Removed disposal after disconnecting plumbing. Removed supporting bracket and old splash guard. Pushed new guard onto top of disposal, reconnected supporting bracket. The hard part was pushing the disposal back onto the support bracket and rotating it into place. Disposal is heavy and I needed to lever it into position and hold it with the lever, it takes two hands to rotate the disposal tight. I am not fond of plumbing; I always seem to have a leak after trying to fix something. So far so good!
