I'm replacing the toilet in my bathroom and ran into a little problem. I purchased a toilet that is for a 12 inch from the back wall to the center of the flange. I put a compression stop valve on the end of the stub-out so I can turn the water on or off :confused: when I need to work in bathroom. I go to see how the new toilet fits when the holes for the toilet are at the center of the flange and this is when I start having problems. It turns out that I need to move the toilet back more by at least 1 inch so it is in the center of the flange. This would be easy but the shutoff valve is actually hitting the back of the toilet. It turns out that who ever roughed in the stub out for the supply, put it through the wall and it lines up exactly with the center of the flange. The 1 inch that I need to move the toilet back so it lines up with the bolts in the center of the flange I cannot do because the handle of the stop valve hits the back of the toilet.

I tried taking off the stop valve and adding a 90 degree compression elbow and then adding a valve but its still not enough room. The half inch copper stub out sticks out of the back wall only 1.5 inches. I was thinking about cutting this down to maybe 1 inch but I donot know if this will be enough to help me. I cannot believe the they stubbed out the supply right in line with the toilet. Any help will be greatly appreciated.

If I were faced with this I would cut the stub-out back to 1" and solder on a 1/2" elbo to the stub-out aslong with a 5" piece of 1/2" copper I would then turn up a 1/2" street elll and attach a 1/2 X 1/4" compression straight stop,(see image) and supply the toilet in the usual way. Good luck Tom
