This is wrong. Some toilets use the normal “sink” plunger because the exit opening is too large for the “toilet” marked style. You get either or whatever fits your toilet. It’s not specifically for sink only.
"You get either or whatever fits your toilet. It’s not specifically for sink only."
Incorrect.
The cup plunger is designed to fit over drains on flat surfaces, while flanged plungers are designed to fit inside the outtake valves of toilets.
"Some toilets use the normal “sink” plunger because the exit opening is too large for the “toilet” marked style".
This is also wrong because:
The flange is as wide as a cup plunger for sinks anyway, so a sink plunger won't work if a toilet outtake is too wide for a toilet plunger, and
the toilet plunger is made to fit inside the outtake of the toilet, not over the mouth of the drain like a cup plunger.
they are completely different designs and have different use-cases that you will only give you and others more trouble and mess for by not knowing and spreading misinformation.
I am not wrong. There are toilet designs where the flange style literally doesn’t cover the exit chute. I have one. I have to use a “sink” style type. The flange style is small and does not form any type of seal due to the shape and size. It’s literally impossible that it is the correct solution. Everything I said is 100% correct.
"There are toilet designs where the flange style literally doesn’t cover the exit chute."
The flange is not designed to cover the exit chute, but rather to fit inside the outtake.
This is also apparently due to your specifically atypical plunger.
"The flange style is small and does not form any type of seal due to the shape and size"
since flange and cup plungers are the same diameter, you are clearly having an anomalous problem that you should not be drawing broad conclusions from.
cup plungers and flange plungers are specifically designed to address different problems, to be used in different manners(the cup covers a uniform drain on a flat surface while the flange creates a seal within the sloped and curved toilet outtake by fitting inside the outtake) and are not interchangeable.
Your premises are flawed and your conclusions are incorrect.
Literally don’t give a shit what you say. I am not wrong. On this specific toilet, the flange style literally doesn’t seal and CANNOT perform a push / pull to unclog a drain due to the exit profile and shaping.
You are not right no matter how smart you think you are.
I think you are failing to understand the design / curvature / multiple radius features of the exit point and that the flange style literally cannot form any remotely close to passable seal to do its job. Idk what to tell you but your not right no matter how you think you can phrase it.
