I live in Michigan. We have been slammed with snow, that is just now beginning to melt.
Yesterday I noticed, when I wash my basement toilet overflows and lets in a sewer smell:eek: . Then today when I gave my infant a bath and drained the water out the basement toilet overflowed again with the same stinky smell.
That half-bath is not in use and the water valves are shut off because of previous overflowing issues.
Help!!

Hall21232000 - You did not say if you are on a septic tank or on the city sewer but still it sounds like you have a swere line stopping up on you, #1 If you were on a septic tank ,I would almost guess that the tank was full, from all the rain and snow youal have had. I've seen it wher a septic tank was pumoed out the afternoonbefor and by the next morning at 7:00am it was plumb full from rain water standing in their yard.the ground was so saturerated forom the rainI'D call a plumber to come out and run a snake down the sewer lineafter he's done flush the toilet at four timesI hope this helps ,if it bdoes rate my answer below Good Luck& GOD BLESS

I don't know exactly, but I believe we have a city sewer. I know we have city water. My house is old, 1930ish. If I brought some septic cleaner, would that help or harm? I brought some professional strength declogger and it ate through my old pipes, don't want this to happen again.

hall21232000- You have to really watch some of that prof. stuff and if you call a plumber out to work on your sewer ( LRT HIM KNOW WHAT KINDS OF STUFF YOU HAVE PUT DOWN YOUR SEWER> this stuff is dangers they are susposed to sell it only to licensed plumbers due to part of what you have seen and it is dangers to humans also , so please be causious and safe . Now you can be on city water but still live in the county where you have to have a septic tank Since your house is that old ,do you know if any of the sewer lines have been replaced, you probably have (ORANGEBURG - pipe roots can grow right threw them and get inside of pipe and plug it up finlly completely. I don't think you have the old 2' long sections of it ) they were real bad with growing inside of them and compeletely plug them up also grow in threw the joints. So that leaves cast iron , it runs from 1 1/2 " up The main sewers in your house IF cast will be ! 1/2 '" up to $' . A plumber can rod it out but one with a roto rooter can do a better job but as fast as they can grow inside of pipe you would probably have to clean them out 2 or 3 times a year .
Check with a plumber and get a written quote on cost, you should not have to pay for them to come out and give you a estm. I never did and a lot of others I know don't Good Luck & GOD BLESS ::: F.B.E.
