Robert Jones Posted November 20, 2010 Report Share Posted November 20, 2010 At this mornings inspection, I ran into a leak that is a bit of a head scratcher. Above the kitchen is the master bath which has a separate tub/shower. Toward the end of my inspection, I noticed a small water spot on the kitchen window sill. There was a slooooow drip coming from the top of the window frame at both the interior and exterior of the home. I had my client go up to the bathroom and turn the tub and shower on to see if the drip got worse. It didn't, the drip just continued at a snails pace. The moisture meter went crazy just above the window trim, but not up the wall or on the ceiling above. At the exterior, the second story wall juts out a bit and the moisture meter went crazy at the lower edge. My guess is that there is a small leak from the drain line associated with the shower and the water is running on framing to exit to the area above the window. Anything else I should be considering?

John Kogel Posted November 20, 2010 Report Share Posted November 20, 2010 Good catch. The way that upstairs bathroom wall is cantilevered out, the tub and shower drains must be almost directly above the kitchen wall. The water may be running down the outside of the insulation till it hits the header above the window. Fiberglass or metal tub? tile shower? What's the age of the home and the plumbing?

Robert Jones Posted November 20, 2010 Author Report Share Posted November 20, 2010 Thanks John. Both are fiberglass units. Copper branch lines and ABS drain lines. Home was built in 1993. Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted November 20, 2010 Report Share Posted November 20, 2010 Was it raining at all (ha, like that's a question for this time of year in WA)? Could be a plumbing issue, but could just as easily be a roof leak at a pipe jack. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted November 20, 2010 Report Share Posted November 20, 2010 Brandon has a good point which I'm sure occurred to you. Just because there's plumbing there doesn't eliminate a roof leak. And a leaking vent stack is possible. I know the fiberglass shower stalls have a tendency to leak around the drain connections, probably from flexing, inadequate support under them. Nobody reads the instructions when they install them, I guess. But you did your job, found a leak. Further investigation to pin down the source. Bring in the Mike Holmes team with their sledge hammers! [] Quote Link to comment Share on other sites More sharing options...
Erby Posted November 20, 2010 Report Share Posted November 20, 2010 Was the plumbing vent stack boot installed like this? Click to Enlarge 86.53 KB Quote Link to comment Share on other sites More sharing options...

Click to Enlarge 86.53 KB That's a left-handed boot on a right-handed vent. Shoulda taken it back. Who's that other dude on the roof?

David Meiland Posted November 20, 2010 Report Share Posted November 20, 2010 You could also have warm air entering the can light and condensing somewhere in that cantilever, but I would rule out the plumbing and the roof jack first. Quote Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted November 21, 2010 Report Share Posted November 21, 2010 Who's that other dude on the roof? [] Has to be Erby's "alter-ego" ... OR ... well, you know: The Shadow Knows. [?] Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted November 21, 2010 Report Share Posted November 21, 2010 Looks like the dude on the roof is pretty "happy" Quote Link to comment Share on other sites More sharing options...
