The Puretec SOL40-E1 is a WaterMark approved domestic water softener designed to reduce water hardness, scale and spotting throughout a home or building.
It uses Puretec's Automatic E1-matic valve with time-based regeneration at programmed intervals. Puretec lists the SOL40-E1 with a 40 L/min service flow rate and a nominal 18,000 litre capacity based on 100 ppm hardness.
The SOL40-E1 is a regenerating ion-exchange softener rather than a cartridge-based antiscale system. It requires water-softener salt, drainage and electrical power as part of normal operation.
*Puretec lists 18,000 litres based on water hardness of 100 ppm. Actual capacity and suitable regeneration frequency depend on incoming hardness and water use.
Hard water contains dissolved minerals that can contribute to scale deposits, spotting and mineral residue.
The SOL40-E1 uses ion-exchange softening media to reduce hardness before the water continues through the property.
Puretec specifies the SOL40-E1 for reducing calcium and other minerals associated with hard water.
Reducing hardness can reduce scale accumulation on compatible fixtures, plumbing surfaces and water-using equipment.
Puretec lists reduced scaling and spotting among the key functions of the Softrol™ range.
The SOL40-E1 is designed to reduce hardness minerals through a regenerating water-softening process.
This is different from cartridge-based scale-control products that leave hardness minerals in the water while changing how those minerals behave.
If the objective is measurable hardness reduction rather than scale management alone, a regenerating softener such as the SOL40-E1 performs a different treatment function.
The SOL40-E1 uses Puretec's Automatic E1-matic valve.
Puretec describes the E1 system as using automatic, time-based regeneration and backwashing at programmed intervals.

| Service Flow | 40 L/min | 40 L/min |
| Current Listed Capacity | 18,000 L at 100 ppm hardness | 18,000 L at 100 ppm hardness |
| Regeneration Efficiency | Regenerates according to programmed timing | Puretec states the volumetric valve backwashes only when needed based on consumption |
Puretec currently lists the SOL40-E1 with a nominal capacity of 18,000 litres based on incoming hardness of 100 ppm.
This should not be interpreted as a fixed 18,000 litres between regenerations for every property. Higher hardness places greater demand on the resin and changes the required regeneration schedule.
Regenerating ion-exchange softeners use water-softener salt to restore the treatment media after hardness capacity has been consumed.
The salt level therefore needs to be checked and replenished as part of normal system maintenance.
Puretec specifies a free-chlorine tolerance of 1 ppm for the softening resin.
High chlorine levels can permanently damage the resin. Puretec recommends carbon pre-filtration if chlorine exceeds this limit and also recommends a carbon pre-filter more generally to help protect the resin from chlorine spikes and prolong its service life.
Targets water hardness and associated scale.
Can provide separate sediment and carbon treatment before water reaches the softening resin.

The SOL40-E1 is not a compact under-sink drinking-water filter.
Puretec's current SOL40 cabinet dimensions are approximately 1125 mm high × 350 mm wide × 490 mm deep, so the installation needs dedicated floor space together with room for plumbing, drainage, power and future servicing.
Puretec lists the SOL40-E1 for an operating pressure range of 138–862 kPa and an operating temperature range of 0–48°C.
The current product specification lists a 230V AC / 50 Hz power supply for the electronic control system.
Where incoming line pressure exceeds the applicable plumbing limit, suitable pressure control should be incorporated as required by the installation.
The SOL40-E1 requires drainage because regeneration and backwashing discharge water from the softener.
The installation location therefore needs suitable access to drainage as well as the incoming and outgoing water connections.
A water-treatment system may combine pre-filtration and softening where the property requires both contaminant treatment and hardness reduction.

Installed Today can also support eligible local installations where water hardness, plumbing, drainage, power and site access are suitable.
The Puretec SOL40-E1 Softrol™ Water Softener is designed for properties requiring genuine hardness reduction with up to 40 L/min service flow.
It uses Puretec's Automatic E1-matic time-based control valve and is currently listed with a nominal 18,000 litre capacity at 100 ppm hardness, WaterMark approval, 1" Male BSPT connection, 138–862 kPa operating pressure and 230V AC / 50 Hz power requirement.
Before ordering, confirm the property's actual water hardness, available installation space, plumbing size, power and drainage. Allow for ongoing salt replenishment and consider suitable Puretec carbon pre-filtration where chlorine protection is required. If regeneration based on actual water consumption is preferred, compare the SOL40-E3 volumetric model before selecting the final system.
