Water in the boiler rust

So that the water does not rust. We built a bath on the plot on our own, the bath turned out very good - 3 x 3.5 m. Ordered the oven "Topi and washing", but the boiler was not lucky - water rust. What can be done in this case - tell me

"Itself will not pass" - as your neighbors say. Diagnosis at a distance, "without seeing a patient," to do is not easy, however, we assume two ways to correct the situation. Judging by the photo of your oven, which I found on the Internet, the water tank is made of stainless steel. And water supply pipes, most likely steel, and possibly copper. In the case of direct physical contact of the listed metals (in the direction of water movement, copper - steel) occurs electrochemical corrosion, which causes partial dissolution. To fundamentally exclude such a destructive interaction of metals, replace metal pipes on polypropylene. In addition, again, judging by the photo, the design of the tank is such that it is easy to clean from rust from the inside, using a metal brush for this. If it succeeds, then, well drying them, cover the stripped places of waterproof paint. For this, authemal will fit well.
