Troubleshooting

Water flow is frequently interrupted by air
Purge any residual air from the system:
1.
Turn the system housing upside down.
2.
Turn on the filtered water faucet.
3.
Allow water to flow for one minute.
4.
Turn off the filtered water faucet.
Odor – rotten eggs, no discoloration on the filter
A rotten egg odor is a sign that H2S (hydrogen sulfide) gas is present in your water source.
If hydrogen sulfide gas is present in your water source, it is recommended that you
rotate DWS usage between 2 filter cartridges. When the DWS emits the rotten egg smell,
remove the filter and allow it to dry upside down to allow the gas to dissipate (the filter
can be reused once dry). Use the second filter in the unit while the first filter is drying.
Odor – rotten eggs, with discoloration on the filter
A rotten egg odor is a sign that H2S (hydrogen sulfide) is present in your water source.
Filter discoloration can determine the source:
•
orange/brownish colors – iron
•
blackish colors – manganese
•
slimy/blotchy colors – decaying organisms
When hydrogen sulfide comes from a source that discolors the filter cartridge and
creates a strong rotten egg odor, the only recommended solution is to change the
filter cartridge.
Color – milky color in the water
Milky color in the water is typically caused by air bubbles in the water. Higher than
normal water pressure through the DWS can create these small air bubbles, but they
do not affect system performance.
For countertop systems, turn on the water and engage the diverter valve while
slightly reducing the water flow. Less water pressure through the system can prevent
air bubbles from forming.
Color – black color in the water
Black color in the water is typically caused by residual carbon dust from the filter.
Allow water to run through the DWS for approximately 30 minutes to flush the filter.
Residual carbon dust may initially color the water black.
Flow rate – the water flow rate is slow
The filter is designed to restrict its flow rate when clogged with particulates or other
solid contaminants.
