Flushing with fresh water

[NormanS]

We'll have to disagree on this one. I'll stick with practical experience over many years and with toilets that are impossible to cross contaminate.

One wonders why, when you are so confident, you asked the question in the first place?

I have found that the way to avoid eggy pongs in my toilet is to give it a long and vigorous pumping before leaving the boat and long after the toilet has last been used for sh*t. I believe that even when the incoming water looks clean, enough microorganisms diffuse from outlet to inlet to breed and produce the smell.

It is surely significant that a properly installed Lavac with inlet and outlet on opposite sides of the boat never smells. The same is true of my Jabsco LITE. In both cases seawater supplied to the bowl by a pump upstream of the toilet is totally separate from the downstream pump that removes the bowl contents. Except for the case in which discharged water is resupplied to the toilet.

That's easy Norman, I wanted to know about the technical side of the installation, not the whys and wherefores of the smell. It is only thread drift that taken us down the excrement road!

I never had smell problems with my SL-400, which had intake and outlet on different sides and which pumps flush and waste water with opposite sides of a diaphragm, eliminating blowpast possibilities.

If it's a diaphragm and there's no problems with smell then it rather helps to prove Vic's point. The smells are nothing to do with sea water per se; it's all to do with effluent leaking past the piston and getting into the flush side.

There's NO WAY on earth I would want the flush side of our Jabsco heads connected to our fresh water!

Vic? I was trying to agree with Vyv!
