Oh yes it’s good they could! One of DH’s first jobs here was installing and repairing septic systems. Worst problems were old people living alone who didn’t use enough water to flush stuff through. Ended up with pipes stuffed like sausages! He didn’t stay in that job for long!Last time it happened I was showering and the drain stopped. I tried plunging it and water rose in toilets. Next thing I checked was septic tank, it was fine so I knew the plug was inside house so I called the plumber. Despite the cost, I was glad they could clear it.
