"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."

"The men at Ralston Excavating Inc. Wasted no time finding the cause of my overflowing septic tank (a crushed drain line) and replacing the line with new pipe. The service they provided was swift, professional and cost effective. I am very pleased with their work and highly recommend them to anyone needing help repairing or replacing a septic system."

"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."

"The provider was courteous and efficient, but I thought the charge was excessive. I could have replaced the toilet tank components myself for a fraction of the the cost, but I lacked the expertise to diagnose the problem. (The tank made intermittent, loud running-water noises when the toilet was not in use.)
His diagnosis of the foul smell near the front porch, however, was way off. Affixing the cap of the sewer vent did NOT to eradicate the odor -- because it was coming from a faulty gas meter 4 feet west of the sewer cleanout! Ultimately, it was the gas company that stifled the odor by repairing the meter -- and at no charge to the customer.

Septic Tanks FAQs, answered by experts

The size of your water well pressure tank is limited only by your budget and the amount of space you have to use. Larger tanks can hold more water, meaning your well pump will need to cycle less often. This can extend the life of both the pressure tank and your well pump. Larger tanks cost more and take up more room, though.

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.

With so much available information about the ecological effects of cesspools (and their general unpleasantness), it begs the question: Are cesspools legal? In short, sort of. Large-capacity cesspools that serve more than 20 people are completely illegal countrywide. Existing, smaller cesspools are generally allowed as long as they’re not actively polluting. However, new cesspools are illegal to build in all 50 states and Puerto Rico, and many states offer programs to help homeowners with the costs of updating cesspools to modern septic systems.

Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area’s reservoir and create aquifers, which then help to replenish your well.

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.
