I am 90% sure there is not blockage as the water level always stays the same, even after flushing the Drains with lods of water.
Ours was the same, the drain round the back looked fine, but something was blocked somewhere. Cleaning with buckets of water for a while, nothing. Sorted itself out after a week, probably a dead rat in the drain or something.
