Prolonging the life of pump valves
Before first use, you need to sterilise valves, but you don't need to sterilise on a daily basis unless profession advice. 
Washing valves with warm, soapy water should be enough to cleam them.
Avoid washing valve in the dishwasher, frequent sterilisation, stream-sterilising in the microwae. 
Grab its tag gently down from the connector.
 
We recommend replacing this part every 2-4 weeks for frequent pumping or every 2 months for daily pumping to maintain the optimal effectiveness of your pump.
