OK - never heard of siphonic aspirators, until the recent post. We have two toilets, of exactly the same design, same flush tank, same fill valve ect.. Both have always had a poor flush - customary method, is to have a jug of water to hand, press the handle, and add the jug of water, as the flush gets under way.
Toilets bowls are both the same design, the upstairs one exits sideways via a plastic 90 deg adaptor, then rigid pipe through the wall. The downstairs one, discharges straight down, and under the concrete floor. The cistern is the usual low level, linked to the bowl via a flush pipe, with a 90 deg bend, to enter the rear of the bowl. In cistern, the siphon is a Dudley 88 dual flush, which sometimes works to give a short flush, if the handle is held down - mostly it doesn't.
The level in the bowl doesn't rise, doesn't fall, even during a flush. Our upstairs stack, is open vented, the downstairs one is unvented.
I fitted the Dudley 88's, as replacements for the earlier units, after one of the earlier units gave issues after many years of use. I have no idea what the earlier items were, but both systems gave poor results. Both cisterns refill to maximum capacity when flushed. So, what is/does a siphonic aspirator do? Should I be fitting one to my toilets?
