Hard water causes scale accumulation in your plumbing, just as it does in your water heater. Also, nobody likes accumulation in their plumbing. This shortens the lifespan of your plumbing in addition to reducing the diameter of your pipes, which restricts flow and efficiency. You’ll appreciate the absence of buildup the most from a water softener. This will improve the life of your pipes while also lowering the likelihood of unpleasant and nasty clogs.
