First, low water in the toilet BOWL case. If the water in the toilet BOWL is low after flushing, I see four likely causes, in order of most likelihood -. 1) the fill valve is not putting enough water into the toilet bowl.
After flushing, the water level in the bowl drops a bit. It takes about 30 seconds and loses between one and two inches. It starts dropping fairly fast, then slows, then stops, and then the level holds steady until next flush.Bowl still has a nice, respectable amount of water.f the water level doesn't drop so low that air is sucked through the bowl, causing a 'glurk-glurk-glurk' sound it's likely fine. (That sound is usually indicative that there's a partial clog preventing the vent from equalizing the pressure as the bowl drains.). share | improve this answer.
