I think 90% of toilet problems on boats is from not flushing
through enough to get clean seawater all the way through the anti-siphon loop. That includes hose calcification problems.
I get an awful stink on board the first time I flush a toilet after the boat has not been used for a few weeks. From the microorganisms which died in the intake side of the system. Then I find that as long as you keep the toilet and heads compartment clean, and flush lots and lots of seawater through every time you use it, it smells absolutely fine.
When you leave the boat, close the intake seacock and flush out the toilet and discharge side with fresh water
. Then shut off the discharge seacock. That will help prevent calcified lines. But it won't stop the critters from dying in the intake side.
Another tip -- don't let men
stand up to pee in a seaway. The resulting mess is very unpleasant, and will contribute to bad smells if not cleaned up quickly.
Manual toilets, especially the Jabsco
ones with a straight rod an "t" handle for flushing
, are laborious enough to flush that hardly anyone flushes enough. I made a rough calculation that I needed to pump my previous Jabsco
manual toilet 24 times to get clean seawater past the antisiphon loop in my forward heads. Who pumps that much? Can sure make your arm hurt.
A big advantage of electric
toilets is that it makes it easy to flush enough water
through. The perfect electric
toilet (which doesn't exist, probably) would have a timer which would automatically put through the right amount of water.
