Supply Line Clearance

I have two toilets to replace and have decided to use the Vespin II and/or the Drake II. My problem is the supply lines come through the cement floor and I can’t determine if the lines will clear the toilet bowel. On the first toilet, the line is 6in to the left of the drain centerline and 8in up on the wall. It is a 10 ½ in rough-in so I will need to use the Vespin II with a 10 in kit. If it will fit. That is if the Supply line will clear the back of the Vespin bowl. I hope someone can help with my problem.
The other toilet has the supply line that comes up through the cement floor. It is offset by 8in to the left from the centerline of the drain and 6in from the wall. Would this clear the Vespin II or the Drake II? The rough-in is 14 in, so I could use the 12 in or 14in kit on the Vespin II if that would give enough room. I am open to the using the Drake II on this if needed.
One more thing, the house was built in 1993 so it is plumbed with the gray poly pipe; I think it referred to as PB. This could be a problem with causing a leak.
Thanks

I will address the last item first. If I, or any of my customers, had a 1993 house with PB, they would have had a leak prior to 2006 while they were still covered by the class action suit. The width of the toilet will determine whether the supply lines are a problem, and that has NOTHING to do with whether it is 10", 12", or 14".

It sounds like I might not have a problem with the pipe in my house, that would be nice. About the supply lines, would anyone know if the one that I have that comes straight up out of the cement slab will work with a Vespin II or would the base be to wide. The line comes out of the floor 6 inches from the wall and 8 inches from the centerline of the toilet drain.

The Vespin II will work with the water line at 5.5" from the left of center if it's on the wall.

The supply on the floor, at 8" ti the left may work with the Vespin II.

The Drake II works with either.

Thanks for the information. This is the only forum that I know of where you can get this kind of help.

Please disregard, started new thread.
