I removed and replaced three carbon monoxide smoke detector combos with Company supplied hardwired 10 year lithium battery interconnected carbon monoxide smoke detector combo units due to the fact the previous units would randomly go off causing the customer much headache especially in the middle of the night Customer had a broken switch that controls the garbage disposal that was in a three gang box the existing switches were ivory so I recommended to replace all switches with new white switches any brand new white three gang switch plate and the customer decided to move forward with this option I removed and replaced the GFCI outside underneath the back deck with a weather resistant tamper resistant GFCI a new in use bubble cover due to the previous GFCI was not rated to be outside and it was damaged
