Water drains from the toilet to shower in main bathroom then goes to the second bathroom and comes out the bottom of the toilet. I live in a doublewide so I checked my septic tank and it maybe a little bit over ¾ full. Pipe has a slow leak coming into septic tank. I about a 25ft snake and went in the septic pipe leading into the house. And then I snakes the vents on the roof and in side the whole house. But water still comes out from the bottom of the toilet

If water is coming out under toilet, need to remove toilet and replace wax seal.

I have a different take then Chuck, Wax seals are there to allow a flush to pass but not to contain standing water caused by a back up. However Chucks correct when he says the toilet must come up and the seal replaced. You have a blockage downstream from that toilet, Pull t and snake the drain line. Replace the wax seal when you reinstall. Good luck, Tom
