About this deal

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 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. 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. 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.

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. 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. 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.

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.

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. If you have ever seen an old and aged piece of rubber then you will know that it looses it’s flexibility and essentially dries out and becomes brittle. At this point it will have lost it’s ability to form a decent seal and will then start to leak. Again if this is a newly installed toilet and you have just noticed a puddle of water on the floor then it may be coming from the incoming water supply and where it’s attached to the toilet fill valve or flush valve as it’s also known.

However this issue would not just become apparent after flushing the toilet, there would be a constant leak. 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. 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. 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 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.
