There's a lot of variety in the works in the toilet tank. Assuming this is not a pressure-assisted toilet-----First understand the three valves are:
1. The shutoff valve - on the supply line coming into the toilet tank.
2. The fill valve - inside the tank, opens with the float descends, closes when the tank fills up.
3. The flush valve - inside the tank on the bottom. Common old style is a flapper on a pivot. Yours may operate straight up and down rather than on a pivot.
Three very common problems are----
1. The chain that connects the handle to lift the flush valve is getting caught, not allowing the flush valve to close.
2. There is problem with the flush valve being able to get a good seal when it closes - could be debris or misalignment.
3. The fill valve is not closing when the tank is full, could need adjustment or there is debris preventing the valve to seat.
.
Here's are some steps to diagnose---- close the shutoff valve. Wait a few minutes as you watch the level in the tank. If the water level decreases, you have problem with the flush valve.
To confirm the fill valve as the problem, turn the shutoff valve back on. Lift up on the float that is supposed to turn off the fill valve. If it shuts off, you should be able to adjust it - most have a +/- plastic adjustment screw. But if raising the float by hand only slows it down, you have problem with the seating of the fill valve - which can sometimes be cleaned, but more often would need to be replaced.
I hope this is helpful. Thanks for using FixYa.
