Monday at our house was extra fun. We had water dripping from the upstairs bathroom to the downstairs bathroom. The plumber came over to see where the problem was leaking. The hole on the right was to see if the shower drain or the faucet was leaking. It was fine
The other hole is where the leak was. Have you ever noticed the white pipes that stick out of your roof? Apparently that is connected to your sinks, showers and toilets somehow...until it isn't. Then you get water leaking into your downstairs bathroom...and you have multiple holes in your walls. It's pretty fun
