I see a lot of toilet that stick from sitting with mold on them. these parts in the tank can break if you push it... the same with all the faucets in a home. dish washer if its been sitting for some time look out . get the agent to sign off that you assume no part of the inspection if you are going to go around and turned on all the faucets and toilets, dishwasher. if something sticks or will not shut off you got a problem.
