We have a septic tank (obviously underground) that sits about 20 feet from our back bedroom. Our back bedroom smells horribly!! What could the problem be? We have a B-Dry sump pump underneath the house and the verizon people have hit the drainage pump to the system and therefore probably causing the sump pump to backup. We had the septic company come out and they felt like everything was ok with the septic tank. The sump pump is still working but the drainage pipe drains into the hole that we dug to discover the break in the drainage line. We have just gotten a ton of rain and the hole that was dug is full of 2 feet of water. So, the water in the hole drains back into the sump pump system, and when the sump pump flushes, the water under the house gets drained into the hole. By the way, this whole is also 5 feet from this back bedroom. WHAT COULD THE PROBLEM BE??????
10 points!
by the way no smell under house and no smell in other bathrooms

You have or had a drain leak.Pump out and dry the hole to see if it clears up.If that doesn’t fix it then find the leak.Good luck on the digging.I don’t envy you.
