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.
The diaphragm technology allows the flush valve to open and let water into the bowl. A main cylinder valve operates up and down. A groove in this cylinder allows water from the main supply to flow through when it is in a mid position. The valve is shut off at both its top and bottom positions.
The ballcock or float valve is often used to regulate the filling of a tank or cistern. When the fluid level drops, the float descends, levering the valve opening and allowing more fluid to enter. Once the float reaches the 'full' position, the arm presses the valve shut again. Tank fill valves are found in all tank-style toilets. The valves ...
The visible water surface in a toilet is the top of the trap's water seal. Each fixture drain, with exceptions, must be vented so that negative air pressure in the drain cannot siphon the trap dry, to prevent positive air pressure in the sewer from forcing gases past the water seal, and to prevent explosive sewer gas buildup.
This pressure wave can cause major problems, from noise and vibration to pipe rupture or collapse. It is possible to reduce the effects of the water hammer pulses with accumulators, expansion tanks, surge tanks, blowoff valves, and other features. The effects can be avoided by ensuring that no valves will close too quickly with significant flow ...
