i fitted one sea toilet with a very short inlet pipe just above the floor of the bowl. pumped virtually dry, never smelled.

So how does the outlet smell get back into the boat when you are pumping out then? /forums/images/graemlins/confused.gif

The Headmistress certainly.
It is organisms which develop in the inlet pipe. There are more complicated ways to cure in by T'ing a hose into the inlet from the basin waste with a T-switch. This enables you to run a basin full of fresh water into the inlet pipe before you leave it{snip}

Agree with that, and can testify to the success of tee-ing the heads inlet into the sink drain. About a tenner's worth of bronze fittings off ebay, and it's a proper job.
In normal use, the heads draws seawater in through the sink outlet skin fitting, just as it would it's own fitting (which becomes redundant). Before leaving the boat, close the sink outlet seacock, run a few pints of fresh water into the sink, and pump the loo until it draws the fresh water through, and the inlet runs dry.
Result: COMPLETELY pong free loo. Not previously achieved by tipping anything down the pan (incl. fresh water). As long as you can get a plain tee fitting in below the water-line, you don't need any additional valves, etc.

An aspect which has not been mentioned is that in many pumped sea toilets a humble O-ring on the pump piston is all that seperates the foul outgoing water from the fresh incoming water. water.
Once things get a bit worn , you can get leakage past the O-ring and the inlet water gets contaminated.
You can eventually clear this with additional pumping but its not always obvious.
Basically it is poor design. O-rings were never intended for this type of application and a pair of back to back lip seals would have been the correct engineering solution OR the LAVAC principle.
