The first thing you’ll need to do when your toilet seal is broken is, switch off the water supply. Usually, there’s a valve to control the water supply right under the tank.
Although, you can also do it by cutting off supply from the main source.
After that, use the flush to get rid of the water in the tank. Lastly, you can use a shop vacuum or a sponge to drain the water in the bowl.
Step 2: Detach the Tank Hose
Now that you’ve stopped the water supply, it’s time to detach the hose. This hose is used for connecting the bowl to the tank.
There might be some water in the hose, so it’s a good idea to put a bucket under it.
As most people don’t need to repair their toilet that often, the bolts might look old and rusty. In such cases, applying some penetrating oil will work.
Now, wait for 2-3 minutes and try loosening the bolts.
Step 3: Remove the Bolts
You’ll need some space to work, also the toilet might be too heavy for carrying. For this, you need to remove the bolts attaching the tank and the bowl. By removing those, you’ll be able to move those separately.
However, make sure to put 4 blocks in a corner of the room. You should place the blocks before starting out. You see, these blocks will keep the toilet drain undamaged.
A piece of quick advice, try placing the blocks at a little angle. By doing this, you’ll prevent the toilet from falling over.
Step 4: Take Out the Toilet Bowl
First, put down the toilet seat. Now, pick up the bowl, keeping it parallel to your floor. Also, make sure that the existing toilet doesn’t come out of its place.
Now, put down the toilet on the blocks that you’ve previously placed.
Step 5: Pull Out the Wax Ring
Before starting, put on some disposable gloves. Also, keep the room well-ventilated as this kind of project can get messy.
First, using a putty knife, remove the ring. Then, use a clean cloth dipped with mineral spirits to clean out the anchor flange and the drain.
Now, remove the old mounting bolts and inspect to see if there are any damages. Keep the drain blocked with a large towel or rag to prevent things from falling into it.
Moreover, it’ll also keep out any kind of bad smell from spreading around the house.
Step 6: Replace the Wax Seal

Now, put your disposable gloves on and add the new wax seal to the toilet outlet pipe. Although, be gentle about placing the wax seal as pushing it too hard can put it out of shape.
Step 7: Connect the Toilet
Now, pick up the toilet that you’ve removed and put it in its rightful place. Although, remember to put the toilet in the exact previous position as you’ll need to reconnect the mounting bolts.
Lastly, move it gently until it has a tight seal with the seal under it.
Step 8: Tighten the Bolts and Nuts
After the toilet is perfectly in its place, it’s time to tighten the nuts and bolts. First, attach the washers and nuts on them, and tighten them.
However, never over tighten any nuts or bolts as too much pressure can break these things.
