The stop is not at the point

The gun is metal, nice, neat construction seems the apple turns and clicks clearly, no complaints ... to relax gun after use and find that it is not waterproof! Water circulation is not completely cut off and there remains a real dropwise. The product is therefore unusable.

Note that I'm using a rainwater recovery system, with a booster to provide the pressure from the tank. It seemed paradoxical that when I put the blower on (so a few bars of pressure) tightness was better. But I do not always go in the garden to plug, so I sometimes use the simple gravity relative to the tank (0.1 or 0.2 bars to break everything!), And then the gun is clearly not waterproof, so useless to let the indwelling at the end of the pipe.

After returning and exchanging, bp is the same on a 2nd copy ... I move to another brand, while metal ... we'll see.
