I replaced the garden hose onto my outside spigot. Now it leaks from the spigot/hose connection. I then purchased a threaded pipe extension to hook the garden hose onto that but still it leaks from the spigot/hose connection.

I never had a leak with my old hose and as I also tried the pipe extension and the new hose and both give me leaks I am at a loss.

Any advice?

Thanks in advance
