I'm not a professional plumber but I've replaced many wax rings before. The toilet worked perfectly fine before until I noticed a little leak at bottom of toilet. I replaced the worn out wax ring.
There are no more leaks but this time the water overflows and just won't have that swirling flush! Very slooow drain. There's no blockage, no leaks and I even replaced the wax ring a second time, just in case. I'm stumped! Just can't figure it out. Plunging, snaking and chemicals won't flush the toilet.
