Almost every type of drain cleaner specifies that they should NOT be used in a toilet. Why is that?
Is it because they feel there is too much standing water in the toilet due to the size of the trap?
Or does the cleaner have an adverse effect on the wax seal used for the toilet bowl?
The reason I ask is I had a poorly flushing toilet and plunging it did not improve the situation. I tried a snake but the trap of the toilet and the direction of the drain pipe underneath it made the snake ineffective. I ended up removing the toilet and used a snake. What I discovered is the toilet met up with the tub drain pipe, and I know this from the hair I pulled from the piping with the snake and the direction the piping went.
The toilet flushes, but my guess is there is still some hair from the tub that is restricting the flow. So my question is: If I were to remove the water in the toilet and put some drain cleaner into the toilet after the trap, would that cause any unforeseen problems?
I have already put some cleaner into the tub drain, and a snake will not go into this drain due to the drain hardware of the tub. Thanks.
