The Puretec SOL30-E3 is a WaterMark approved domestic water softener designed to reduce hardness minerals and the scale and spotting associated with hard water.
Puretec combines a 30 L/min service flow rate with its Volumetric E3-matic valve, which monitors water use and manages regeneration according to the programmed water conditions and system demand.
The SOL30-E3 is a genuine regenerating water softener rather than a salt-free scale-control cartridge. It uses softening media, water-softener salt, electrical power and a drain connection as part of normal operation.
*Puretec bases the 12,000 litre capacity figure on incoming hardness of 100 ppm. Practical capacity between regeneration cycles changes with actual hardness and system settings.
Hard water contains dissolved minerals, particularly calcium and magnesium, which can contribute to scale deposits and spotting around water-using fixtures and equipment.
The SOL30-E3 uses ion-exchange softening media to reduce these hardness minerals before the treated water continues through the property.
Puretec specifies the SOL30-E3 for reducing calcium, magnesium and minerals associated with hard water.
Reducing hardness can reduce scale formation within compatible downstream plumbing and water-using equipment.
Puretec lists reduced scaling and spotting among the functions of its Softrol™ water-softening systems.
The SOL30-E3 is designed to reduce water hardness using ion-exchange media.
When the softening media reaches its programmed treatment capacity, the system regenerates using brine made from water-softener salt. The regeneration process restores the media so it can continue reducing hardness.
This is different from cartridge-based scale-control media, which can help manage scale formation without removing hardness minerals through ion exchange.
Puretec's E3-matic valve monitors water consumption and uses the programmed water conditions to determine when regeneration is needed.
Puretec states that if water is not being used, the E3 system does not simply backwash unnecessarily. When regeneration is required, the control system calculates the cycle around water volume used and the programmed water quality information.
Puretec currently lists the SOL30-E3 with a nominal capacity of 12,000 litres based on water hardness of 100 ppm.
That does not mean every installation will treat exactly 12,000 litres between regeneration cycles. Harder incoming water consumes the resin's working capacity more quickly.
Puretec's current SOL-E3 installation guide includes an installation record for incoming water conditions including:
Puretec notes that its softeners are designed to reduce hardness and can handle reasonable amounts of soluble iron where the iron content is considered during model selection and regeneration setup.
The SOL30-E3 is not a salt-free treatment system.
Water-softener salt is used during regeneration to restore the ion-exchange media after hardness minerals have been captured.
Puretec's current SOL-E3 guide lists a maximum salt storage capacity of approximately 50 kg.
The salt level needs to be checked and replenished as required. Consumption varies with hardness, water use and regeneration frequency.
Puretec lists a free-chlorine tolerance of 1 ppm for the softening resin.
The manufacturer warns that high chlorine levels can permanently damage the resin and recommends a carbon pre-filter when chlorine exceeds this level.
Puretec also recommends carbon pre-filtration more generally to help protect the softener against chlorine spikes and prolong resin service life.
Puretec specifies that the water softener should be installed in the water supply line before the water heater.
The system should also be positioned as close as practical to a suitable drain while retaining enough access for servicing, control-valve access and salt replenishment.

The SOL30-E3 is not an under-sink drinking-water filter. It is a full-size point-of-entry softener requiring dedicated installation space.
Allow additional room for plumbing, electrical connection, drain and overflow lines, control-valve access and salt replenishment.
Puretec lists an operating pressure range of 138–862 kPa for the SOL-E3 series.
Where line pressure exceeds 500 kPa, the manufacturer requires an approved pressure limiting device to comply with applicable Australian and New Zealand plumbing requirements.
Puretec's current SOL-E3 user guide lists an electrical connection of 240V / 50 Hz.
The installation instructions specify a non-switched power source for the control valve so the E3-matic system can monitor water use and operate its regeneration cycles.
The SOL30-E3 regenerates its treatment media and therefore requires permanent drainage.
Puretec's current SOL-E3 guide lists a 5/8" drain connection and a separate 5/8" overflow connection.
Puretec's current guide states that installation should be completed by qualified tradespeople and that plumbing must comply with applicable local requirements.
For point-of-entry installations, Puretec also specifies an approved backflow prevention device.
The SOL30-E3 is designed primarily for hardness reduction.
| Feature | SOL30-E3 | SOL40-E3 |

| Cabinet Dimensions | 1125 × 350 × 490 mm | 1125 × 350 × 490 mm |
Both models use volumetric E3-matic control. Choose between them using actual peak flow, incoming hardness and treatment demand rather than household labels alone.

Purchase the Puretec SOL30-E3 without installation where you already have an appropriately qualified installer.
Flow, capacity, dimensions, pressure, salt, drainage and pre-filtration requirements are matched to current Puretec product information.
Installed Today can also support eligible local installations where water conditions, plumbing, drainage, power and site access are suitable.
The Puretec SOL30-E3 Softrol™ Water Softener is designed for properties requiring genuine hardness reduction with a service flow rate of up to 30 L/min.
It uses Puretec's Volumetric E3-matic valve, has a nominal 12,000 litre capacity at 100 ppm hardness, requires salt, power, drainage and overflow provision, and measures approximately 1125 × 350 × 490 mm. Puretec lists the dry weight at 29 kg and maximum salt storage at 50 kg.
Before ordering, test the incoming hardness and other relevant water conditions, confirm 30 L/min is appropriate for the property's demand, provide suitable 25 mm plumbing, drainage and electrical supply, and consider Puretec carbon pre-filtration to protect the softening resin. Where greater service flow and softening capacity are required, the SOL40-E3 provides the corresponding 40 L/min volumetric option.
