"John showed up and started working right away. He assessed the system and knew immediately and exactly what was going on. Our septic system had not been cleaned out properly the past several times VIA other companies. Of the 500gal first tank less than 200gal was available to be used as the rest was totally solid. He and his co-worker dug up the lid and slid it open to do a SERIOUS clean out. I saw what was in there and no wonder it did not work properly! He took his time and cleaned every last thing out of the system! I mean EVERYTHING! When he was done you could see the walls and the bottom. Super friendly, super helpful and explained everything and more. I will never call another service out; these are my go-to guys!!!"

"Andrew was great. We bought an older home with a conventional tank that hadn't been maintained in a very long time. He came out within a few hours of calling him on Christmas Eve-Eve.. His price was competitive, he was very knowledgeable and even humored my teens and explained everything as they stood over him watching the process (we've never had a septic tank before!). Have already recommended to neighbors."

"They did a good job and had to search for the tank and field pipes , my only criticism would be if you are going to dig in a garden then why not lift the grass as a sod , as it would be easy to replace after and would leave a neater ,faster healing job ."

Septic Tanks FAQs, answered by experts

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.

Unlike an urban sewer system that runs wastewater into a central drainage system, septic tanks are a house-by-house system. They are the ultimate destination for all your house’s wastewater—from bathtubs, showers, sinks, toilets, and washing machines. Wastewater flows into a tank buried in the ground outside your home, and then water runs from the tank to a drainage field using sloped pipes.

To prevent septic tank problems, save on repair costs, and keep your home running smoothly, it's essential to perform regular maintenance. Have your septic system inspected by a professional every one to three years, or annually if possible, to spot potential issues before they develop. You should also have your tank pumped every three to five years, or more frequently if recommended by a professional based on your household's usage. Additionally, be mindful of what goes into your system. Avoid flushing items like paper towels, wet wipes, and feminine hygiene products. Do not dispose of other inappropriate substances, and try to avoid excessive water usage at a single time.

Never use Drano on blocked toilets. You can end up with a ghastly leak because the chemicals eat away at the glue that holds pipes together just as effectively as they do with clogs. Drano is known for being particularly rough on toilets, which is why some plumbers actually dislike the product. 

While not strictly necessary for your septic system to operate, septic tank risers are a highly beneficial and wise choice for homeowners. They provide easy access to your tank, which makes regular maintenance, inspections, and addressing issues significantly easier and less labor-intensive. By eliminating the need for repeated excavation to locate the tank, risers can save you money, labor, and energy in the long run. This easy access allows you to proactively manage your septic system, addressing potential problems before they become costly and ensuring the system's longevity. Additionally, some local regulations may require risers, and installing them can help you avoid potential fines or penalties.
