This may sound paranoid but I always put it in a bucket of water for a few days and then dump the bucket rinse the pipe and then throw it in the tank (hoping that anything that might leach out in high quantities does so quickly. Even though I assume that since it is made for the pipes that the water we drink goes through the glue would not really leach anything really toxic...but they do sell us sodas/beer in aluminum cans and that is not exactly the best for us *insert rant on how our bodies cant process out some of the metals that the soda will leach out of aluminum cans*) Now that I have officially made myself sound crazy today I will be quiet lol
