I am trying to locate a leak that has reappeared.
The leak appears on my kitchen countertops, it actually is leaking on top of one of my corner cabinets. Theres a bit of a gap between the cabinet and the soffet and I can see it.
Immediately above the cabinet there is:
- master bathroom - Original to 1970s house.
- guest bath - redone this century
- associated drain/vent stacks
The original 'fix' for this leak was a year ago under my home warranty. Plumber determined that the tub, drain, etc. were sealed but there was a leak/gap in the linoleum floor in the master bath. The leak was not leak, rather just people being wet or splashing in the bathroom. This was not covered by the warranty (different topic), so I got a tube of silicone caulk and sealed the gap and the entire edge of the linoleum floor.
This leak reappeared today. I pulled the tub drain and overflow cover and resealed with plubmers putty. Its raining, so I went in the attic and checked that the vent stack was dry. I also filled and drained the guest bath tub.
My primary suspect is this unsealed floor again. What else should I investigate?
I could care less about the master bath, I do care about the nearly new cabinets in my kitchen and inside-the-wall water damage.
