Yucatan has very hard water both from private wells and in public water supplies. This hard water ultimately always leads to a steady build-up of scale / Calcium carbonate / CaCO3 (sarro) on the flapper valve in the bottom of flush toilet tanks (this valve is called a sapo = toad in Mexico – also called a toilet flush valve in the States.)

Your Toad / Tu Sapo

When sarro builds up on your sapo, it causes the flapper valve to leak slightly all the time. These slight leaks drain your tinaco (water storage tank),  and stain  toilet bowls with streaks of sarro and sometimes with streaks of iron stains. . . . (cont.) . . . enough to make a virgin blush….
