: We have a constant battle in my house to keep the three toilets unplugged. I know the clog is biological.... Usually plunging gets things moving, but currently we have two toilets plugged. Plunging isn't working. Should we try lye or some other chemical to help break up the clog? Is there some sort of enzyme or chemical we could use as needed to keep things moving? We are on city sewer, but is there something we could use that is used on septic systems?
Chemical drain cleaners do not work. The toilets should be hand augered by a licensed plumber to break up any clogs. The main drain should also be inspected for proper operation. The toilets may even need to be adjusted or rebuilt to insure a good strong flush.
Good Luck. e-plumber
