I have two toilets that do not want to flush most of the time. They
share a wall so that they are back-to-back and I am sure they share a
common pipe. The trouble started without warning yesterday and
continues to today. The sinks and tubs in the same bathrooms have not
been slow, nor are there any gurgling noises, etc. The odd thing is
the toilets flush when I add dishwashing detergent to the bowl water.
Without the detergent, they do not flush. I learned of that
"trick" on other websites. I had just added some blue automatic
toilet cleaner blocks to each toilet. I removed them, but some
residual remains. It was suggested to me to try running a water hose
with the water running down the vent pipe. I have not tried that yet
simply because I have no way of getting on the roof. For what it's
worth, the toilets are located on the opposite end of the house from
the vent pipe. I have tried repeated plunging and I had put RidX in
I'm having trouble believing the dishwashing soap helps. It sounds too
coincedental for it to be separate problems, but it's possible. Do the
toilets ever actually overflow, or do they just not flush right? What
happens if they're flushed simultaneously?
What a plumber would do, if he couldn't figure out something easier, would
be to pull one of the toilets, and what what happens when the other is
flushed. Can you supply any more details?
Thanks for the reply Mike, but I have since solved the problem. The
problem was the blue block cleaners. I read on various websites after
posting my problem that the blue blocks can thicken the water and/or
clog the openings under the rim of the bowl. Both prevent the suction
needed to flush from getting started. I'm not sure if either is
correct, but I performed the detergent "experiment" repeatedly and
adding the detergent always did the trick. I would guess it has to do
with lowering the surface tension of the water. I removed the blue
blocks and the toilets will flush by themselves, albeit not as good as
they do with the detergent.
I thought you meant you dumped the detergent in the bowl. For future
reference, a coat hanger is the perfect diameter for reaming out the holes.
When you wrote, it sounded like both toilets were malfunctioning at the
same time. I, of course, would have diagnosed the problem immediately had I
