Boat Building can be soooo Glamourous!
Certification in VacuFlush Marine Sanitation Devices (aka toilets and poo tanks) This last week I got some training on installation and maintenance of VacuFlush Systems. Put on by Marine Sanitation of Seattle. Anyone whoever has owned a boat with a head knows these things are often smelly and a pita to maintain. Inland and coastal overboard discharge regulations require holding tanks for the poo. So, head systems have become complicated. Nevermind they are often manual and require some knowledge by the user on how to properly operate. VacuFlush systems put a new twist on head systems. They have been around for years and are often found in motorhomes and travel trailers. The idea is that it relies on a vacuum, instead of water, to flush the bowl. A pump keeps the system behind the bowl in a vacuum, then, when flushed, uses the vacuum to evacuate the bowl into the holding tank (quite quickly actually). In fact it uses a little fresh water, but overall consumes %60 less water than regular head systems. And, since it is fresh water, it is less smelly (often it is the seawater that is the cause for head smell). And, now that I am in the know, they are easy to service and repair. One nice thing about these systems is that they have created "all-in-one" systems that have the holding tank, vacuum pumps, overboard and deck discharge fittings. Designed to fit some of the more common spaces. We will probably use two of these all-in-one units for the Westsail as they are compact and easy to install.
