You already have a lot of cattle, but you have no other solution to open, to repair, in the case of the drops you do not say where they fall, if by the threads, or by some pore that with the use has been possible, I don't know how long It has that heater of use, think that heat creates lime and this is enemy # 1 of the metal with what causes it to rust and end up drilling, the best repair and for me the only valid one, change of heater, he says, if I can help you in something else, but that is not biting the wall, I am already 55 and itchy a lot in my life
Hello again, look, I've been watching and I have discovered at least that the problem is not the hot water tank. I have removed the mesh or hot water outlet pipe that connects with the pipe that leads directly to the tap and when opening the water comes out there and hot. Therefore the problem must be somewhere in the pipe. In my urbanization the water has a lot of lime and I don't know if the pipe in question is copper or not exactly. Assuming that this is the case and that there is a lime jam the problem has to be either at the entrance or at the exit to the tap. I don't know what else to look at. Maybe disassemble the tap?
Well look, do this test to see if you are leaking, with all the keys closed, you open the general stopcock and you look at the water meter if any wheel or needle moves, that is, if it tells you consumption, I don't know how it will be your water meter, if it moves you know you are leaking, you talked about a noise in the wall, so let's discard something doing this, so I understand what you say, when giving way to the water some indication will give us the water meter consumption, so you will have to see where the water is going.
