Q. Can Drain King be used to unclog a toilet?

Q. How far will a Drain King clear a clogged pipe?
A. Drain King will clear most clogs up to 1000 feet. It will not clear roots.
Q. Do I have to plug all other outlets (vents)?
A. Drain King should be inserted past any potential areas where water might vent out. If not possible, simply close or plug potential vents.
Q. Could the Drain King possibly slide out of the pipe while in use?
A. NO. Drain King has an automatic lock-in-valve that locks the unit in place. If the clog will not give way immediately, the back pressure will cause the lock-in-valve to close while keeping water pressure on the clog until it gives way.
Q. Does water temperature have bearing on Drain King’s performance?
A. Water temperature has no bearing. We do recommend cold water for increased life of the product.
