Ideal Standard Close Coupling Ring Washer Doughnut Toilet WC Cistern

Product Information

To stop water running out of the cistern through these holes the fitting kit is supplied with 2 conical rubber washers. The thinnest end plugs down into the hole and as the bolts are done up, a metal washer on top crushes the rubber into the hole creating a firm seal. 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 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. I have not yet mounted the cistern on the toilet, but I have the feeling that something is not right.

If however you find that you still have a leak then you will need to remove the cistern again and apply some Plumbers Mait all around the doughnut, top and bottom. Once reassembled this should now fully resolve any leaks.Using a spanner if there are nuts present or your fingers if there are wingnuts, unscrew each nut and then carefully lift the cistern free of the toilet pan. 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. Note: There are several different sizes of doughnut so make sure that you get the right one. Measure the diameter of the base of the flush valve in the cistern and then you will know what size doughnut you need to ensure it fits correctly. Finally have a good clean up around the under side of the toilet and floor, removing any water that could cause make you think there are leaks but there aren’t and then flush the toilet. If all is well after any inspection all should be clear and you should now be leak free.

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. In almost all cases there will be at least 1 screw holding the top of the cistern to the wall or surface behind. Along with the through bolts, these will hold the cistern firm and level. However this issue would not just become apparent after flushing the toilet, there would be a constant leak.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. The close coupled toilet is a fairly modern iteration and was meant as a replacement for the older and less efficient low level toilet. This is a problem in itself as the two types of toilet suite are very rarely interchangeable due to their size and layout. To see how to get over this problem go to our project on changing toilets I realise this is an old thread however my experience may be useful to others. I also had a siphon fault with toilet marked M360 from Ideal Standard made in late 1995. I believe the model name is Reflections or Meadow and it was designed as a 7 litre flush. Note: If there is no isolation valve installed then now is an ideal time to install one. See our project on how to fit an isolation valve for help on how to do so. 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.

If the actual 4 inch waste outlet for the toilet was leaking then this would also result in water pooling behind the toilet and in the area of the connection itself. We are currently using Royal Mail Parcelforce and DPD as our delivery providers, all small items will be delivered by Royal Mail, these can take up to three working days to reach you. If these rubber seals are not installed correctly and aren’t actually creating the required seal they’re supposed to, no matter how slight a gap there is, water can easily leak down through.

However as this water would be foul water e.g. water mixed with waste it wouldn’t be clean like fresh water and it would also stink! 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?? With the wall fixings removed the final job before removing the cistern is to loosen and remove the through bolts holding the cistern to the pan.
