How Hard Water Causes Blockages
When hard water flows through your pipes, the minerals can stick to the inside surfaces. Over time, this builds up into limescale. Think of it like cholesterol in arteries — at first it’s barely noticeable, but eventually it can restrict the flow of water.
This narrowing of pipes creates the perfect conditions for other materials to stick and form a blockage. Hair, food scraps, fat, oil, and even small bits of debris can all cling to the rough limescale coating. What might have flowed straight through a smooth pipe ends up sticking — and before you know it, you’ve got a slow drain or a complete blockage.
