Lift the pump out of the tank. Place the pump on the ground, taking care to not break or stress the pump suction piping assembly.
Unscrew pump strainer from the end of the pump suction piping assembly.
Remove the retaining clip from the pump end-cover. Butterfly check (Technocheck) valve assembly can be pulled out. There will be slight resistance due to friction of the o-ring.
Pick up new end cover/male fitting assembly and new o-ring. Insert o-ring inside of end cover. Using rubber mallet, gently tap new end cover into place. Replace retaining clip.
