This Reverse Osmosis Undersink 5 Stage model PSI-021-5RM-HA is a premium low waste 1 to 1 ratio unit featuring the exclusive membrane flushing with a full size Hi Alkalizer re-mineraliser. This re-fillable alkalizer system will produce water with an alkalinity of 8.5 to 9.5 pH. customers report the average is 9.3 pH
It has the Dow Filmtec 300 litre per day TFC membrane, the 300 litres is rated at 50 psi (350 kpa) but will produce up to 450 litres per day higher pressures, what this means is the system will fill faster than most systems on the market. This system has an auto shut-off device that closes off the in-feed supply when the storage tank has filled.
All components are NSF certified to standards 042, 053 & 058
Replacement trio of cartridges (ROCDU-02) which is the annual change are $50.00, how often the alkalizer will need to be re-filled will depend on usage, this will normally ocour about every second year with the cost of the re-fill $20.00 if ordered with other cartridges.
Supplied with QMP-300-HP U.S.A. made housing 10" Australian Standards AS3497 with 1/4" NPT threaded ports. This housing is tough with a burst strength of 575psi (4000kpa) and is tested to AS3497 which means it has been tested from 0 to 700kpa and back to 0 kpa 100,000 times without failure, cracking or distortion.
With these premium systems we supply the 550 kpa pressure limiting valve with dual check valves which is a plumbing code requirement, the valve is also Watermark AS1357-2 licence no 02596 as the watermark is also a plumbing code requirement.
We supply the 550Kpa PLV with the premium system so the filter system runs faster than other units on the market.

The re-mineraliser (Alkalizer) which contains crushed Marble or crushed Limestone and coral sand. The material contained in the cartridge is mostly calcium but also contains trace elements of other minerals, this is the same material suppied with what are called Pi systems or Alkalizers, we are prevented from supplying a specification sheet as the amount of re-mineralisation is dependant on the pH of the water, if we had the unit tested at say a pH of 6.0 the cartridge would result in an X factor of re-added minerals which would be misleading if the water in your unit on your water supply had a pH of say 6.4 before the re-mineraliser which would result in a lower added amount.
The re-mineraliser cartridge in this unit can be un-done and some of your own media can be added if you wish.
The re-mineraliser cartridge contains 2/3 crushed calcite (marble) and 1/3rd coral sand, the coral sand is the component that puts the pH up, you can add extra if you wish to go higher in pH. The coral sand will dissolve away over time and to maintain the high pH this will need extra added at times, you can purchase additional coral sand if you wish at $20.00 per kilo. The calcite is normally replaced after the 4th year.
The reverse osmosis process can't pick the pepper out of the salt so to speak, so it is better to be sure and remove all the poisons from the water than be worried about the minerals that have been removed. Health experts say that you obtain the minerals that your body needs from your diet, you should not rely on water as a mineral source as there is very little available to the body in water as the minerals are totally dissolved, the re-mineraliser in this system is about balancing the pH as a taste issue.
Main filter unit size, 42 cm high, 42 cm wide & 14 cm deep. 9 litre stainless steel storage tank (exceeds drinking water guidelines) NSF Certified. If space is an issue we also offer a 4.2 litre or 12 litre tank.
Premium systems now have the lowest waste ratio of all systems on the Australian market, using a Patented combination membrane flushing valve/flow restrictor means the waste ratio is about 50% less waste than other brands, waste ratio is now about 1 to 1.
Installation choice 1/2" tee olive fitting, 3/4"dishwasher adapter or 1/2" easy fit braided line flick mixer adapter, our systems take the average handyman 1/2 to 1 hour to install
550 kpa pressure limiting valve, genuine QMP Stainless Steel dedicated faucet. Housing spanner to ease cartridge changes. Replacement set of cartridges.(3) $60.00, less 20% if a replacement set is ordered with the unit.

If you option to have the hand held TDS meter with the unit beware that the system will have an elevated reading due to having the reminerliser cartridge.
All reverse osmosis systems require a minimum pressure of 40 psi (280kpa) with 50 psi (350kpa) or more is ideal. If you are unsure what your pressure is check with your local Council or water authority.
Operating pressure requirements 280 to 550 kpa (40-80 psi)
