Greetings! A water heater of the same series as in the picture at the bottom of the article. There is a great desire to remove scale, because in the village there is specific water and I feel that the water heater will soon grunt for this reason. Duck, according to the documentation with the water heater that was going on, there is a magical entrance for a decalcifier which, judging by an incomprehensible picture, should still be somewhere somewhere. The search led to a hole plugged with a very soft plastic plug, but specifically fitted. I gave up my brains and realized that it couldn’t be so simple, because there is pressure inside this shaitan of the machine ... then a little more I started to think. If you cut off the supply of cold water, and try to put the anti-scale in the hose and then screw everything in place and cut in the cold water - in principle, the anti-scale should get in and all the rules, right? Any instructions on this? Thank you in advance.

I re-read the article several times and added to bookmarks, it will come in handy. This summer we bought a new water heater, and the old one must be put somewhere, but first of all, remove, and there is water. That was the problem. So and so I tried to pour water out of it, in the end it turned out, but not according to the algorithm presented in the article. As a result, after he was taken away and connected in another place, he stopped working. They could not identify the cause themselves, they had to call the master, pay him money for the old, but needed, water heater. After the repair I began to work, I think I’ll still serve a couple of years, and there you look and buy a new one.

Everyone needs such a good educational program on water heaters, thanks to the author. For the first time on our own, my father and I poured water, we can say, by touch. They read the instructions, but there is somehow little understood. So they were tormented. And since the water heater we plowed for about five years and have never been cleaned, when we removed it, we almost torn our bellies from gravity. It can be seen that it accumulated precipitation well :) It’s now leaking again, I think that definitely for discharge, the water needs to be drained again. Just do not understand about the drain tap on the pipe with cold water, what kind of tap? Is this a check valve which? And what to do with the valve, do not touch it? Thanks if you answer.
