Another suggestion is to keep track of all of your work orders. If the guest mentions that a toilet is running, write it down. Then two months later when there is an additional complaint, you can determine if it came from the same toilet pointing to a larger issue. Spreadsheets like the example shown here, don't provide a ton of value short term, but they are invaluable over time.
Imagine providing detailed records of every little maintenance item and replaced equipment in one place when you go to sell the property. This would be very valuable to a prospective buyer.
Track your work orders to identify trends in a form like this one.
