I noticed the seacock for my head macerator is frozen open ( In don't know when it was operated last as I bought the boat in December). I don't discharge in my area but obviously if boarded by the coast guard I'd rather have it closed. It's hard to get at in my boat. Is there some kind of a grease fitting (zirk) for that or do I just use penetrating oil?
