Standard Installation of the Scalemaster Water Softener SL-S
- Scalemaster recommends that a qualified installer or engineer performs the installation. Failure to install the system as instructed could invalidate the warranty.
- Do not install if the supply water pressure exceeds 6 bar (125 psi), unless a suitable pressure reducing valve has been installed on the water supply to the softener and set to 6 bar.
- Do not install the water softener in an area where the temperature can cause the unit to freeze. Freezing temperatures will damage the system.
-
Block or Tablet Salt:
The Scalemaster® SL-S is known for its outstanding efficiency, using as little as 340 grams of salt and 25 litres of water per regeneration, making it one of the most eco-friendly water softeners available.
No Electricity Required - What Are The Main Benefits of a Non-Electric Water Softener System
-
No Electrical Costs:
Since it doesn't require electricity to operate, you avoid the ongoing costs associated with powering this Water Softener which can add up over time. -
Efficient Regeneration:
The mechanical water meter ensures that the system only regenerates when necessary, reducing the amount of water and salt used during the regeneration process. As a result, your water and salt expenses may be reduced. -
Lower Maintenance Costs:
Non-electric Water Softeners typically have fewer components that can fail, leading to potentially lower maintenance and repair costs over the life of the system. -
Longevity and Durability:
Non-electric systems are often more robust and less prone to breakdowns, which can save you money on replacements or repairs.

The Compact Water Softener That Fits Almost Anywhere
Even with its robust performance, the Scalemaster Softline SLS is designed to be compact, ensuring it fits seamlessly into small spaces, including under most sinks.

The Real Cost of Untreated UK Hard Water
Over 60% of homes in the UK have hard water, around 16m homes! Obvious signs, such as frequent equipment failures, noisy boilers, diminished water pressure, and the accumulation of chalky, crusty deposits, point to the presence of hard water. Only a water softener can eliminate this issue, and it will also clean your pipes of chalky deposits that have built up over time.
If left untreated, you may see signs such as reduced water pressure, damage to household appliances, leaking and burst pipes, poor water quality, reduction in your clothes quality, and increased energy costs. Additionally, you will almost certainly face the burden of extra cleaning to remove the unpleasant chalky deposits.


The damage caused by limescale can be both frightening and expensive. Why wait for it to happen? Invest in a Scalemaster Water Softener today.
