Hello pipe experts. I know one of you can help me. I just bought a Grabow Viking cheap on the Fleabay. One problem - I can’t remove the bowl. I know it is threaded and should unscrew, but I’ve given it what I think is the most force I possibly can without bending the aluminum base and it still won’t come off. It does wiggle left and right just a tiny amount, so it doesn’t seem to be stuck, though it does look pretty grimy where the bowl connects to the base. Any ideas? Is it just lefty loosey and give it hell?
