Cause:
The lack of chlorine in tank or bore water provides a more favourable environment in which bacteria can develop.
This bacteria finds an ideal environment along the inner hose wall.
This issue is not widespread -It is only prevalent in a small percentage of people using tank or bore water.
Outcome:
Consequently, after a period of non-use the bacteria builds up and when the hose is turned on the bacteria is flushed out.
This bacteria can be strong in smell and appear in the form of a milky white discharge.
This usually clears up after using the hose after a minute or so of water use.
Prevention:
Once you have stopped using the classic hose reel, ensure you turn the tap off and release any excess water in the hose so it's not sitting in therefore a period of time.
Note: This issue does not occur with the Evolve hose reel.
