We bought a house in June that was built in 1976. Had the tank pumped because nobody could tell us when it was done last. Good thing the lady that sold us her parent's home knew where the tank was, 'cause we never would have found it otherwise. It was under a trapdoor in the wooden deck! Anyway, I figured I was in troube when the honeywagon guy opened it up and said "Hmmmmm, I never saw anything like this before!" It's a big ole metal tank with an electric pump in it! Anybody ever heard of such? And that metal tank is 30 years old. I guess my question is, how long do I have to save up for a new one, 'cause someday it's gonna leak. Probably sooner than later. And what about that pump? Septic guy said the tank had no baffles or filters. He also said it wasn't full and hadn't backed up into the drain field. I did read the whole family the five dollar lecture about what could go in there. We only use septic approved tp, no liquid fabric softener, no grease, food, feminine supplies in the toilet, short showers, etc. But there are a lot of us...... 6 adults and a 2 y/o. Any other septic saver tips?
