Many people choose to buy second-hand houses in order to save on renovation costs, but they often replace the old bed and toilet. So how can you measure the distance from the toilet flange without removing the old toilet? Let's take a look together.

How to Measure the Distance from the Toilet Flange Without Removing the Old Toilet:

You can measure from the drainage pipe as long as you are not on the top floor. Measure the vertical distance from the center of the downpipe of the unit above to the wall. This will give you the distance from the toilet flange. You can also measure the distance from the wall behind the toilet to the toilet outlet to determine the seat position. If there are screws, you can start measuring from the location of those screws.

Precautions for Replacing a Toilet:

1、Before replacing, check the level of the floor, the size of the toilet, and the sealing soft pad. It’s essential to inspect the drainage pipe beforehand for mud, paper, and other debris. If any is found, it must be cleaned out immediately. Additionally, if you discover that the floor is uneven during the replacement, you should level the floor first.

2、Also, check the fittings of the water tank for any leaks. If there are any issues, they should be addressed first to ensure proper usage afterwards.

3、It’s important to understand the methods for replacing a toilet so that you won’t need to hire a professional for installation. This can save some costs for your household. When replacing the toilet, choose one that has the same dimensions and specifications as the old one to avoid installation issues. Finally, when purchasing a toilet, be sure to choose a reputable brand and shop, as this ensures better quality and after-sales service.
