Upon installation of two new 17.5 inch seat height toilets in our house, I changed out the drain valve to a new one that sits 3 inches closer to the bottom of the tank. And put in new adjustable fill valves which allow three additional inches of fill depth in the tank.
Those bitches will take the Peterbuilt AND the 53 foot trailer. No 2'nd flushes required. I don't think it even costs a penny to pump the water for a flush.
Oh, the low flow restrictors in the faucets and showers are removable. My daughter comes over and marvels at the flow rate in our kitchen sink.
