Not be outside in winter

Basically, a clever construction of Gardena, which however has defects 2: The upper glands correspond in any way - as already mentioned here - the quality of Gardena. I also had to dispose of the part after 2 winters: residual water, rainwater and frost have 2 of 4 connections and made the housing leaking !! But it does not seem to be many alternatives, unless you Instructs its Klempter the making "right".
