bathtub trouble
I live in an older single wide mobile home. Three days ago when I drained the bathtub the toilet started gurgling. Later when I flused the toilet the water rose to almost to overflowing and slowly went down. Now when ever I let water out anywhere in the house I can hear gurgling in both toilets and the vanity sink. Any ideas? Thanks in advance.
Sounds like there could be an issue with your vent(s). If a vent in your bathroom is plugged, every time you drain a significant amount of water from somewhere, it would form a suction and literally suck the water out of the bathtub drain trap, or toilet.
This is where I would start - have someone check the vent's up on the roof. The simple way is just to have someone by the vent while you run water to see if they can hear it. If you can't figure it out, call Roto-Rooter or a professional plumber...
Good Luck.
