"I put in a request for septic tank pumping and the first contact (from other company) was crazy high. A Affordable Septic gave a quote that was extremely reasonable and they surely live up to the name. Marty came out this morning; on time or even a bit early. He was extremely kind and helpful. I would definitely recommend this company for anyone needing septic service. I pray God's Blessings on this company and its employees. John 3:16"

"Our existing septic tank was only a few years old, but the associated drainfield was failing and required replacement. Due to a small lot, our options were limited; but rather than a huge and unsightly bottomless sand filter, we opted for a less obtrusive (but expensive) treatment unit and pumps along with the needed replaced drainfield. Cory was very helpful in explaining complex options and costs."

"Looked for someone to clean my drains outside and saw Grumpy's Drain Service - name drew me in, family owned with photo had me calling. We had someone out within a couple of hours and could not have been more pleased. Professional, knowledgeable, fast & efficient - could not have asked for better. Kinda reminded me of what I grew up with - down home trustworthiness, honesty, and didn't try to sell me something I didn't need. I will highly recommend to anyone and would use them again."

"M P Plumbing saved my day. I emailed my boss that I needed to take off to deal with plumbing problems. I proceeded to call five different plumbers. Could not be schedule until next week or two. So when I called M P Plumbing, I was elated they would come this afternoon. The plumber, Gene Mason did very professional work, was polite, and arrived today. Perfect results. Thank you.

"They put in new drains and a dry well for our driveway, carport, and front yard. When the first dry well wasn't large enough to hold all the runoff from a heavy storm, they came back and added a second for free. Excellent customer service, very responsive, good work."

Septic Tanks FAQs, answered by experts

Your drain field or leach field should be 1 to 3 feet under the ground. It will be a little shallower than the septic tank, although it can be the same depth or slightly deeper. The proper depth of the septic tank is up to 4 feet. It’s possible that your local regulatory agency requires a certain depth for your drain field.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Although air in your water lines won’t affect the overall quality of your water, it will lead to problems with your well water system if not addressed. Over time, too much air in your water lines can create blockages in your pipes, cause insufficient water flow to your taps and appliances, loosen pipes, and potentially damage important components of your well including your well pump and pressure tank. 

Cisterns can be used as septic tanks, but septic tanks can’t be used as cisterns. This is because cisterns need to meet FDA standards for drinking water, but septic tanks aren’t required to meet those standards since they are only used for wastewater.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
