"Last fall I had my septic tank pumped and found the leach field was failing. I called 12 places that put in septic system to do the work. Only one called back but was too busy. I filled out a computer help add for this service. Within 10 minutes John called me and was interested in doing it. The next afternoon he showed up and gave me a bit which was reasonable price. I already researched this. Couple months later we have a new leach field. Extremely happy with John and crew. Strongly recommend him. Thanks John."

Septic Tanks FAQs, answered by experts

A septic tank always has some amount of liquid in it—which should usually be 8 to 12 inches from the top of the tank. If the liquid level is higher than that or is overflowing the drainage pipe that leads out to the leach field, the tank may be too full and in need of pumping.

Your septic tank may be full or clogged if you notice household drains that are backed up, draining slowly, or gurgling; greener, lusher grass around the septic system; pooling water in your yard; or smelling sewage odors outdoors. You can contact a local septic tank pro to inspect your septic system and pump your tank.

While a traditional septic tank requires a leach field for wastewater disposal, it is possible to have a septic system without one. Some alternative systems, which are often used when there isn't enough space for a full-size leach field, include mound systems or sand filtration systems. In a conventional setup, the leach field is essential because it's where the wastewater goes after leaving the tank.

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.
