I have a rear discharge toilet (Gerber) in an upstairs toilet above my kitchen in a home that is only 13 years old. (Not sure model but I found the following written inside the tank A-51 28-590). It is a 1.6GPF model. Due to the design of the house, the pipe in the wall behind the toilet is 6 feet long and is angled downward but only drops 18 inches (over the course of those 6 feet) before turning straight down in the wall.
It always requires a double flush (even with no solids) and sometimes that is insufficient.
The tank fills to the designated fill level. It empties in 10 seconds and appears to be emptying normally into the bowl. I have dismounted and checked the pipe behind the toilet and it is clear.
What is the reason for the poor flushing? Is it the design of the toilet? Is it the low angle of the pipe in the wall? What is the best solution?
Thanks for any help!
