How to Fix a Toilet Seat that Keeps Falling Off

The sturdiest component of your home plumbing system is the toilet. However, I would guess that there has never been a home that has not had problems.

Problems such as a runny toilet, a clogged toilet, and a leaky tank are some of the most common you can have with your toilet.

Another common problem is a toilet seat that keeps falling. This can be a real nuisance but fixing this problem is not a difficult task.

 Luckily, most of the plumbing problems you can fix yourself pretty easily, instead of calling a plumber and making him your new best friend. If you have had or will have this issue here are suggestions as to how you can fix a toilet seat that keeps falling. 

How Do you Fix a Toilet Seat that Keeps Falling off?

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.

If your level shows that your toilet is slanting either to the front or back, you will need to buy toilet wedges. They are easy to install and are inexpensive to purchase.

These wedges look like tiny door stops. They are placed by sliding them under the base of your toilet to make it level depending on which side is slanting. Since your toilet seat does not sit upright, you will need to place these wedges at the front of the base of the toilet.

Ensure that the wax ring isn’t too cold otherwise it’ll be too hard for the toilet bowl to seat properly and this could result in the same problem you’re trying to fix. if the bowl isn’t level and not aligned with the wall, you can add shims.

Then fit the rubber gasket onto the flush valve opening on the bottom. Positioning the tank over the bowl, tighten the nuts and washers onto the mounting bolts as well as the hold-down bolts at the base with an adjustable wrench.

During the entire process you should constantly use a level to ensure that the toilet bowl is still level throughout the process. Using a plumber putty(or silicone caulk), seal the base of the bowl after filling the decorative caps with the plumber’s putty and putting them over the head of the bolts, you should be nearly finished.

Finally cut the end out of your supply line stub and attach a shut-off valve. This valve will connect to the flexible tubing. Connect the tubing to the bottom of the tank where a supply stub out will be visible.
