Every year, before she goes back in the water, the seacocks are inspected and serviced - usually just by re-greasing the cones and tightening to suit. The last day or so before re-launching are alway a bit frenetic, so to re-assure myself that the jobs has been done - and that all the valves are back together and closed (as they should be when not in use and on the water) I take photos of each one.

| Some our sea-cocks |
Metal seacocks can suffer from dezincification, when the zine in brass is lost to electrolytic action in the same way as a sacrifical anode, which makes material brittle. Its good practice to check every year for the distinctive pink colour which indicates this process and replace if it is eveident.
