what you need first is to check to see if your bowl is out of level then use a snake rotor to clean any mess in the bowl then flush this should solve your flushing problem

Depends how old your toilet is, it may be a calcium build up problem on your little inlet pipe inside your tank, but first check your water shut off valve on left side of your toilet near the wall....It may not be open all the way OR the valve has an issue...

Hey, One thing is that maybe there might be some loose plastic shavings in the fill line. From the Factory? or maybe was inside the water line going to the toilet when you connected the line to toilet. Shut off the water and get some towels and something to catch the water and disconnect it from the toilet and use bowl or what ever to catch the water and slowly turn it on and see if anything comes out. Maybe if it is in the line inside the toilet it might fall out by lightly tapping on the fill line inside the toilet to help it fall out. Just a thought when you said it "Sings" that sounds like trash inside the line going to the filler tube and bowl, hey try it who knows it might work. Okay

Hi,

First, carefully remove your tank lid, and place it where it won't break or fall. Look for a four-digit number located on the back of the tank, near the water level mark. This is your tank model number. If the number starts with a two, it is a one-piece toilet.
