I am replacing a bottom-entry inlet to a low-level toilet and no matter how carefully I tighten the external white-plastic nut I always get a leaky joint! The inlet came with a conical rubber washer to be placed inside the cistern (cone-side down), but I have my doubts as to how effective this is, as the hole at the bottom of the cistern doesn't seem to be exactly circular.
I have tried inserting another rubber washer between the cistern and nut (should it be plastic?), but this doesn't seem to make any difference.
Could I use a sealant between each part of the joint? If so, which one does not degrade when constantly underwater?
This should have been a simple DIY job (so my wife keeps telling me), but it's driving me nuts! Any help would be appreciated.
