Thanks for the input Flying Blue Eagle. Our septic has been pumped within the last three or four years. Last fall we had a plumber out for the same problems and seems like once before that . They always snake the drain from the septic into the house. We've tried the chemicals which helped temporarily. Now we're attempting to snake from outside. Good bit of bubbling , gurgling going on when we run water in tub to see if it'll drain. Also in toilet some too. House is thirty years old if that matters.
