A vented loop is needed in the intake on any
toilet that's installed below the waterline. It needs to be at least 6-8" above waterline AT ANY ANGLE OF HEEL, NOT just when the
boat is rest...which on most sailboats puts it 2-3' above the bowl. It should NOT be installed in the intake line between the thru-hull and
pump...it'll interfere with the toilet's ability to prime if you put it there. It needs to be installed between the
pump and the bowl, which requires replacing the short piece of hose the
toilet mfr used to connect 'em. You'll see illustrations in the on page 3 of the owners manual for the
Jabsco manual toilet
Jabsco 29090 Manual Twist & Lock owners manual and on page 5 of the owners manual for the
Raritan PHII manual toilet
PH II Owner’s Manual
If you'll only be
flushing into a tank, no discharge vented loop is needed, but one is needed if you also flush directly
overboard.
That covers the basics...I'll be glad to answer any questions if you need help with the details.
