I have a one piece low profile American Standard toilet bowl. Out of no where, the flush has turned to a very slow sluggish flush today. I have checked the Rim Jets and they look clear. I have used a plunger several times to no avail, I have checked the water level, flap, and overflow tube and they all look fine. I tried Drano and pouring Hot water from a bucket to maximize the flush and NOTHING seems to work. The water in the bowl drains slowly and ends with a gurgle. What could it be? I have read a few of the older posts on here and it looks like I may be experiencing a vent problem? Or is it a drainage problem? :confused:

Are you missing anything? Do you have a maid that cleans the toilets? Many times in a situation like this a maid has broken a bowl brush while cleaning during a flush and it is stuck inside the bowl.
