  • How do I know which CLV Strainer to purchase for my Monitor 441?

    The best way is to take yours out and look at it to be sure you are ordering the correct part.  

    The Monitor 441's that were produced up until 1998 are different than the ones produced 1999 and later.  Sometimes the older units have been updated with an Update Kit.   

    CLV Strainer Part # 6304:

    Fits the older Monitor 441 (Pre-1998). 

    If you have an older model and if you PRESS IN on the "reset" or "primer" button.

    CLV Strainer Part # 6470:

    Fits the newer Monitor 441 (Post-1999 and newer or updated older models) 

    If you have an newer or updated model and if you PRESS DOWN on the "reset" or "primer" button.

    If you are still not sure, please contact us for further assistance.
