We called Mr. Mueller to come and check out our septic tank. We had never had any trouble but neighbors were beginning to have their tanks pumped to avoid trouble. We have a small family but thought that we ought to get the tank pumped because we were just a little past the recommended time frame. Mr. Mueller did an excellent job. He was able to reach our tank without bringing his heavy truck onto our lawn or cement driveway. We were in time before experiencing any problems. Mr. Mueller also gave us recommendations on how to keep our tank healthy by putting in a package of yeast every 3 months to keep healthy bacteria in our septic tank. We would definitely call him again for assistance.
