In May we had our septic tank pumped out. Everything has been fine, that was the first time it had been pumped in 9 years! Now, we are having some drain issues..... We have 2 bathrooms, and the bath tub seems to be the drian for the toilet? When you flush the toilet the bath tubs begin to fill and slowly drain. It takes a couple of hours for it to resolve, and for the past two days it has been occuring. I tried following some DIY boiling water, and once cooled a bit pouring it down the drains. It worked to resolve the bath tub drain at that time, but once I flushed the toilet it recurred. Please share any advice! Thanks, Rita
