A tale of two toilets...

both toilets have SeaEra conversion kits installed. The aft toilet has a proper water level in the bowl, while the forward (newly installed) does not. Both toilets flush with the same amount of water but the forward toilet water level is too low.Should put a vertical loop in the discharge line to keep water in the bowl?

Not sure I understand... but I can tell you our single toilet ejects through a joker valve into an overhand loop before wandering downward, over, and then back up to our holding tank.

Anything that makes it over the loop... stays in that hose... and the joker valve keeps any "leftover" liquid -- that didn't make it over the loop -- from traveling back into the bowl. (When the joker valve is still working as expected.)

Adding a slight bit of water to the bowl afterwards without actually pushing the flush bottom lets us leave a little water in the bowl when we choose to. (Actually, our primary flush button usually adds a little anyway.)

Iow, you want your toilets to hold water in the bowl "like the one at home?"

Marine toilets aren't designed to that because heavy seas or even wake that toss a boat around can send that much water all over the head. Some electric toilets can be ordered with an optional flush "button" that provides a choice of bringing water into the bowl and holding it (recommended ahead of solids...use a cup to add water from the sink if you don't have that flush option), "dry" flush and simultaneously bringing water in and flushing it out at the same time.

Some boat owners, primarily those who own houseboats on protected inland waters, plumb their toilets to hold water anyway...by running the discharge line straight up about 3' and removing the joker valve. Water--or waste if the toilet isn't flushed long enough to clear the top of the loop and followed by enough water to rinse behind the flush--runs back into the bowl. A long discharge line that runs even a few degrees uphill can also allow water to run back to the toilet...a worn out joke valve will allow it to rise in the bowl. I suspect that's what's allowing one toilet to hold water, while the discharge line from the other one isn't plumbed to allow it.
