"Woody, Craig, and the team were great to work with and did an excellent job replacing my septic system. They were very responsive and communicated throughout the project. They were transparent about all pricing and honest. They did a great job with the install and the finish landscaping they did was more than I could have expected. I highly recommend them, they are busy for a good reason."

Septic Tanks questions, answered by experts

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

Yes! Toilet paper can be flushed if you use a septic tank. While unique toilet papers designed to be used with septic tanks are available, many people have no problem flushing regular toilet paper with a septic tank, so long as you don’t flush too much toilet paper all at once. Do not flush any type of baby wipes or bathroom wipes, even if they say “flushable.”

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.
