The trouble seems to be just in the bathroom on the main floor.
First it was flush the toilet sometimes it would go sometimes clog... then plunge and away it went I would boil pots of hot water and pour it and dish soap down the toilet. Next the bathtub wouldn't drain when I plunged it the toilet would gurgle. Bought liquid plumber put it down the drain and it slowly drained. Then flushed the toilet and it gurgled up into the bathtub an not a little bit but a lot. Went to brush my teeth in the sink... same thing up into the tub... Any ideas at all... Help!!
Oh and we have septic that was cleaned out about 3 months ago so I cannot see that being a problem!
Thanks!

You have a blockage downstream from the tub and toilet that must be snaked.
This can be addressed in one of three ways.
1_ Pull the toilet and snake from there.
2- Snake from the tub overflow **or**
3-Snake from the lavatory roof vent. If you need instructions on any of these click on back, Good luck, Tom
