Hi...

We have 1 1/2 bath home. When you either use the shower or flush the toilet upstairs - the toilet in the half bath downstairs starts to overflow. We have tried over the counter measures - but nothing seems to help. Please advise.

Time for rodding the main, your blochage is after the basement bathroom. Yesterday we ran 120 feet of rod before we found the tree roots blocking the main to the city. We had the benefit of a SeeSnake which is a camera that can be run through the pipes.
