"Don't know if I'll have enough space to say all the wonderful things about Affordable Plumbing and Septic! We had an apparent lightening strike at our home on Lake Nehai in Keytesville. The septic tank pump/grinder (which carries waste water from the septic tank to the city sewer line up the hill) was fried. We couldn't use any water or flush toilets without the tank overflowing into the yard. Affordable's price was in line with other estimates, but their service was far better! They were prompt, professional and thorough. After the installation of the new pump/grinder, when it was discovered that the replacement pump/grinder didn't work, they determined that the electrical line that went to the old pump was also damaged. They called in an electrician who was able to replace the electrical line and we were up and running within 24 hours. Excellent service. Throughout the process, I was outside observing. All my (many) questions were answered with patience and good humor. The installation was not easily accomplished, but the expert installer knew how to overcome all the difficulties. If we ever have another problem, we will definitely call Affordable. We have even signed up to have them do an annual inspection and cleaning of the tank. The owner also talked with our insurance company to explain the damage to help us file our claim for the lightening strike. If you have a septic or plumbing problem, call Affordable!"

"We bought a house recently. The inspection report called for installation of an expansion tank and lengthened drip leg on the HW heater. Jamison Plumbing had installed the new HW tank several months before for the original home owner. Jason called the City of Liberty to determine the exact code requirements. He called back and agreed to the additional work at no charge. He was able to make the changes in a timely manner. His crew called to say they would be later than planned because of an unexpected delay at the preceding job site. We appreciated his willingness to finish the installation according to code and to cover the additional materials and time. It was a great way to be welcomed into a new community.

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

How deep your septic system needs to be into the ground depends on several factors. In extremely cold environments, the tank needs to rest below the maximum frost line, which can be up to six or eight feet deep. The standard burying depth for most systems is between a few inches and four feet below ground level. Depth can also depend on the slope of the landscaping and other property variables. 

Consider site conditions, soil type, required capacity, and system designs compatible with environmental protection regulations.

It is not normal to smell your septic outside and indicates a problem such as an unsealed manhole or access lid, a clogged septic line, a faulty vent stack, or the need for a septic tank pumping. If sewage is leaking from your septic system, it can be hazardous to you, your family, pets, and the surrounding environment. You can troubleshoot the issue yourself, or contact a septic tank pro who can resolve the issue quickly.

With proper maintenance, most types of septic systems—including mound, evapotranspiration, and constructed wetland systems—can last up to 40 years. To keep your system running as long as possible, follow basic septic tank upkeep guidelines, like pumping your septic tank every three to five years and only flushing human waste and toilet paper.
