Cistern Problems

For Cistern Problems, Call First Call Plumbers, Edinburgh 0131-669-1007There can be quite a few problems that can occur with the Cistern. It does not flush when handle/chain is operated, it fills very slowly, water comes out of the cistern overflow outlet, the flush does not clean the pan or even that there is condensation on the outside of the cistern.

If a syphon type of cistern has never flushed properly, the likelihood is that the water level is too low – it should be about 12mm (half inch) below the overflow outlet.  To correct this, raise the height of the float, the method depends upon the type of valve/ball fitted.

If a linkage has become detached within the cistern, this should be fairly obvious as the handle/chain will loose its normal ‘feel’ – i.e. the handle or chain won’t return to its normal position. Most linkages which have come loose can just be refitted and tightened after removing the top of the cistern.

If the cistern is a direct action type syphon type, the flexible diaphragm on top of the perforated disc may have become torn.

If a cistern fills very slowly, more than 2 minutes, this problem would normally be associated with the ball valve which fills the cistern with water, possible causes include:

  • The wrong type of valve nozzle is fitted, a mains valve nozzle fitted where the valve is fed from a water tank – most valves are supplied with both nozzles, the appropriate one needs fitting at the time of installation.
  • Low water pressure in the feed pipe – either a valve has not been turned fully on or there is an obstruction in the pipe.
  • The valve itself may have become clogged by scale or muck in the water supply.

If a cistern does not flush when handle/chain is operated and if a syphon type of cistern has never flushed properly, the likelihood is that the water level is too low – it should be about 12mm (half inch) below the overflow outlet.  To correct this, raise the height of the float, the method depends upon the type of valve/ball fitted.  On some set-ups there is a hinge in the arm between the valve and the ball with a lock nut/screw – loosen off the nut/screw and adjust the hinge.  The final arrangement is where there is a solid brass rod between the valve and ball without any adjustment; in this case, the rod needs to be physically bent.
