What you get
SKU: RO40
Product Description

Water feed 40L / hour

The system is direct flow but can also feed a header tank from which you draw your water.

Min incoming pressure required is 4 BAR

(NB the unit does not have an inbuilt pump.

Watch out for a small pressure loss if using a softener - recommended in hard water areas read more.

If so you’ll you need between 4 and 6 Bar).

Be careful of any RO that claims to produce 40L or more per hour at anything less than 4 Bar, (for example ones that says 2.5 BAR). They usually simply don’t work and you’ll be disappointed.


Full instructions are provided. A competent plumber should easily be able to fit this unit. Understanding the principle of how RO works ie setting level switches and understanding RO waste water etc is helpful but not essential.

The electrics are no more complex than wiring a central heating system.


Please don't hesitate to contact us to discuss your requirements.

Cartridge Changes

There are 3 pods on the unit. Two of them are for membranes, The other is for the pre-filter. A fourth, the carbon postfilter, is used to "polish the water" after it's left the unit.

The frequency of renewing the cartridges depends on the quality of the incoming water.

Typically the pre-filters are changed annually and membranes on good quality, mains water every 2 years. On bore hole water it could be annually.

You will know when to change the membrane from your TDS readings - the level depends on your preference and the RO's applidcation. It will also depend on the amount of water being used. For example you might be drawing 20 litres a day or 200 litres a day.from the unit. The more you use it the more frequently you'll need to change the filters


Conductivity

The RO membrane is rated at 22% efficiency

So if it's 100 coming in for example it will be 78


Costs
