Crawling under the head
sink and twisting, I found the seacock connected to the macerator. It has a lot of green corrosion
on it, which appears to originate from the connection to the hose from the macerator. (first picture below)
I've cleaned up seacocks before, but this one has a couple of issues.
First, it is below the waterline so I have to proceed carefully.
Second there are 1/4" plugs on each side. These plugs have corroded to to the point that they crumbled on the attempt to unscrew, leaving a pink residue in the sockets. I think the PO accidentally used brass plugs, of which there are many on the boating
store racks, instead of bronze (which I had to special order). Using brass plugs in a bronze seacock is consistent, I believe, with this result.
Question I have is how to clean out these sockets? I've gotten as much as I can by scraping one of them. but there is still too much residue in the socket to even partially screw in the new plug
. (This is compicated by where this seacock is, being hard to reach the top & bottom sides, and that I only have a side view of it with my eyeballs. I use my digital camera
to get a real look at it.)
I will probably arrange a day haulout next week. But what approach to take then?
Is it possible the seacock has been damaged beyond what cleaning
out the socket would fix?
Here's the seacock:
