The shower drain has been real slow the last couple of days and yesterday it stopped almost completely. So I called the super who came by and tried to solve it but the clog was still there this morning.
When he came up today he had a bottle and a half of some dark liquid with the "Skull and crossbones" signs all over it. After pouring it all in, visable fumes coming out the drain it seems to have worked. But can it be environmentally sound to pour 1.5 litres of concentrated sulfuric acid or other chemicals down the drain every time there is a severe clog??
