Leaking toilet - water inlet

Anonymous user 28/02/2024 - 3.24 PM

My toilet is leaking from the bottom at the point that the water supply joins the water inlet of the fill valve at the underside of the cistern. I've shut off the water and detached the flexible hose to find that it doesn't join directly onto the threaded screw, but the lock nut is also an adapter from what looks like 3/8" to 1/2". It was this lock nut/adapter that was cracked and causing the leak but I can't find a replacement for this anywhere. Is this something that I can replace or do I need to replace the whole mechanism? And if the screw thread coming out the toilet is too small for my flexible hose fitting do I need to replace the entire toilet? It seems to be a very strangely fitted toilet to me. Thanks in advance for any advice! Edit: Thanks for the feedback. I've just removed the water inlet valve and the hole in the bottom of the cistern isn't big enough for a 1/2" screw thread to fit through. Do I have to replace the entire cistern?

Best to replace the inlet valve. They now all come with 1/2" thread. Try to get one with a brass thread rather than plastic. You can buy them for about £8.00-12.00.

If its leaking from the hose going into the toilet you may just need to change to fiber washer which are pence to swap. If you can't fit a 1/2'' valve through the hole you may be better fitting a new cistern or totally new toilet as you can buy a whole new close coupled toilet for £40. The size of a normal I let hose for the toilet should be 1/2'' anyway with a 15mm to 1/2'' flexible hose going from copper pipe to cistern

Get a flo-master from screwfix. £6.99... they come with a brass shank. I carry 5-7 as stock all the time. Great value for money
