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 they 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.
