My toilet won't flush completely. When you try to flush the toilet it fills the bowl almost to the verge of overflowing. Both toilets are doing this... Any help at all?? It would be so greatly appreciated.

Are the toilets back to back. If not, is there any other problems with other fixtures draining slowly or gurgling when the toilets are flushed.

Answer MGD questions. If both toilets are on the same line then you have a partial blockage downstream from them. You can pull a toilet and snake from there or snake from a lavatory roof vent. Good luck. Tom
