Guys, just fire!!!They chewed in an accessible language how to get the right drinking water in the kitchen and which filter manufacturers you need to pay attention to, they told me for the boller in the apartment and I also needed an air conditioner. Thanks to the guys, I closed all my problems. I also received a free consultation on how the engineering equipment should work with all the consequences.I am sincerely glad that you do not need to go to Minsk to get professionals.
