Converting normal water supply to tankless toilet

Hi all,
Is it easy to convert a normal water supply line to a pressure assist tankless toilet? How do you do it? Will it have enough pressure to flush?
Thanks,
Phil

If you plan on using a Flushometer style, you will need a 1" line to the toilet. The rest of the house will need to be up sized too.
The reason a 1/2" line works for a tank style toilet is the water stored and ready to drop in the tank.

Thanks Terry!
I will check to see if there is a 1 " supply line - it is in a business.
