Shortly before xmas Ocean Wolf decided to throw its crew a little challenge. The toilet vacuum pumps demanded emergency maintenance. 
The Dometic Sealand pump for the port cabin failed to keep vacuum. Given its location behind the pump for the port cabin we decided to give them both a clean and replace the duckbill valves and the ‘plungers’. It was a shitty job but turned out well.
It also inspired the creation of a detailed spares inventory such that it’ll be easier to find the required spares next time around.
