Hello Forum,
I renovated my bathrooms 3 years ago and replaced the American Standard toilets that were here ( dont know whether they were 1.6 or 2.5 or higher GPF toilets). But I replaced them with Kohler toilets. The Kohler toilets siphoned water from each other so I thought it was the flushing system on the Kohlers. So I went back to the American Standard toilets and they still did the same thing. Not knowing the GPF, after talking to every plumber in town I learned that the GPF on the toilets they removed could have been 2.5 GPF and they installed 1.28 GPF toilets, that that could be the problem going on with the siphoning.
However, I have had no resolve for this issue. The toilets flush fine, its just that if I constantly flush the one toilet the other back to back toilet's water level decreases until there is maybe a cup of water in the other toilet. When I flush the low water toilet, then it returns to the proper water level.
The recommendation was to replace the double sanitary t with a double combo. The problem with that option is that there isn't enough crawl space to do that underneath the house and to really make something like that happen would cost upwards of $2500. Ugggghhhh all that just for swapping out the toilets!
So after 3 yrs and asking every plumber I could find i thought well maybe I can find the old GPF toilets that were in here initially because the house was built in 1994 here in Oregon. I couldn't find any. I'm at my wit's end! I can't rent this home with dysfunctional toilets.
