We had a mini disaster earlier this week, a flash flood came out of nowhere and flooded my under-slab plumbing.
That morning the plumbers had started installing the drain lines.
I had measured out and put strings to mark all the locations of the interior walls-this way the plumbers can see where to stub up the pipes so that they’re in the walls.
Here you can see where they brought up a 2” pipe out of the main 3” line for a bathroom sink.
They primed and glued all the fittings and then used a torpedo level to make sure the pipe would be plumb.
Next, they bedded everything with crushed stone, the stone keeps the pipe from settling and holds it in place, so we maintain our ¼” per foot fall.
I had set-up an inspection for the next morning, so we filled all the pipes with water for a hydrostatic test.
And I’m so glad we did because I think it would have all floated out of place and been destroyed if we hadn’t.
Right as we finished up, we got some of the hardest rain I have ever seen.
I had covered the sewer sleeve with a piece of plywood and a tarp, but water still came through and flooded the ditches.
Thanks to my Milwaukee pump- I had it cleaned out 5 hours later and passed my inspection the next morning.
Let me know what’s the worst weather-related jobsite disaster you’ve seen? @hausplans
