I ran a #4 bare copper ground wire from the main shut off valve in the utility room. Stapled it to the joists then ran it through the finished ceiling in the basement to the main electrical panel. Then i installed the ground wire and landed it on the ground/neutral bar in the main electrical panel I removed all smoke detectors in the home (3. One for each floor) these were the ones you could remove the battery. I replaced them with carbon monoxide smoke detector combination 10 year built in lithium battery hard wired interconnected units (customer has a fire place) i also labeled them the date installed and the date recommended to change them out I removed a standard receptacle the wash machine was plugged into and i installed a tamper resistant GFCI
