(WEAU/WLAX) Many people know the Friday after Thanksgiving as “Black Friday,” the most popular shopping day of the year – but it’s also the busiest day of the year for plumbers. In the plumbing industry, it’s known as “Brown Friday,” thanks to the increased use of kitchens and bathrooms during food preparations and large gatherings.

Master Plumber Andy Besch with Besch Plumbing in Appleton was booked for Friday.

“We help, help what we can, where we can,” he said. “We help people that we can. Make people happy. It’s what we try to do.”

His schedule was flooded with appointments to unclog drains and pipes that had been abused the day before on Thanksgiving.

“Everyone runs stuff down the disposal that they shouldn’t,” he said. “I never understood the idea of introducing food into the plumbing drain system, but here we are.”

While most plumbing services aren’t open over the holiday weekend, many like Besch have staff on call for these annual emergencies.

“I always plan to work usually every year. So it is what it is,” he said. “That’s what we do. So our job plumbing doesn’t care when it breaks; doesn’t take a day off.”

Despite warnings from plumbers, Besch said people tend to make the same mistakes every year and throw things down the garbage disposal that don’t belong.

“The disposal can’t chew it up, it gets stuck in the plumbing system. And here we are,” he explained.

With Christmas right around the corner, Besch said the season for finicky plumbing has just begun. He cautioned people to think twice before throwing food down the drain.

“Throw food in the garbage best thing you can do,” he said. “Stop running food down your disposal.”

He added that when something does go wrong, let the professionals handle it.

“Call a plumber,” he said. “Don’t try to plunge the drains that makes it even worse. You can damage the drainage system by plunging it.”
