The black water you see is normal. The filters made with a carbon block require flushing when initially installed. Rinse a number of litres until the water is clear to remove any excess carbon flecks.
The filter indicator is not trigged via the filter itself. Usually the filter indicator turns on after an amount of water has been dispensed, or after an amount of time. Therefore, changing the filter alone will not reset the filter indicator. To reset the indicator, refer to the manual for your fridge, or contact the manufacturer with the model number of your fridge.
Below are the common filter indicator reset instructions.
Whirlpool and KitchenAid
Press the light switch 5 times within 10 seconds. If the fridge has a filter button, press and hold it for 5-10 seconds.
Press and hold the reset button for 3 seconds.
Press and hold the lock and light buttons at the same time until the filter indicator flashes (about 4 seconds).
On newer models, press and hold the lock and water buttons at the same time until the filter indicator flashes (about 4 seconds).
Press and hold the ICE TYPE and CHILD LOCK buttons for 3 seconds. The water filter indicator should turn green. NOTE: Only hold these buttons for 3 seconds. Holding these buttons for 5 seconds cancels the reset. If you cancel the reset, repeat the procedure.
We do not advise using the waste water to put back into the system. This is because the concentration of contaminants will be higher in the waste water, this would wear down the filter components more quickly.
Our MB-151 resin is specially formulated for hard water (high TDS) areas where our regular MB-115 resin would become a lot less effective very quickly, as the contaminants in the water would wear it out a lot faster. MB-151 meanwhile is designed to function correctly even with the worst possible water qualities. It can also be used in areas with good or average water qualities without fault. This resin is also used when a reverse osmosis system is not used.
The MB-115 resin is designed for soft water areas, or for use after a reverse osmosis unit.
The taps are for mains hot, mains cold, filtered/purified water or mains unsoftened water if you have a water softener. They are not designed for boiling water.
With Tee Pieces, the one that is sticking out of the fitting is always the "odd" fitting size. EG 1/2' x 1/2" x 3/8" Tee Push Fitting, the one that is not inline is the 3/8" size.
We have created a video that is on our YouTube channel to demonstrate changing the filters on a RO system. Simply click here to view: How to change filters on a RO system
To find out what filters are used on your system, please check your invoice from when you bought your system to find the system model number, then check the graphic below to find out the filters used on your system:
The mains piercing needle valve is suitable for use with 9 or 15mm copper pipe and is clamped to the pipe using the threaded rod at the base and the applicable pipe holder. Once clamped in position the RO pipe can be fitted to the valve using the threaded outlet having first made sure that the white olive is fitted before tightening up the nut. To pierce the supply, turn the T bar to screw the needle through the wall of pipe as far as it will go. The pipe is now pierced and by unscrewing the T bar the water will be allowed to flow to the RO unit.
The waste water pipe is a permanent installation and should be used with the drain saddle supplied. To fit the drain saddle first find a suitable section of waste pipe under a sink that is not flooded with water and drains easily away. Position the waste saddle and mark the pipe before drilling a 6mm hole. Fit and tighten the saddle in position remembering to fit the foam seal and then insert and tighten the end of the waste pipe into the drain. The wastewater will contain an increased concentration of contaminants, which should pass directly to drain or be collected for use in processes that do not require pure water, e.g. Watering the garden - not suitable for drinking water.
The handle on the valve should be inline/parallel with the pipe as shown in the picture below. This will allow the water to enter and exit the tank.
The thumb screw tap needs to be down (closed) to produce pure water:
Blue tap needs to have the handle to be 90 degrees to the pipe (closed) to produce pure water.
Usually this would be installed under the sink so it can be connected to a drinking tap on the kitchen sink.
As long as the system is installed within a reasonable distance from a mains water supply, this can be installed in a garage/shed or even a van.
As long as the system is installed within a reasonable distance from a mains water supply, this can be installed outside or garage/shed near a water supply.
