Use a Stanley knife blade to remove sealant, and go a buy a brass nut.  Toolstation 43258

i never use plastic nuts, I throw them in the bin.
I always have a min of 6 spare brass nuts in my van.

Reporting back to confirm no seepage since tightening nut with spanner almost 12 hours ago.

I'll acquire a Stanley knife blade and a brass back nut. Thanks for the product ID.

I don't know why you didn't tighten the plastic nut with a spanner as it was the very first thing you were advised when you first posted.

Well that will be a relief - you must have been good to burst!

Hi,

if it's fine, leave it as it is, but keep your eye on it.

You can get the extras in just in case.

Do you wish you had tried the 'tightening with a spanner' 6 days ago?

Barely made it.

I had already uninstalled the fill valve by the time I reported back. I done so with a view to applying sealant remover, which arrives in a few days.

Yes, definitely wish I tried tightening just a little more just a little earlier though the overall process has been highly educational.

Reporting back to confirm I removed the remaining sealant (entirely) and replaced the plastic back nut with a brass back nut.

The cistern inlet hole is successfully sealed and the toilet is operational.

Thanks everyone!
