oneway toilet plunger   (+2, -3)  [vote for, against]
pushes water through instead of back and forth

Has flap valve at the top so repetitive plunging action results in a purely positive pressure instead of a fluctuating pressure.

But what the the fluctuating pressure is good? Sort of like rocking a car stuck in a rut.

Bone! [-] Sometimes you need that negative pressure to back out what ever can't be forced through. When you have massive amounts of tissue and waste matter wedged in the hole like a plug, sucking it back is about the only way it can be released.

The most restrictive area in a septic system is at the toilet. It's designed that way on purpose. Push it through and you're done with it.

Have you even had a toilet fill after it's clogged to the brim? That's when you need a one-way toilet plunger.

These are done. While not strictly a plunger, they are a method of using compressed air in singular, forward direction.

Even if its filled to the rim, sucking the obstruction outward will allow the rest of the water to freely flow down the drain.

Oh the negativity!

+ after seeing the DIY from notexactly, its simple to have it both ways (pun intended). If you want a regular back and forth plunger just close the valve. Open it, and you get a one way plunger.

Dave, propose it on Quirky!
