<p>The toiler flushing cistern has standpipe overflow cap for indirect water draining by vacuum from high level flushing cistern. The flushing water is metered by relatively simple means for water saving purposes. The overflow cap (f) has venting value (1) for regulating water flow quantity. This valve is opened by the water supply float valve (i) by means of the level on which it is suspended at a given lever arm length. This stops the water outflow at required water level. Full draining is ensured by continuing the actuation of the lever system e, d when water is drained through bottom valve (b).</p> |
