Re: Metallic Chemical like taste.
If you use any type of soap, wash the living shit out of it. I have to use it with my base in the summer time cause of mold, I have to wash it 6 times.
If it is a stock hose, chances are it rusted and thats the root of the evil. Home depoing the hose makes it ugly as sin, but very clean and doesn't hold on to taste. When you pick your hose, it will look crazy, but its worth it. Cut a little bit off (inch or two) and suck through it and see if you taste plastic or PVC
