Temporarily sealing toilet drain

My grand daughter just moved out of my second house. I want to turn off water for months or longer. How do I seal toilet to stop sewer gas from entering house with out pulling toilet and plugging pipe under toilet. House might have to be put back into use at a moments notice.

We always winterized our cottage by putting antifreeze in the toilet water and the sinks. I would use and RV or Boat antifreeze just poured in to the drains and bowl. Should not harm the toilet or sinks.

I would do exactly what Czizzi mentioned. Drain the water lines and dump some RV antifreeze into the toilet and sink traps. When you're ready to turn everything back on, just turn on the water and run the faucets for a few minutes.

Antifreeze dries out in less than a month then sewer gas back into house, I was hoping someone had a better, longer term solution. I have use the antifreeze but did not want to have to keep adding it for months

Antifreeze does not evaporate.

Rv antifreeze is not the same as the antifreeze used in engine radiators. Rv antifreeze lasts all winter when used in the plumbing system of an rv. Will work just fine for your application.

I would still recommend RV antifreeze. But if you are stuck on another solution, an inflatable test plug can work. I assume a 3" one would work well for a toilet, though honestly I've never tried. Inflate with a bike pump.

If it's only going to be vacant for a month or two, you could skip the antifreeze altogether and put saran wrap over the bowl to prevent evaporation of the water, but use the antifreeze, it's better and as XSPLR says, RV antifreeze will not evaporate.

Agreed. RV or plumping antifreeze. Usually red/pink in colour. Not to be confused with engine coolant/antifreeze. Been using the RV stuff for 20 years when we winterize our summer home.

After you dump the antifreeze in, put plastic wrap over the bowl.
