I live in a rural mobile home, and believe I have a septic system problem. I don’t know the proper terminology, but we have a pit and then a pipe that goes out to a drain field. Anyway, my grandmother lived here for two years, then the house was empty for 10 years, and I have lived in it the past 3. I don’t believe the septic has been pumped out in all that time. My problem is that every faucet in the house and out, smells like rotten eggs. I have tried drain cleaners, with no result. Another site led me to believe its a septic problem. Do I need to pump out the system or will the natural enzyme product they were trying to sell me work?
