I have a toilet installed w/o a vent pipe. Originally a siphon toilet wouldn't flush very well (especially solids). I found a toilet with a closed internal tank that seems to force things down using some pressure and this works much better (usually 2 maybe 3 flushes to get all the solids down but at least they go down). However about every other time after flushing the water in the bowl still gets sucked out until you hear a gurgling sound as air vents into the main pipe through the bowl.
Do they make a toilet with an external vent attachment (which I could then tie into the vent stack from the sink) or a 'ventless' toilet to allow air in but keep the smell out? If so where do I find/order? I know there must be slight pressure in the main line which is preventing a normal siphon toilet from flushing and causing the water to get sucked out 5-10 seconds after most flushes.
I know the proper thing is to bust up the floor but that would be difficult for various reasons. Local plumbers have been no help and could not even identify the original problem.
