I've got perplexing issue that I can't figure out.
I'm on a septic system -1k tank and evaporation field of 2) 60' runs. The system is 7 years old. Tank was pumped out last Spring and at the time of pumping was in very good shape -no over accumulation of sludge layer.
My vents are all installed as per plumbing codes and the system has worked perfectly until this latest issue.
What's happening is, when I flush the toilet everything flushes down just fine but just after the bowl clears I get a blow back, a small reverse pressure blast. Also, when the clothes washer is draining (which is in the bathroom and before the toilet) I get the same reverse pressure which, since the bowl is full of water now is a bubbling or gurgling in the bowl. No back ups and everything drains well otherwise.
I pulled my septic tank cover and my inlet is clear of any obstructions. My vents are all working fine and I have blockages in my sewer line.
I do have back-pressure valves on my vents to prevent septic gasses, but I've had them in place since the beginning and everything has been fine till now.
I can stop the problem by taking the cover off of my outside cleanout. When I remove it while the washer is draining or toilet flushing I get a blast of air releasing.
