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. |
|
| |
+ 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. |
