Do bacteria grow in a water softener?

Non-harmful bacteria grow in water softeners. Bacteria can be found everywhere and particularly in substances where there are minerals, such as water. They are completely harmless and, in a lot of cases, help us to function as living things.

Does a Harvey™ block salt water softener have a maximum daily capacity?

A Harvey™ twin cylinder water softener doesn’t need a maximum daily capacity. Our water softener regenerates while still softening your water, making the capacity endless. One water softener will guarantee softened water 24/7, regardless of how much you use. This means you haven’t got to calculate your capacity requirements or change settings for usages, making

How much water flows through the softener in between regenerations?

The amount of water used between regenerations depends on the hardness of your water supply. Typically, we’ve measured that around 402 litres of water flows through the water softener between regenerations. The process of regeneration uses 17 litres of water, this is unaffected by your water hardness.

Does a Harvey Water Softener™ use a ‘backwash’?

Harvey Water Softeners™ do not use a backwash cycle to fit with British design criteria and save water. A backwash cycle is a feature of American manufactured water softeners. Many of the water supplies throughout the USA are from private boreholes, making the water quality extremely varied and unpredictable. Finding dirt in the water, or

What actually happens when you soften water by ion exchange?

Domestic softeners typically treat the water to the whole house. They are salt-regenerated, ion-exchange units which contain ion exchange resin. This resin contains sodium ions which “swap places” with calcium (together with magnesium and some other trace metal ions such as iron and aluminium) as the water passes through. So calcium and magnesium are taken

Why does it take 17 litres of water to regenerate a Harvey Water Softener™?

The water is used to drive the brine (salt solution) regenerant through the water softener and then flush it ready for the next service cycle. The number of litres used for each regeneration is dictated by the design of the water softener, its size and efficiency. The water softener needs a specific amount of salt

How long is the life of the resins?

Longer than necessary. The machine is more likely to wear out before the resin. The old fashioned water softeners had their resin changed periodically. The new water softener will not need this during its normal lifetime.
