This kit contains the following items:

Option 1: This Kit contains 4 O-rings (No duckbill valve) for your Flushmate.

Option 2: This Kit contains 4 O-rings PLUS the duckbill valve for your Flushmate.

We always recommend to purchase the kit with the duckbill valve unless your are sure that the duckbill valve does not need replacing.  The duckbill valve as well as the o-rings are all critical elements of a properly functioning Flushmate.

If your Flushmate toilet has week flushes, takes longer to fill, makes noises (running water), or you notice water or drips when you open the tank lid, you need this kit. Precision Fit USA brand... buy America !
