The pipe that connects the toilet reservoir to the toilet seat is leaking at the bit that joins the reservoir and the downpipe
I am thinking the blue detergent bar I put in the reservoir may have something to do with it
Can I just undo it and put plumber tape and rescrew or shall I not try?
Any help is appreciated!
edit: pix is view looking up from below
the pipe is coming out of the bottom of the reservoir
leak is from the screwy thing you can see
