How do I remove a waste basket (long thread) from a porcelain basin unit? I have removed the U bend and undone the large nut on the waste, however I cannot remove the waste because the thread is totally filled up with sealant which is working perfectly to stop any possible leak! The downside of this is the fact that I cannot budge it! Any ideas appreciated please.
Welcome to the Bunnings Workshop community. Thank you for joining us and sharing your query about how to remove your basin waste.
I suspect that the basin waste has been hand-sealed with silicone. I suggest using Selleys 375g Silicone Remover. Once applied to the sealed area you will need to wait for it to soften the hardened silicone. When the seal is workable, you can slowly chip off the silicone with a flat head screwdriver, taking great care not to damage your porcelain basin in the process.
Please let us know if need more assistance.
I am not so sure that it is a silicone sealant that has been used, it almost looks like putty, and is quite hard, certainly harder than silicone. The reviews for the Selleys 375g Silicone Remover are not at all encouraging either, I sort of feel that is not going to work. There is very little room to get any sort of tool in between the thread and the porcelain hole in the sink. Further thoughts please.
As you have a lack of space Would a hacksaw blade work to sand /chip it away. You can get one handed handles, Or possible get a belt sander belt turn it inside out and use it to "hand sand" it. If you dont need to keep the original, you could just cut it off flush against bottom of nut or if you have a renovator tool cut across the nut and prise it off this would mean replacing the nut only.
It's great that you've received some excellent advice from @JDE. If removing the waste has become truly difficult, I suggest using an Ozito PXC 18V Multi-Function Tool. Using the steel cutting blade should cut down whatever is holding the waste in place. You may have to cut it in two different spots to completely remove it. Just a friendly reminder to please take care and not damage the basin in the process.
