20 liter want tank. When the mains burst in midwinter, all pipes and sewers freeze too. Most horrible situation. Mounds of frozen shit and people queuing for hours for government water. And the water must be purified (with 10 drops of chlorine). You can test the water condition yourself, if the inside of the tank feel slimy, there is something growing.
