1. Seat Placement Is Too Far Back In the Direction of the Tank

The most common reason for your toilet seat not staying up is the seat could have been placed too far back in the direction of the tank. When a new toilet is installed, the toilet seat angle is usually set beyond 90 degrees to the bowl.

The toilet seat after installation needs to be comfortably resting on the toilet tank. If this angle is less than 90 degrees for whatever reason, the toilet seat will keep falling.

If you find yourself in such a situation, here’s how to fix this problem. What you need: a screwdriver and pliers.

The seat is attached to two mounting bolts that are sometimes covered at its rear with the nuts on the underside. The nuts need to be loosened and removed, which depending on the age and condition of the toilet may or may not be a problem.

Be very careful when rotating hard to turn nuts with the pliers as you don’t want the pliers to slip and hit the toilet or something else. If you feel this might occur, protect areas close to the workspace.

Unscrew the seat, move it forward as far as you can away from the tank. Then screw it back. This should give the seat that extra length and angle to stay up.
