Plumbing issues

Ron discovered that our kitchen sink pipes are leaking. Of course it’s a weekend!
He put up this caution tape because it is so easy otherwise to mindlessly turn on the water to wash your hands or wash a dish or veggies. So no running water down the drain. No dishwasher or garbage disposal either.
Ron called a plumber around 9:30 am and their answering service said a plumber would call us within the hour.
Nope, no callback at all.
Grumpy!
