We're going in the wrong direction with this... O.K. The issue is not going to be related to higher or lower internal traps... simply doesn't make sense that you have gotten the only 3 toilets that are an issue like this...
something else is up.
You bought/installed three toilets and none of them will fill the
toilet bowl water level to
above the seal of the internal trap so you are getting sewer gasses into the home all the time.. right?
I need to be clear on this fact... or is it that water disappears from the bowl over time?
You also had 3 plumbers that could not help you by making any adjustments at the tank of the toilet... right? I'm wondering if any of them lifted the toilet and checked the drain pipe? How about the drain/vent system? Is there a bathroom above this toilet? Also, I just don't get
any plumber walking away without discovering an answer to something like this!
What happens if you fill the toilet bowl to above the internal trap by adding a gallon of water.. does the water disappear to below the trap over time? This could indicate that the bowl is getting siphoned by something or that there is a failure in the casting of the toilet bowl.
Sounds to me like the issue is with the plumbing system or with the toilet installation as Tom suggested.
Finally, were all 3 toilets of the same design? If so... what name brand? If so, you may want to go with another brand. I recommend
toto toilets,
american-standard and
kohler toilets (in that order). They each have some very affordable, good flushing toilets... I guarantee it! You can find toto toilets online or at a local plumbing supply house. Home depot and Lowe's carry kohler and american-standard.
Answer my questions and then we can give a final opinion...O.K.?
Thanks... MARK
