Customer had a leak coming from upstairs vanity p trap and was leaking into garage ceiling. I cut out sheet rock and found leak. Removed p trap and cleaned seals. Reinstalled and tightened slip joins. Leak stopped. Also noticed there may be a leak in the clothes washer. I let homeowner know we do not work on or troubleshoot appliances. Water heater is also leaking. Pan has a half inch of water in it. Customer did not want to take care of this today.
