I have a toilet which drains out quite slowly and water rises to the brim when the flush is exercised.
I have already used the plunger multiple times to try to see if it makes a difference, but it has not helped much. The water level still takes about 30 minutes to go low after a flush. I am clueless at this point.
Is there anything else I can try? Is there a 'draino' equivalent for toilets?
