corroded layer, which allows the lubricating components of the product, thanks to their capillary properties, to penetrate deeply. The fasteners can be easily removed after a reaction time of 1-2 minutes.

    I have not tried this method. Perhaps it is effective. If it turned out to be so, write :)

    greetings

    Archaeological topic, but I will share with posterity, because I have just fought a similar situation.

    Faucet on the outside. Ni chu..chu did not walk with wrenches or a hammer and chisel - I tried to hit the nut. Not a small burner - styrofoam and acrylic all around, the plastic pipe started to melt.

    Threaded bathroom descaler.

    After about 10 minutes, he set off with the key (!). It's very hard, but I unscrewed it.
    Internal pipe thread intact. The problem was a bit of muck with tow and stone on the very edge. The new tap came in smooth and works.
