>flushing needs more water making it an eco thing to install something different
fun fact, in europe, semi-older houses were often built with DN110 HT because toilets often had upto a 9L flushing cistern. In the 2000-2010s, people replaced their toilets to be more ecofriendly and adjusted the cistern to 4.5-6L of water, which results in the water level not being high enough for shit to actually being flushed out the sewage. Newer houses that were built around that time don't have that problem because their sewage pipes have been adjusted to the pipe diameter DN80.
