This is the worst toilet I have ever seen. I put 3 pieces of toilet paper in and flushed 12 times. Toilet paper has not gone anywhere. It's like dumping a half rain barrel of water down a drain with no pressure. It will be in my truck tomorrow on it's way to the landfill. I thought I was saving energy, all I did was waste $90 some dollars. Now I have to go buy a real toilet. Nice design, Pegasus. JUNK !!!!
