Hey everyone.
I have a toilet without a siphon jet. A couple of weeks ago there was some material in the bowl that did not go down - it got stuck somewhere in the siphon. I plunged it, eventually I got to a point where a toilet flush would fill the bowl, and the siphon whirlpool would never really start to much of a degree, but the bowl would start emptying.
Without a true siphon in action, it doesn't completely empty the bowl of water. However, some water / material will make it out of the bowl, although it might take a few flushes to clear everything because of the incomplete siphon.
Ok... The dumping of a pale of water into the tank does start a true siphon. But part of that might be the fact that when you dump water generally it goes in the center of the bowl, and that water velocity might be assisting with the siphon.
The bowl does fill rapidly and gets to about 1" below the bottom "lip" of the rim. It hovers there at its peak for a few seconds while the siphon "fizzles" and then slowly drains.
I'd rather not try the muriatic acid thing as I don't really believe that the filling is a problem. However the fact that I am still able to use the toilet and flush real waste (just with several flushes) suggests there is no "hard" constriction.
I'm thinking there is some very weak constriction on a side of the waste pipe somewhere, possibly in the toilet, possibly in the pipe... And it is causing a slight disturbance to the siphon, and hence it never gets started.
What do y'all think?
