Drench's concealed cistern is a brilliant piece of kit. Not only is it remarkably affordable compared to some of the inordinately expensive concealed cisterns from the big brands that are on the market, but it is exceptionally reliable - so much so that the incident rate that we record against every item we sell is lower than any other concealed cistern we've ever sold!The Universal cistern allows either top or front access. Essentially, what this means is you can get at the working parts of the cistern either from the top (for example if you mount it in fitted furniture and remove the worktop) or from the front (for example if your access point is a fitters panel in the furniture.)It has a dual flush button for a full flush (6 litres) or a water-saving half flush (3 litres.) The button itself is on a hydraulic cable, so it can be moved and mounted in a convenient location.
