Re: Seacock fall apart in my hands while removing....
It looked like the thru hull walls was just weaken over time, as this is where the seacock immediately separated (metal twisted off) from the seacock. I disagree with everyone that I have a extensive problem with electrolysis as I replaced majority of the seacocks on the sailboat and this one, although it looked like it could have lasted another 5 to 10 years, twisted off at the thru-hull threads while the others, looked like worse but was quite solid once I finally was able to remove them.
I really did not mean to have this thread jump into other topics like maintenance, everyone's thoughts on how long or short a seacock should last, electrolysis, causes, etc... It was just to say that sometimes a part on your sailboat or anything else, looks solid and well maintain but the assembly was the weakest one out of the entire seacock replacements, including two that were marine plastic seacocks. Perhaps I did not word my original thread properly.
