I have been having a problem with all of the toilets bubbling. I have been able to fix the problem with a plunger but the problem keeps recurring. Today the toilets started bubbling and I was only running the washing machine. Again, the plunger fixed the problem. Last week while trying to plunger the toilet, the water backed up in the shower. I tried drain cleaner but I'm still have the same problem.
Is this a problem I can fix with a snake or should I get a plumber in to clean out the entire system.
