Even after opening the two valves and run empty it is torn in light frost; the ball check valves are thereby leaking and dripping out everywhere. In addition, the small levers appear are difficult to touch and turn.
Now I've had enough of the plastic objects we build me brass parts itself a distributor with two Kugelhahnausläufen. Since the lever are a good size and the total is not more expensive than the finished solution from plastic.
Too bad, otherwise many things from Gardena are really good, but the distributors are botch.
