The MiniMax Major Water Softener Review Score & Rating


Summary: What’s Great About This Softener 

High Flow Rate. Great Warranty. 

The Harvey MiniMax Major is designed for large homes and therefore has a high maximum flow rate of 80L/min. It also comes complete with a 10-year warranty.

Summary: What’s Not So Great About This Softener 

Hard to Source. Large in Size. Lower Pressure.

This water softener is sold within an exclusive dealer network. Therefore, it can sometimes be hard to come across. It has the same specification as other Harvey models such as the TwinTec XL1 and HVX, but the prices of these products are not the same. It comes in two compartments, the softener and a brine tank. This can make the softener a little more difficult to install and you need a lot of space. It also has a maximum operational pressure of 6, which is slightly lower than the HVX and XL2.

The Pros 

  • High capacity and flow rate.  The Major has a flow rate of 80L/min – one of the highest flow rates available. Perfect for larger homes.
  • Non-Electric. With lower running costs.
  • Twin Tank Design. You’ll have soft water 24 hours a day.
  • High salt capacity. Standard water softeners can hold 20kg of salt at any one time. 
  • Designed for large properties. Meaning you won’t see a water pressure drop.

The Cons 

  • Lower operational pressure of 6 bar.
  • Large size. This softener is large with two compartments. That means you need to be sure you have space.
  • It is more expensive.
  • Is similar to other models. Including the HVX. What’s more, the Harvey Big Blue also appears to be more efficient so a better option for the same price.
