I was looking for a replacement for my two defective valves my water Lichtspiel column. I decided to buy, because I was taking no chances of a leaky connection, otherwise 8 liters of water would spread in the living room. That's me then quite a few Euros worth. And since the other articles not so good reviews bekammen and partly loud rating defective parts were delivered, I bought this valve. I am fully satisfied. I have two of these valves installed a. Directly behind the water column and in front of the compressor The air from the compressor is small but still great through and through and Lüftbläschen worry again for colors beautiful effects in the water column. Can the valves well continue Share.
