Replacing O-rings
If leaks are detected around the O-rings, new rings should be installed. To install, insert
a pencil in the O-ring, pry out and replace with a new ring. It is not necessary to remove
the wall plate.
NOTE: To facilitate installation, wet or moisten the new ring when installing. This wetting
acts as a lubricant, allowing the ring to slide in more easily.
