Right now, the graywater line is plumbed directly to the regular toilet water in line.
That means the regular fill mechanism works exactly the way it normally does.
I plan to still add an extra shut-off valve and T so that I can reach behind the toilet to switch from graywater to drinking water. I want this flexibility for when I run out of graywater or otherwise might need to troubleshoot the system.
I don't know if there will be any further wear on the tank fill valve from graywater compared to drinking water.
I had a filter on the system, but the lint gunked it up after only one load of laundry! I am going to put a more course filter in place of the original filter.
