More problems with my pink elephant. Once we got the water hooked up we found the septic tank to be full. Roto-rooter pumped the tank, but before we covered it back up, the tank filled up again within three days. We're not using any water yet, so I don't know where the water is coming from. Any plumbers out there, is it possible for water to come back up from the leech field? We're on a hill & haven't seen any rain in a while, so I don't think that is the problem...
