What causes a toilet to lose some of it's water in the bowl? After flushing
it, it fills up just fine. When it stops filling, within 30 seconds the
water level in the bowl drops a bit (maybe 3/4") and stays there forever.
No leaks, two-piece toilet.
"7. Toilet Bowl Water Level Drops
After you walk away from the toilet and the tank has filled, does the
water level mysteriously drop? If so, two things can be wrong. The
toilet may be partially clogged. The clog can actually cause a siphon
and pull water from the bowl. The other possibility is more severe.
There can actually be a crack or small defect in the colon of the
toilet. This is the channel that water passes through to get to the
drain pipe. A colon crack or defect means it is time for a new toilet."
you may be overfilling the bowl. professor flush at fluidmaster is
"Toilet bowls in general A note on bowls in general: Each toilet
bowl is made so it can hold a predetermined amount of water. If you
purposely overfilled the bowl you would see in the minute following

more from buffalo ny: fluidmaster sells a fill valve with an
adjustable clamp that squeezes the small rubber hose that runs water

from the street here i don't always need it but you may, depending on
water pressure and tank size and bowl capacity. my goal here is to get
the refills after a flush to complete in 90 seconds or less. if you
have higher water pressure and flow by your toilet, optimize the flush
for full flush with a flusher fixer, and replace the fill valve too.
