A few days ago we had a problem with boiler and hot water (see post here). Just solved the problem and winter weather created the new one.
Look at the first photo: the pipe from kitchen sink is bent. Water stays in the bending and freezes up 🙁

Class 5+ network cable is always helpful. I made connection to the pipe above and hopefully I have resolved the problem forever. Hopefully because the pipe still stays in horizontal position instead gets some small angle…

Another problem is with pipe from shower tray – it had been friezed up as well, probably because of horizontal emplacement instead of little angle…

We are really missing the summer time 🙂
