  • The Primary Check Valve Filter is normally replaced every 12 months. It does not generally need to since it is a 10 Micron filter which is designed to protect the Primary Check Valves. In the event that it may prematurely restrict solvent flow, the solvent flow will be compromised and will effect the flow rate, which will show up promptly in the baseline, but this is not a common occurrence.
