We had the roof replaced two years ago. I believe they redid all the flashing at that point. So there's a chance this could be old? If the leak is resolved, which I'll verify, do we have to do anything to the wood or are we good?
I am lucky. I had no idea this was going on back here. Here's the back of the scorched cabinet.
And here is my new cap job.
I'm going to cover it with a plate and cut a hole in the melamine just as you suggested.
The blue box is one of those kind that is supposed to latch into the drywall, but the melamine is cut too tight for that to have ever worked so it's just busted out when I pulled on cabinet.
And I assume the line branches before it travels up into the walls? Or is there a chance it branches after it leaves the crawl space, in which case you could consider opening a wall for the valve.
I can't imagine it would be more than a couple hundred bucks assuming they can find an accessible point for it. Mine is in an unfinished room at the corner of the basement where the main line comes in and replacing it took the plumber life twenty minutes.
You can ask the plumber about coordinating with the city for shutoff. Maybe they'd know a guy?
But definitely don't mess with it if. In my case I couldn't find my external shutoff when I needed that internal one replaced so I had the city come locate it for me. They uncovered the plate, tested the valve and it broke immediately. Fixing it was a major excavation. The city guy told me how lucky I was that I hadn't found it and tested it myself.
Hejsan! Jag är amerikan men bodde jag i Sverige några år sedan. Tack så mycket för dina råd. Det kan var lättare i Sverige för sådana saker, tror jag.
