My Eco Drake (classic) has moderately good bowl rinse in the front of the toilet. But toward the back of the toilet (i.e. closest to tank), there is little bowl rinse, since day one. The toilet is installed reasonably level, but little water come out from perhaps 10 o'clock to 2 o'clock. Due to the water saving design, the water only comes out in force for a second before the flapper closes, so the bowl rinse performance is important.
Is this normal? Are the rinse ports designed to be smaller in the rear of the bowl, perhaps to encourage water to travel all the way to the front?
