Push button Flush
Posted on
Modern WC systems can be too small to house a traditional ball float syphon flush mechanism. Therefore the inlet valve is either a modified diaphragm type wit a very short float arm, and miniature float, or an ingenious vertical valve with a float cup that fits round the central column of the valve body. Bromley Plumbers have expert knowledge on this subject. Both are very quiet when they operate however the float cup will be slow to fill the cistern if it is fed from a storage tank rather than mains supply. In these slimmer more modern systems the old syphon flushing method is replaced by a plastic valve operated flush mechanism that is operated by button fitted in the cistern lid. This also incorporates an over flow. The button is in two parts, depressing one part for a short low volume flush and both together for a full volume flush. The button is linked to the plunger rather than the older style wire link float arm system. Installing.The valve design is very ingenious but can be very tricky to make adjustment for a correct fit so when installing the valve must be adjusted so that the critical level on the body of the valve is at least 25mm above the top of the overflow pipe. There is a threaded shank at the base of the valve assembly which gives the relevant adjustment so that correct positioning can be achieved. Guaranteed installation work for this equipment can be carried out by a Bromley Plumber.The float cup inlet valve consists of a rubber ring seal at the base of the cistern which will probably need to be replaced in time but with spares available should not cause too much trouble. It is a good idea to keep any instuctions and drawings regarding the unit should you need to replace a defective seal at some point.
