We have a triwide mobile home with 2 bathrooms. The guest bathroom has a urine smell and has had it for quite a while now. It's clean and the only thing I can think of is the vent pipe on the roof is clogged. How can I go about clearing it without damaging anything Also, I hear the toilet kind of gurgle throughout the day as well as slow flushes.

A gurgle indicates a blocked vent. Snake out the bathroom roof vent. Good luck, Tom

Tom's correct as usual but I think you would smell more than urine. The gurgle means blocked vent, urine smell means my grand son is visiting me, at least in my house.
