Any idiot with a pair of pliers can take the flow regulator out of a consumer-grade shower head that you can buy off the shelf at any hardware store in the country and get as much water pressure as your pipes are capable of pumping into it.
Here's hoping we all still have enough money to buy shower heads in the new Trump economy so we can enjoy the fruits of his labor. Who needs prosperity and economic stability when you have a roaring torrent of water to take a depression shower like a real American patriot?
