"Every time I vacuum the electrical breaker trips. I know my rights, I don't have to pay rent till you have the house re-wired!"
Blanket statements are never a good idea from either side of the situation. It instantly puts everyone on defense. In this situation, the manager sent over an electrician right away, and the solution was simple. The tenants had been using multiple adapters on EVERY outlet and were completely overloading the circuits in almost every room in the home. The wiring was just fine and completely safe for the building. The tenants not only had to pay rent, but were responsible for the late fee's AND the cost of the electricians visit.
