Customer stated: they had a leak in the hallway ceiling firm the guest bathroom above. Tech notes: called out today to look at a leak in the ceiling. While on site I found the leak was below the guest bathroom bath tub on the second level. I ran water and found the leak was coming from the over flow gasket in the bathtub. Resolution: I tightened the over flow to secure the over flow to the tub. After doing so I turned water on and tested to find no further leaks or drips. Job status: complete.
