Dear, I have already seen that this issue has been discussed on other occasions, I have read and taken into account the recommendations but I have not found the problem yet. For a while, the pressure of hot water began to decrease in all the faucets of the house, the most affected is the shower, from which practically nothing comes out. The cold water comes out perfectly, with very good pressure throughout the house, including the shower. I have a Saiar multigas water heater of 120 Lt. lower connection (one year and a half has, maximum), attached photos. https://drive.google.com/open?id=1VxXFuwgcXohSimtoCpceGOaTAd0U4TF4 I disarmed the cold water inlet to the thermos and it goes perfectly from the net. When disarming the hot water inlet, I noticed that very little water comes out. The problem is then in the hot water tank? If so, what could be the problem? I would like to mention that in the cold water inlet to the thermos there is a stopcock, could this be the problem? (attached link of the connection photo) https://drive.google.com/open?id=1eJXe4izwdtMdGylaLm1do4Cct0WVaqRO Thank you in advance for all you can contribute. I do not understand almost anything about the subject, so I would appreciate every detail and possible clarification. Thank you! Regards!

Hi. In principle the installation would be fine check. While the blue handle stopcock could go elsewhere, it does not present problems for the operation but for the hot water cut. I should go to the exit of the wall and then the flexible one. The exit of the hot one, did you disassemble in the flexible, that is to say that it came directly from the thermos? Remove this flexible and insert a screwdriver or other long element through the outlet to see if there is no obstruction. The thermos on its own cannot be covered unless it has tartar at its base. This could prevent proper water leakage. Take the test and comment. Regards
