Just installed the Ultramax and have one concern. The spec sheet for the Ultramax specifies a water surface area of 10-1/4" X 8-1/4". My bowl fills to the size specified but , over the next 20 minutes the level drops 1/2" to a smaller water surface area of 9-1/2" X 7-1/2". It remains at that level for at least 12 hours.
Is this normal? Are there any remedies for the water level height in the bowl?
The bowl is level left/rt and back/frt.
