From personal experience, I can tell you that repairing a marine head starts long before you leave the dock. Sure, you can access YouTube videos online if WiFi is available, you can find a schematic online if you have the model number and there are many marinas you can fly parts to or couriers that will deliver to remote locations. However, losing a marine head while on vacation changes everything. I have learned to do the legwork ahead of time and have spare parts on board.
Key things to have:
If you have the original owner’s manual – fantastic. If not, contact the manufacturer and download a copy. You won’t always have access to the internet so a printed copy onboard is a great idea.
- Make sure the model number matches the Owner’s Manual and download a schematic.
- A common fail, is a simple o-ring. The system loses pressure and the pump runs every 30 seconds or so. Always have spares, this is the kit that I have onboard, https://amzn.to/43FrLT9
- Another common fail is a duck bills so have extras.
- I have a repair kit and a complete replacement kit onboard. It only has to happen once in a remote location and you will easily justify the cost! I recommend Environmental Marine in Florida https://www.environmentalmarine.com/ or Marine Sanitation & Supply in Seattle https://marinesan.com/vacuflush/vacuflush-maintenance-kits/ They both ship to Canada and they are both a wealth of information.
