A later innovation, the floatless fill valve, designed for low-profile, low-flow toilet tanks, uses a pressure-sensing diaphragm mechanism instead of a float to control the inlet valve. [4] Delay valves, which delay the filling until the level has dropped to a low level, avert short-cycling of the water supply.

When the toilet paper becomes saturated, it is removed and replaced with a fresh roll.
This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is ...
