Close Coupled WCs and Pushbutton Cisterns

This modern style WC does away with the pipe that connects the cistern to the pan. Water flows from the cistern through a ‘moulded-in’ channel in the pan to the rim. The cistern is bolted directly to the pan and a rubber seal prevents leaks at the joint. This style often features compact cisterns with push button action and lower water usage. South West London Plumbers can fit this system.


The cistern may incorporate a diaphragm valve, but is becoming more common to find close-coupled WCs with pushbutton continental style cisterns. Here, the traditional handle is replaced by a button on the top of the cistern. Usually the button is split, to give a dual flush facility of 4-6litres or (7 or 10 1/2 pints), helping to save water.
Push-button cisterns use a different type of valve, which is activated by a cable release. A small float controls the level of the water in the cistern. The valve usually incorporates an overflow, which allows water to flow into the toilet bowl, rather than outside through an overflow pipe, if there is a problems in the cistern. A South West London Plumber is experienced with this type of WC.


The mechanism fitted inside the cistern is completely constructed from plastic, so it will not rust with time or exposure to water. As a result, there is less to go wrong, but if any problems occur, spare parts may become annoyingly harder to identify as there are quite a few different types on the market. These cisterns produce a faster flush, which doesn’t give the same cleansing action as a slower, siphon-operated flush. However, they are quiet in operation, fill quickly and allow for a very slim-line cistern to be fitted, helping to reduce the footprint of the WC
