Shut the main off to several units to put on a new main ball valve to your unit. Also put on the washing machine valves that you provided. Don’t forget to reset the toilet on the main floor. It rocks quite a bit. The bolt on the right side is completely gone and the left side is fairly rusted. The flange in the floor may need to be rebuilt, but unknown until the toilet is taken off to take a look at it. Wishing you both the best in your new home. Mark, with Southside Plumbing.
