1 An escutcheon plate is the disc around a plumbing pipe at the wall penetration that seals the wall opening. The photo above shows a chrome escutcheon plate where the water supply pipe for a toilet enters the wall. You will also find escutcheon plates at the pipe penetrations under sinks and behind water heaters.
Escutcheons are attached either with screws or caulking. To remove a escutcheon attached with screws, simply take a screwdriver and unscrew from the wall. To remove one that is attached with caulking, take a plastic putty knife and gently cut through the caulking to lift the plate away from the wall.It is important to always use a putty knife when removing a escutcheon attached by caulking.o remove one that is attached with caulking, take a plastic putty knife and gently cut through the caulking to lift the plate away from the wall.
