R/O Pump System - Reverse osmosis from Silverline UK

The pumped reverse osmosis system comprises:

Sediment cartridge for particle filtration
Carbon cartridge to protect membrane from chlorine
Membrane housing with TFC membrane giving high rejection levels of unwanted water elements
Post filter for final polishing of the water
3 gallon stainless steel collection tank
Electronic solenoid valve to prevent overfilling
Pump to guarantee efficiency regardless of water pressure
Deluxe ceramic dispensing tap and plumbing connection both with tube attached for easy installation.

The system is connected to the mains water pipe under the kitchen sink using a self piercing valve.  To ensure water is not wasted on washing up and cleaning a separate drinking water tap is provided.  Both the pipe connector and tap have tube attached which push into the system inlet and outlet respectively.

How it works

Water passes from the cold water supply into the pre filters where dirt particles and chlorine are treated.  It then passes into the membrane where clean water can pass through and contaminants are rejected and sent to the drain.  The treated water passes into the post filter for final polishing then into the collection tank for later usage.

Maintenance

With the exception of filter changes there is virtually no maintenance.

The prefilters should be changed every 6 months as these protect and prolong the life of the membrane.
The post filter should be changed yearly.
The membrane life will vary depending on water quality and volume treated.  The more work the membrane has to do the shorter its life hence the value of regular prefilter replacement. Expectancy is 2 to 5 years.
