Hi I have a question. We have a modular home on 2 1/2 acres with a well and septic system. We notice that when we run the washeing machine the toils sometimes make a bubbling noise. Our master bath is on the other side of the wall from the laundry room. Also last time we had a heavy rain we noticed the liquid from septic came up through the access door of septic. What would be causing the bubbling in toilets and the septic liquid coming out during heavy rains, would that be causing the bubbling?
