Luckily, this water softener is delivered with its mounting bracket. However, this Hard Water Bullet won’t remove iron and chloramine. Further, since the inlet comes with a 1-inch diameter., you might require some additional connectors.

Hard Water Bullet filter will stop the sediments but minerals wull readily go through the filter’s polyphosphate coating. But why polyphosphate? Well, polyphosphate will prevent the sticking of hard water minerals onto surfaces such as pipes.

Do salt-free water softeners work?

Water softening involves replacing magnesium (Mg2+) and calcium (Ca2+) ions with sodium ions (Na+) from your well water using a polymer resin (that’s actually negtaively charged). The softeners don’t require regeneration cycle or even salt to remove drain the minerals.

Well, salt-free water softeners will simply condition the hard water minerals. Conditioning, in this case, implies transforming calcium and magnesium ions to prevent them from precipitating into scales or clinging on your pipes.
