ABSTRACT:
An adapter for mounting a diaphragm-type push button control, for remote actuation of a water metering valve, to countertops or lavatories of various thicknesses and through openings having various diameters has a circular cap portion with a diameter greater than the largest opening diameter and a threaded cylindrical shank portion concentric with the cap portion. The diameter of the shank portion is slightly less than the diameter of the smallest opening and the length of the shank is greater than the greatest thickness of the countertops or lavatories. A faucet washer and nut having a diameter greater than the largest opening are threaded onto the shank. An end of the shank has a pipe thread to permit attachment of the push button control thereto. A cylindrical push rod is disposed through a concentric opening in the cap and shank portions with a push button portion thereof extending from a first end and from the cap portion. A second end rests on the diaphragm of the push button control. Depressing the push button portion thereby actuates the diaphragm to produce a pulse of air.
