Bathtub with Septic Tank takes HOURS to drain
A year ago, I purchased a house that has a septic tank. We've had to have Roto-Rooter come out once to flush the lines because the toilet kept backing up (no problems with the tub). The Roto-Guy told us that we would need to have the tank pumped soon and also add the septic treatment regularly.
We haven't had a problem until recently: the tub takes literally up to 12 hours to drain! The toilet is flushing fine and the bathroom and kitchen sinks are draining well. I used a septic-safe drain opener, but to no avail. I can't afford to pump the septic tank right now. Any other low-cost suggestions or ultimate advice?
