Backflow preventer for toilet and sewer ovetflow

[Art]

Hi everyone. I have a toilet in my garage and when my sewage line gets clogged it overflows. Do they make a toilet or something for the toilet that can be installed to prevent the sewer water coming back up and out the toilet any help would be great.

Yes it's called a back water valve,yo would have to dig up that line and install it

You'll want a plumber to do the work, but you can do the excavation

Thanks guys for the responses. I saw that and was hoping there was an option that didnt require breaking up the concrete. Like something already built into the toilet or a special flange
