Dear Jean
Thanks very much for the prompt reply. Regarding your first point, yest my plan was to Tee into the fresh water before it gets to the pump that pressurizes the fresh water system. So it would seem to me this would not put pressure on the toilet system, it should be the same as the salt water input from the sea chest. You also have a good point about toilet water backing into the fresh water tank. If I installed a check valve (a valve that only lets water flow in one direction) at the Tee, many feet away from the toilets, wouldn't this take care of the toilet water backing into the fresh water tank ?
Thanks again

Fresh water to toilet bowl

If you want to do that you should remember that on a live ship the fresh
water system is constantly pressurised and therefore fresh water will be
continuously seeping into your toilet bowl and draining your fresh water
tank. To avoid that you need a solenoid valve switched on by the red toilet
flush button to open the fresh water line when you do flush and keep it
closed otherwise. Also you should be careful about the possibility of your
toilet bowl water backing into your fresh water tank with all attendant
problems.....

To avoid such problems you would have to run a fresh water pipe direct from
the tank to the toilet flush sea water hull intake (before the flush sea
water pump) and Tee it there. This involves more pipe runs in awkward places
but would be the safest way of doing it, both avoiding the constant pressure
problem and the potential water flow back from the bowl.

I had discussed this issue with Amel for my boat when ordering her but they
did not want to do it then. They'll come to it some day.

Good luck,
