7.3 Cleaning the pump hose
The inside of the pump hose can be easily cleaned by
rinsing the pump with clean water. If a cleaning fluid is
added to the water, check if the hose liner material is
resistant to it. Also check if the pump hose can resist
the cleaning temperature. Special cleaning balls are
also available. Contact your Bredel representative for
more details.
