Beerus, I was being tongue in cheek about it, and going with the whole "assault toilet" (assault weapon) theme.
Yes, low flow is the Federal standard (since the mid 90's), and anyplace you require a permit to change a toilet out you must use a low flow. However here I do not require a permit to replace a toilet, and I can use whatever size I want. To that end I can still, locally, buy a 3+ gallon toilet, and I can still install that toilet. The toilets in the house are all low flow, but the one in the garage is a high capacity model, and I just replaced it 5 or 6 years ago.
T!
