FIX-A-LOO® have two inlet valves, so depending on the model, the cap/nut may be screwed onto the top of the valve (A) or on the side of the valve (B)

Type A

With valve type A, pop off the blue top and remove the arm off the float cup adjusting rod. Then twist the arm counter clockwise to remove retaining cap. Replace the inlet valve headseal.

Type B

With valve type B, remove the arm from the float cup adjusting rod by pushing the rod away. Unscrew inlet valve headseal nut and carefully slide it down the arm. You want to leave the arm attached to the retaining cap. Twist and remove retaining cap to replace the inlet valve headseal.

Rinse the valve and the new inlet valve headseal before assembling it.
