Figure 5-3.Service sink (slop sink).
After the tank is firmly attached to the bowl,
connect the water supply pipe to the tank inlet with a
riser tube, as shown in figure 5-11. The jiffy connector
used here is the same as the connector used to connect
the water supply to the faucets of a lavatory.
Flushometer valves are used in place of a tank-type
valve in some applications. When a flush valve is used,
no tank to hold the flushing mechanism or water is
required. Flush valves operate by diaphragm or piston
Flush valves require less water volume per flush
than a tank-type valve, provide quicker multiple
flushing capability, and lower maintenance costs in
commercial applications; however, they are noisier
than tank-type valves, initially cost more than a tank-
type valve, and require a higher operating pressure
than tank-type valves. Basically, the flush valve is
suited more for the commercial or industrial
application, and the flush tank is used in small
buildings or single family dwellings.
