Ideal Standard Close Coupling Ring Washer Doughnut Toilet WC Cistern

Product Information

Before doing anything, the first task is to turn off the water supply to the cistern so that you can safely disconnect the flexi hose or other means of connection. Jeez!! Is it just me or did your eyes glaze over after the first few words of this lot?? You would think anyone that can write like that could afford to get a real Plumber to fix it!! Oh well, as I aways say, the educated poor eh!! Then the real trouble began. Given its condition, it came as little surprise when I couldn't get the original close coupling washer to seal properly. I was pleasantly surprised that Screwfix's sister company B&Q sold the washers separately without having to buy the metal part as well so I bought one.

To allow water in to fill the cistern, normally a flexi hose connector is attached to a water supply pipe and then screwed on to the base of the fill valve. In some instances a flexi hose isn’t used and copper pipe runs straight to the valve.This is especially important if the leak is with a newly installed close coupled toilet! The through bolts, as stated above, secure the cistern to the toilet by running down through holes in the base of the cistern and top of the toilet. As we have discussed, the most common cause of close coupled cistern leaks is that cistern isn’t sitting at 90° on top of the toilet pan. If the cistern is leaning over, even a little, one side of the doughnut lifts and, with a lot of water pressure, the leak is exposed. If Plumbers Mait or a similar sealant isn’t used or the screw cap on the hose isn’t done up tight enough onto the fill valve then water can easily leak up through the threads. With everything cleaned and ready refit, pop the brand new doughnut down on top of the toilet cistern in it’s recess making sure that it is sitting correctly and flat on the toilet pan. When screwing up these bolts once they are inserted down through the toilet pan, if you don’t tighten them evenly and together so that the cistern is pulled down straight and level then this can also be a cause of leaks as the cistern will sit at an angle and not seal the doughnut correctly. Other Causes of Leaks From Close Coupled Toilets

I have not yet mounted the cistern on the toilet, but I have the feeling that something is not right.

This is the most likely root of the cause, however there can be others so read on to learn about how to resolve leaks with close coupled toilets. Why is my Close Coupled Toilet Leaking When I Flush?? Refit the 1 or 2 screws that secure the cistern to the surface behind but don’t tighten them too much, leave a little wiggle room. This is just to help hold everything in place and ensure nothing moves out of place. With the water turned off you can now safely disconnect the supply pipe. Before you do so though, place some old towels under the area surrounding the pipe and an old tray of some type. There will spillage so you will need to catch it all.
