Q: I have one toilet in my house that is flushing very weakly. The other toilets are working fine, so I don’t think this is a problem with the drainpipe. What could it be?

A: Toilets flush properly when the water from the tank flows freely into the bowl and can then easily exit the bowl into the sewer. If the flow at either location is reduced, this condition will occur. Sometimes a submerged mirror will reveal an obstruction, but most often it is necessary to use a toilet snake. A minor clog in the toilet trap can easily be removed with a snake. The other possible cause for the weak flushing action involves the water holes under the rim of the toilet bowl. Over time, these holes can clog with calcium, restricting flow.
