A rotatable knob for adjusting the temperature setting of a thermostat has a deformable tab that is permanently deformed upon rotational movement of the knob to a position that is indicative of a temperature setting greater than a predetermined optimum temperature setting. A deformed tab demonstrates that the knob was moved to a position for setting the thermostat at a temperature greater than the optimum temperature setting.

Thermostat

A one-piece casting for a water fountain bubbler having a cavity for a flow regulator cartridge, an inlet port, and inlet and outlet passages all integrally cast therein.

Bubbler

A valve assembly has a valve operting button with an outwardly extending button flange received in a cavity. Liquid entering the cavity floats the button to move the button flange into engagement with a surface, and this tends to seal the cavity and cause liquid pressure buildup therein. A venting path between the button flange & the surface it engages prevents sealing of the cavity, and prevents liquid pressure buildup therein.
