Seacocks

Just replaced the taps on the basin in the downstairs shower room with quarter turn ceramic jobbies. Struck me that the movement was not dissimilar to that of seacocks. Any reason why seacocks shouldn't use this material?

Just curious.

The ceramic discs can be scratched quite easily, which will lead to a slow leak. I've just had to replace my kitchen tap cartridge which was leaking ever since the burst mains last winter (burst pipe= debris in the water).
So I'd imagine that in a marine environment particulate damage would be the main problem.

I thought the whole point of ceramic was that it wouldn't scratch or degrade?

One of the taps in our kitchen leaks slightly . Ceramic disc type I assume.

Under normal circumstances they do last a long time but if they do get a bit of grit caught in the face and get scratched there is nothing you can do about it except change the ceramic valve*. At least with an ordinary tap you can just screw it down a bit harder!

* I guess, in theory, you might be able to use a piece of extremely fine wet & dry and regrind the scratched surfaces if you could hold them completely parallel. We have had one replacement in 13 years from 3 taps and the manufacturer replaced the valve free-of-charge.
