Good. I have been observing for a while that the faucet, single lever, from the sink of my kitchen leaks, but it does not do it by the pipe, it does it by the part of the command. The funny thing is that it only drips when it is in the cold water position, but not when it is in the hot water. I have not paid much importance since we rarely have the thermos on and we can work with hot water without opening the heater so it comes out cold. However, now it has also started to drip with hot water, although it is not something of importance and the loss is less than with the cold position (which is not to alter itself). I've started to review videos and tutorials. At the beginning I tried to disassemble the tap completely but I have the screw and the nut that presses it completely rusty, forming a single block. With my tools I can not release it (or access is easy for a wrench, the sinks of the sink bother). On the other hand, I have seen that these faucets can be fixed by changing or checking the rubber of the cartridge and I have pulled this option. I have removed the screw cover that I have to release. Allen's screw was quite hard and sometimes I danced the key until I took another new and harder one, also 2.5 ". With some force I managed to remove the screw, but with such bad luck that it stayed inside me of the remote, loose. I did not find it problematic, it was only to remove the remote to access the cartridge but it does not come out, it seems stuck. I tried, giving some blows, see if it is released but I have not achieved without leaving the tap made a Christ. Something will have moved because now the water has lost some pressure, even if it opens it fully. It no longer reaches its maximum opening and does NOT come out with force and, to top it off, in the option of hot water no longer comes out of water, just a slight drip greater than closed. Anyway, I show you some photos. I tried to pour some vinegar inside if the lime had left it as a block but I have not achieved anything, honestly. In short, my faucet is rusty enough under the sink that doesn't let me unscrew it, and hard enough on the knob to be able to take it out without spoiling it at all. Any ideas ???, I have missed some more screw to remove and why not come out ?? (Or get the remote and check the cartridge would come with the solution).

Hi Kchoprro. For what you manifest and show in the photograph the problem of the lower part derives from the dripping of the upper part. The baler that goes between the sink and the key is no longer doing its job, filters and therefore the rust. If the screw stayed inside the key or the control, it is stopping or jamming the control when opening it. Hit the key with soft strokes to see if it changes position and gives you a chance to open and close. Usually the handle of the key comes out with a little force towards your side. Some that have more time are oxidized and it is a little more difficult, if you have any type of rust remover or SQ place it. and try again. Perhaps with much more strength. or knocking the knob a little on the sides to see if it loosen the rust a bit. and once you manage to open or disassemble the key, safely changing the gaskets will solve your problem. Some depending on the brand must be changed because they do not carry rubber but a kind of ceramic disc that when worn out has no arrangement. I hope I have placed some light on your doubt. Comment

Hi. Do not hit anything since you will break the cartridge and it costs its good weights. In the opening handle you will see that there is a hole. Over there a prisoner with an Allen head is loosened. If you loosen it, the handle will come out and you will see if it is only a matter of adjusting the nut of the cartridge or it is necessary to change its ring or gasket. Regards

In my case, the solution was to change the cartridge for a new one. It's funny, the old man didn't seem in bad shape but I didn't want to take a chance. I found a cartridge according to a plumbing shop (I didn't find it in large hardware stores). The process was as follows (although there are several videos on YouTube of this process): 1. Close the water stopcock. Remove the circular cover that closes the access hole to the Allen screw (normally this cover has blue and red colors painted for hot and cold water, taking advantage of the need to cover the hole). 2. Use an Allen wrench, insert it through the hole to access the Allen screw that secures the cartridge (it presses on the pivot that allows the control to tilt). The screw is loosened, it does not take much, we can run the risk of loosening the screw completely and it stays inside us, 4-5 turns of the screw should be enough to let loose the control. 3. Pull the control towards us, in this case, holding the tap to pry and not to come too. The control comes out under pressure, it has no more nuts than the Allen screw that only stops it. 4. In view of the mechanism, it is necessary to unscrew the large nut that fixes the pressure cartridge avoiding water leaks, but first you have to remove the bezel to be able to insert a wrench (not less than 30 "). The bezel It should be easily unscrewed simply by hand. 5. Removed the bezel, unscrew the thread and we will have access to the cartridge that we can extract only by pulling the pivot towards us (if it is stuck, we must use pliers that hold firmly). 6. With the cartridge removed, the new one is inserted and the steps are reversed.
