Flushing cistern: Compatible with Valsir front or top operated concealed cisterms
Pro-tip: When deciding on whether to have top or front operated flushiing cisterns. Do take into consideration the position of the toilet in respect of the basin area. Most top operated cisterns have a finished height of approximately 800 to 850mm. This would be a perfect flush to basin counters for undermount/semi-recessed basins.
Also, ensure that there is always maintenance access created.
Pro-tip: If you are re-doing your entire bathroom including hacking of exisitng tiles, it will be possible to re-locate your water supply position. Be sure to provide the technical data sheet to your contractor and they will be able to assist you better.
