For the first 3 years living here we used tap water for everything, then 2 years ago i ended up at the Esnaf
with kidney stones, the same pain that you get in advanced labour so I am told. The Dr. Said it was because of the calcium in the water, after treatment to dissolve them I have always used bottled water.
Unless you enjoy advanced labour pains and begging for morphine stick to bottled water.
