Inlet pipe of water flush to the toilet is completely calcified!

Thanks for the two pictures.

Based on my approach:

- Grab a wet/dry vacuum and first vacuum the inside of the part – you obviously have a lot of junk inside, which can also prevent your drain stopper (that pipe that comes in from the top into the drain to stop the flow at the end of the rinse) from sealing the drain tightly. For you, a thin trickle must have been flowing for ages.

- then completely seal the lower outlet and fill up with descaler to the top edge of the pipe

- then repeatedly vacuum the descaler (or let it drain and reseal fresh) and refill – because with that amount of lime scale it will neutralize itself relatively quickly repeatedly.

I am personally quite cautious with the motor cable snake – after all, it’s just a plastic pipe...

It’s a lengthy process – but still better than breaking it open...

Thanks for the info

This morning the water was drained, the pipe was sealed and descaler was poured into the pipe and now we wait and see.
