This Architectural Drawing is AutoCAD 2d drawing of a Side Section of WC wall. Tank: This is the back part of the toilet that holds the water used for flushing. It also houses the working toilet parts. Stop Valve: This controls the water supply to the toilet. It's usually located on the wall behind the toilet. There are really only two main toilet tank parts: The toilet flush valve, which lets water gush into the bowl during the flush, and the fill valve, which lets water refill the tank after the flush. When a toilet runs constantly or intermittently, one of these valves is usually at fault. For more details and infor mation download the drawing file.
