I have no idea what's in a 6-way shock pack from H-D or how much. That's the problem. But if you must use that instead of bleach, be sure to dissolve it completely in 5 gallon bucket of water first. In fact, dilute the bleach the same way so it distributes better. It's just much easier to get the right amount with bleach.
As for the plunger: unless it's a rubber one, and has the shape of the old-fashioned plungers, rather than the newer, more effective ones (like the black rubber ones), you run the risk of damaging the liner and it not working. The plastic ones are definitely no good. Remember: You want to create a suction on a flat surface and you don't want to damage that surface. Spend the $3-$5 on the rubber one.
Good luck!
