The unique features of a Harvey™ Water Softener:Type of salt

Water softeners will either use tablet salt – pebble size supplied in 25kg bags or block salt – house brick size, supplied by Harvey™ in 8kg packs. Block salt is becoming increasingly popular due to ease of handling, storage and loading.

Electric vs Non-electric

Electronically operated water softeners are cheap to produce, whereas non-electric last longer and are more reliable.

Number of cylinders

All water softeners have either one or two cylinders to house the softening resin. Only those with two cylinders can guarantee softened water 24/7 as there is no downtime during the cleaning process, also known as regeneration. Those with two cylinders are also more efficient with salt usage.

Time vs Meter control

Budget water softeners will use a simple timer that requires regular programming, compared to a good quality water softener, like a Harvey™ Water Softener, that will monitor water usage with a meter and make adjustments based on your consumption.

Type of meter

The Harvey™ Water Softener uses a displacement meter that is also used by the water board for measuring household water supply. They are tried, tested and the most accurate and reliable type available

Easy check salt lid

Salt needs to be checked regularly, so a simple solution is best. Some water softeners require the unit to be opened whereas others, such as the Harvey™, has a clear section that shows the level.

Programming required

Electric water softeners will require setting up and programming for water usage, water hardness and some other settings. A non-electric water softener does the job for you with its factory preset, making it easier to use.

Cylinder operation

Twin-tank water softeners often use a service / standby method, where one cylinder will always stand idle ready to take over when the other is exhausted. The Harvey™ Water Softener uses a duplex parallel method that allows both cylinders to be used, except for when one is regenerating. This results in a better flow rate.

WRAS approved

The Water Regulations Advisory Scheme (WRAS) is a mark of approval that demonstrates an item complies with the high standards set by water regulations published in 1999 in the UK. Enforced by the UK water supply companies, it covers all plumbing systems, water fittings and equipment supplied with water from the public water supply. It is a legal requirement for products installed in the UK to comply with the Water Supply (Water Fittings) Regulations 1999.

Softened water guarantee 24/7

Single-tank water softeners can’t regenerate and soften your water at the same time, so there will be times that hard water flows into the system. If you’ve got loft tanks, the softness of your water can be compromised for days afterwards. Twin-tank water softeners. such as the Harvey™ Water Softener, don’t suffer from this problem, they keep softening 24 hours a day, seven days a week.

Maximum flow rate

This figure indicates the maximum amount of water that can flow through your water softener in litres per minute. The higher this figure, the better your water softener can cope with power showers, combination boilers, mega-flo systems and high water usage like multiple showers being used at one time.

Salt used per regeneration

An indicator of how much salt your water softener needs to clean itself under normal circumstances. This figure is only useful when combined with the capacity of your water softener and other factors to do with property and usage. The same applies to salt used per regeneration.


Size does matter. At one point water softeners would stick out through a hole in the kitchen surface, now a days they are a lot more compact. The Harvey™ Water Softener is designed to fit under the kitchen sink, meaning it can fit into many other convenient places in the home, such as in a garage, utility room or even loft if needed.
