Toilet cistern - Siphon question

[Rollerball]

My toilet cistern has a siphon very much like the following (picture below - the only difference is that mine doesn't have that elongated blue 'slider' on the side) but otherwise it's a Derwent MacDee Metro 3-Part Siphon.

Looking at the C-Link, the lower loop attaching to the black shaft of the piston (the upper loop attaching to the lever arm that is attached to the toilet handle) - that black shaft of the piston is visible inside a raised molded plastic surround (which I'll call a 'well'). Should the water level be slightly above the rim of that 'well'? Or should the 'well' be dry?

Thanks

Show us a picture looking into your cistern.

The height of where the water level should be will be on the inside back face of the cistern.

So, I'm referring to the 'well' where you can see the black top of the piston shaft that in this photo can be seen roughly underneath the black lever arm. Should the water be in the 'well' or should it be dry(ish)?

It shouldn't make any difference. See post #3 re the intended water level.

Normally the cistern water level is well above the "well" - at the mark on the cistern wall somewhere or, failing that, about 1" below the overflow level. The well has no significance with regard to the water level.
