toilet flush question

[jack8]

Sorry if this is a daft question, have searched the net without really answering my question so here goes.
Just installed a button operated Fluidmaster dual flush valve. It's got two adjustments an up and down slider each for Full Flush and Mini Flush. OK no problem. I've got a low level system.

What I'm wondering is, is the increase/decrease of say the Full Flush a volume of water control or does it also affect the power of the flush? I suppose a bit more water would give a bit more power ?

The other thing, does the level of water in the cistern (assuming it's of an adequate level) affect the power of the flush? Or is the water level pretty neutral? Tthe gravity factor wouldn't be that great?


In short, what governs the power of the flush?

Appreciate a bit of input.

Cheers

The adjustment is just the amount of water used.

In short, what governs the power of the flush?

The height of the waterline. To see an improvement you'd have to raise the height of the cistern quite considerably.
