I'm about to install a toilet in my basement and the closet flange is uneven. The floor is concrete. One side of the flange is above grade and the otherside sits approx 1/4" below. How can I solve this so that my toilet does not leak?

Hi Jchoo...

I'd purchase an EXTRA THICK reinforced wax gasket and extra long closet bolts for this job... should be all you need!
