I have 2 toilets on the same vent pipe. The main floor toilet is very sluggish and will only flush liquids and very little paper as the bowl fills almost completely before draining slowly. After using a 3 foot auger to check for blockages my next thought was a blocked vent pipe but the basement toilet flushes completely without any issues and there is no grugling from any other drains. The drain pipe from main floor is 3 inch copper and ties into the stack with a 90 and T. From the basement I can hear the water trickling into the 90 so i assumed it wasn't blocked. Any advice?

Since it is an 'upstairs' toilet, the problem is NOT a "vent" or any other system problem. It is a problem in the toilet. There is a big difference between HAVING a closet auger, and knowing HOW to use it properly.

Given that I work have worked at an elementary school for several year and am proficient at using an auger. Any other suggestions.

Either there is something in the bowl the auger is NOT removing, or the openings in the bowl are not "open". MANY, MANY times I have come in after someone has been augering the bowl, and removed the problem with my auger.

Could someone (child?) have flushed a toy or other item that is stuck in the toilet trap and partially blocking it? Depending on the size of your auger tip it may be working past the blockage but not moving it. You may need to pull the toilet and look up thru the bottom opening. If you do that you will also have the opportunity to check the closet bend (toilet drain below the floor). You can pour a big bucket of water into the floor drain hole and see that it goes down quickly, that will be evidence that your problem is likely in the toilet trap. The trap in a toilet base is much more bent than a normal pipe trap, it is engineered that way so all the water in the bowl and the trap is siphoned out when flushing, then it refills as the tank refills. Plastic toys and other objects can get stuck in that severe bend in a way that allows water to pass but not solids very well.

The home had 5 little ones in it prior to our purchace. The flange bolts are rusted and need replaced anyway and I already planned on replacing them. I will pull the toilet this evening and I'm sure I will find the peoblem. I will report back later with the results. Thanks guys.
