Water Softener Salt Usage Guidelines

Keep Your Water Always Soft: Never Run Out of Salt.

Do you want to know how long your Harvey Block Salt will last?

Making sure your water stays nice and soft means never running out of special salt for your water softener machine. When the salt runs low, your water might not feel as nice and smooth and you will start to feel hard water again. But don't worry! We have designed this guide so you know how much salt you should buy to help you keep your water super soft all the time.
