The above-mentioned guide will help in unclogging a clogged toilet. This can solve the overflow problem in your toilet if the cause of the problem is a blocked toilet.
But if the problem remains the same after applying the above-mentioned steps, might be the problem with the toilet tank.
Inspect The Toilet Tank
The Toilet tank is located behind the toilet seat and manages the flushing cycle. It consists of a flapper, a floating plastic ball, refiles tube, a water level adjustment rod, etc.
Any minor malfunctioning in this assembly causes a toilet overflow issue even if you do not flush your toilet.
Cause Of The Problem: Inspect the flush valve gasket for wear or tear. A flush valve gasket ensures an airtight sealing after the water of the tank is empty during a flush and again the refile tube fills the water tank to the required level. It is located on the surface of a toilet tank where the flapper rest.
Solution: Change the damaged flush valve gasket with the new one to solve the toilet overflowing issue even though nobody flushing it.
After applying the second troubleshooting guide, your toilet overflowing problem will be fixed, if the cause of the problem is a faulty flush valve gasket.
Backup Source Above The Toilet
Cause Of Problem: Sometimes other backup sources also cause toilet overflowing issues. These backup sources can be located at the height of the surface of your toilet. You can check the back source of your washing machine, shower, dishwasher, etc which are located on the same floor, where your toilet is located.
You need to clear the water of the other backup source to fix this issue. If other methods don’t work then this will definitely solve your toilet overflow problem, if the cause of overflow is the backup source.
Problem In Main Drain Or Sewer Line
After applying the two troubleshooting methods, if the problem remains the same then, the problem is not in your toilet. It is somewhere else.
Maybe the main drain pipe or sewer line has a blockage and it will create the issue. I would not advise you to do any troubleshooting in this area because this is a tough and risky task.
You have to immediately contact an expert technician to deal with the damaged drain pipe and sewer line.
I have seen many homeowners try to fix sewer lines’ faults on their own and make the situation worse than before.
Take The Help of Expert Professionals
This is always advisable to contact expert professionals in your area, to fix this issue, they had the expertise and special equipment to deal with external water blockage. They also follow proper safety instructions to deal with big leakage problems securely.
