Can anyone tell me whether there is a way to adjust the water level in the bowl of the Toto Drake? Just had two installed and the water level seems very low. Thanks.
first make sure the black rubber tube is pointed into the white overflow tube.
This is the "make up" water for the bowl.
The water in the bowl is determined by the upper curve of the trapway.
It acts like a dam. The water won't get higher than that.
1.6 gallon toilets do have less water than bowls for 3.5 and 5.0
