I picked up all of the necessary parts required to put together a new mash tun and when I went to install everything the ball valve handle hits the cooler and will not close all the way. It looks like the Home Depot cooler has a bit more of an indent than the Lowes cooler, so I was going to exchange tonight and try again. Has anybody else experienced this? Sure I could add fittings to extend the ball valve, but I like fewer parts if at all possible.
