The first pump died after 15 seasons. It sounded like a jack-hammer but was a reliable crew member on our boat, sort of like Relic on The Beachcombers. Part of my bedtime ritual was turning the breaker off so as not to be awoken but sporadic bursts of pump.
This pump was made in the USA in 1999 and judging by the date, I’d say it was the original freshwater pump. It started weeping at the end of last (2014) season and I ignored it. At the end of this season, shortly after finishing out trip to the 1000 Islands, it quit (almost exactly like the fridge did last year). Upon inspection the inner sealed-bearing failed and flooded the electric motor. Rust-brown water trickled out of the motor case, it was done.
The toilet to holding tank hoses on Tortuga, I assume, are original and the source of our stinking shame. We developed a big odour problem by the end of season and eradicaton of odour was a priority job for 2014 launch. I picked up a new Jabsco pump unit on sale at the end of last season as the entire unit was cheaper then a gasket rebuild kit and I could see that the flimsy plastic pump was distorting, so I wasn’t convinced freshgaskets would stop the spurts of water when pumping. Although not a source of odor, water spraying out of your toilet isn’t exactly the experience I’m after.
I contemplated using PVC tubing instead of replacement hose as it is much cheaper and will never smell, but the complete lack of access to the hose run made me I realized that while I might (no, it’s impossible) get a pipe in, there would be no way to secure the pipe from banging around. Securing PVC in marine installations is key as flexing and movement will lead to cracked joints and leaks. Hose it is. Trident, the industry standard is guaranteed for 10 years, in fresh water I should be able to get 15-20 years – who knows if I’ll have the boat then?! I’ve gleaned what I can from forums and Peggy Hall and bought some holding tank treatment (Happy Campers) to keep the vent air fresh. Final task is to back flush the vent to ensue proper airflow to the tank.
