I'll also add a warning about cheaters. Wrenches aren't always made for that extra torque and they do break. If you must use one, assume something will break, and plan for what your hand will punch, and where the broken pieces will fly. Actually that's good advice anytime you put torque on a wrench.
An aside: I grew up helping my father at his plumbing shop. He had a collection of large iron pipe wrenches with bent and broken handles and taught his sons not to use cheaters. Heat and impact are your friends. But of course I didn't learn that lesson until I put a 5' cheater on a 24" wrench on an overhead pipe, pulled down on it, right onto my head when the wrench broke. That left a mark, and lasting respect for Dad's advice.
