No Flush




The toilet is one of those things that you think will last forever, and that is sometimes the case, however you can bet that the one time you want it to flush it won’t, no matter how many times you try. Try giving the cistern and flush handle a good thorough visual inspection just to check if there is anything that is obviously wrong. Shoreditch Plumbers can inspect plumbing and also diagnose and repair problems. If there is nothing that stands out, then it will more than likely be down to a component failure of something a little more closer to the water outlet. The most likely failure is something called a diaphragm washer that sits under the siphon arrangement.


Check and Replace:

Firstly isolate the water supply to the cistern and empty it of all the water by flushing. Wipe out any remaining water. It might pay to take photos as you continue the task. Lift the siphon from the body of the cistern (if you have any doubts, definately take a photo of this part as you dismantle). Unhook the linkage to the lever arm, if the arm of the float operated valve gets in the way, you may need to remove this also. With the siphon removed you will now be able to see beneath its base and see where the perished diaphragm washer sits. A Shoreditch Plumber can take on any plumbing task.


Remove the hook from the shaft that pulls the diaphragm, it should allow the diaphragm housing to drop from the base of the siphon. Fit the new washer and fit the parts back in reverse order (check any photos you took). Restore the water supply and check for any leaks. All of the jointing washers need to be in a sound working condition, if they are not, put some PTFE tape around the joining parts (not on the threads).
