How to Install TOTO Toilet

The following information will help you install a Toto toilet easily.

Prepare the items you will need

Without the assistance of a plumber, you can install this toilet seat in only one hour or less with the correct equipment, supplies, and instructions, depending on your degree of expertise and the type of toilet. You won’t need to buy anything more besides the toilet seat to complete the project if your toilet maker has provided additional screws or other mounting hardware.

Shut off the main water valve and flush the toilet 

This will lessen installation-related leaks. Additionally, look under the toilet tank or under the sink for any other shut-off valves that may be located closer to the toilet. Make sure to shut off any valves, if there are any.

Measure floor drain pipe height

This is the connection point for your new toilet. You might wish to do this before choosing a specific model so that you can choose another one if it demands more or less height than what you have available.

Arrange tools and parts

Set up your equipment and the new toilet’s components on a flat, dry surface where you can work quietly for at least an hour. Verify that everything is in the package, including all required components and extras like wax rings, new seat rings, and other accessories. Label each piece with its matching number from the instruction sheet using masking tape (s).

Underneath the toilet seat, place anti-slip pads

Install the anti-slip pads underneath the toilet seat after setting the toilet seat in place. This site will contact the bolt-designated holes on the toilet bowl. The anti-slip pads prevent the toilet seat from rocking back and forth while fastening the bolts. The pads’ similar shapes allow them to fit perfectly in their allotted location. Verify that the tabs on the toilet seat’s two sides are open. The opening tabs make it easy to see where the anti-slip pads are located.

Toilet seat-bowl alignment

Line up the holes on the toilet seat with the holes in the toilet bowl before installing it. Be aware that the anti-slip pads attached to its bottom tend to move, and ensure they don’t stumble into the bathroom. Adjust the toilet seat after keeping it as level as possible when you put it on.

Bolts and nuts help to keep things in place

Make sure the anti-slip pads are positioned appropriately over the mounting holes one more time. After that, please take one of your bolts and insert it through a toilet seat hole. To keep the bolt in place, take one of your nuts and tighten it underneath the bowl where the bolt’s end lies. 

Repeat the process on the other side. Keep some wiggle room for any last-minute modifications by being careful not to tighten it. Expanding rubber bolts should be used instead of standard plastic ones in Toto toilets with blind holes rather than see-through ones. This guarantees that the toilet seat will be securely fastened.

Connect water sources with supply lines

Using a wrench, stabilize the connection between the tank and the water supply connector or the wall mount faucet adaptor, and turn it clockwise until the line is tight. Finally, test out your new toilet by spraying soapy water around all its connections with a flashlight and leaving the water running from both faucets for five minutes. If there are any such leaks, you can temporarily remedy them by re-tightening each leaking connection until the problem is resolved permanently.
