1. Is the Line to the toilet a standard Plastic line or a flexible rubber/vinyl line?
2. Does the line if flexible go into a floor or wall opening? That line is usually either "t"d off or runs behind the wall or floor to its cold water connection point. IF flexible it could be bent/crimped inside the wall causing restriction.
3. Another cause is the toilet water line inlet has debris/calcium build up restricting the normal flow of water. To fix this you pull the toilet(easy to do) and look at the inlet and blow out if you see debris. Doug
The line to the toilet is rigid as it comes out of the wall, and then it connects to flexible vinyl line that leads directly into the toilet. If that makes any sense. So since the flexible line is only outside the wall, it can’t be crimped in there, but thank you for mentioning that. My husband pulled the toilet (because I complained about an odor) and discovered the toilet was not installed correctly, so he has just replaced the flange and gasket, and will be replacing the inlet valve tomorrow, so that should take care of any of those elements.
Interesting to note that he ran some water into the bathroom sink and saw ripples and movement in the black tank water. So we believe the bathroom sink is draining into the black tank even though people have told us it drains into the grey tank. Yet, we don’t get the noise when we run the sink, so we are not sure if the idea that it’s a blocked vent is valid, but we’ll be checking it.
