A Great Day Starts With a Great Post.

Let me tell about myself before I start Writing this Post. My name is Matthew, and I’m a backup plumber. Today I decided to write a step by step guide on how to install a toilet while sitting in the office. Hope you enjoy reading it. I think this post going to change the way you think about plumbing, and hopefully, in the end, you realize that everyone can do it with just having the right materials/tools and little extra time 🙂

 

There are many reasons to install a new toilet.
Your toilet might be old and you need to replace it, or you might have flushed something which is blocking the toilet or maybe you are just looking for an upgrade.
We are going to teach you, step by step on how to install a new toilet.

Installing a Toilet can be a D.I.Y project if you are relatively handy.

However, you can get it done with the help of a plumber, and use this guide for your knowledge.

Tips:

Installing a new toilet can be quite easy, a Plumber can install it within a few minutes.
However, a licensed plumber has installed many of them in the past. Therefore, he has the experience to install it quick, safe and without any leaks.
You need to remember that the speed doesn’t matter here and the goal is to get the job done correct and safe, without the need of redoing the whole task.

Materials:

Below are a list of materials you need before starting the job.

1) toilet-

Depends on the Brand most toilets are available to purchase in one package ( bowl, tank, and seat) and the pack might include gasket and bolts as well, while some are sold separately.

Any plumber recommends a toilet with 1.5 gallons per flush

2) Toilet anchor bolts or closet bolts-

No-cut or self-adjustable toilet bolts are pretty easy to install, and there is no need to snap or cut the excess length after mounting the bowl.

Tip:

Make sure that the flange is not broken, If you are replacing a toilet which is loose

You can use a repair flange if you find out that the flange is broken, you need to screw the repair flange on top of the existing flange before installing the toilet bolts.

3) Wax gasket(Wax ring)-

Plumbers use two wax-gaskets (one with the bell and one without) if the flange is sitting lower than the floor.

4) Flexible or braided hose for the water supply

A braided stainless steel hose for the toilet comes in a variety of lengths, and the most typical size of the end connecting to the toilet is 7/8″, and the other end of the shut-off valve is 3/8″.

5) Shims-

Sometimes you need to shim the toilet if the floor is not level or the toilet is not sitting flat on the floor.

Assembling the Toilet

In most cases, manufacturers include the necessary parts for attaching the tank to the bowl and the fill kit inside the tank is most likely installed.
You need to make sure that the installed parts are tightened enough (do not over-tight the nuts)

You can install the toilet bowl before attaching the tank if you feel that the tank adds weight to it and makes the installation difficult.
However, you can assemble and attach the tank if you are working in a tight space to make the job easier for yourself.

1) Make the flange ready for the installation-

Check the flange and repair it with the repair kit mentioned above if it is broken.
Center of the flange from the side walls should be at least 15″.

2) placing the bolts-

Slide the closet bolts into the place and lock the washers, make sure they are centered, the distance between the bolts and the back-wall should be at least 11.25″.

3) Putting the wax gasket-

Position the wax ring on the flange ( you can place it on the underside of the toilet as well ).
As I previously mentioned you could use two wax-gaskets one with the ring and one without if the flange is lower than the floor.

4) Setting the toilet-

Lift the toilet and move it over the floor flange, make sure that the holes are aligned with the bolts, set the toilet when it is in position and press it against the floor.

5) leveling-

Use the torpedo level and make sure that the toilet is leveled, use your tape measure if there is a gap between the tank and the back wall, measure the sides of the tank from the back-wall and make sure that the toilet is straight.

6) Shim the toilet and tight the toilet bolts-

Now that the toilet is leveled and everything looks good, you need to tighten the nuts and install the bolt caps.
Remember to snap the excess length of toilet bolts before installing the caps if you are not using the self-adjustable bolts.

7) attaching the supply line-

As I mentioned previously, you need to purchase the right length of supply hose to avoid extending it.
Connect the smaller side of the hose which is 3/8″ to the shut-off valve, and the flex hose should have a rubber gasket, and you do not need to use Teflon tape on the threads.

8)Fill the tank and adjust the filler valve-

Adjust the filler valve and fill the tank, make sure that the flapper is working properly and water stops when the tank is filled.

9) Test the toilet for the leaks-

Flush the toilet at least five times, check for any leaks and drips.

Caulking the base is not necessary and is optional, but if you decide to use silicon around the base then leave a gap to notice the possible leak in the future.

You should be able to find all the mentioned parts and tools from the closest home hardware store, but in case if the home hardware is not carrying some of the parts then you can visit a plumbing supplier.
