Took me 3 hours to figure out why the roof drain kept backing up on a Denver job
We had a 4 inch cast iron roof drain on a 12,000 square foot warehouse in Denver that kept overflowing every time it rained hard. I snaked it twice, ran a camera down 40 feet, and everything looked clear, so I started thinking the whole line was undersized. Turned out a crew had poured a concrete patch over a broken cleanout plug about 6 feet from the drain, and water was pooling there and backing up the whole run. I found it by accident when I tapped the slab with a hammer and heard a hollow spot, and popping that patch took 20 minutes after 3 hours of guessing. Anyone else run into a hidden cleanout buried under concrete, and how do you track those down without tearing up the whole floor?

Hidden cleanouts under slab are the worst. Been there, tapped a floor for an hour before finding one under a 2 inch pour near a mop sink. Now I listen for hollow spots first thing on any backup that snakes clean. Cheap trick, saves hours.
