"Marcus came over the day after I requested the quotes (quotes requested Sunday, he came Monday.) He assessed the situation and explained options and pricing. He very willingly attempted the lower cost option first, even though we had doubts it would work. He told if it did not work and we had to go to the higher cost option, I would only be charged for that, not both. We did have to go to that option and he was able to clear the clog from my sewer line. He then inspected with a camera and showed me that there were several roots intruding on the line. He recommended repeating the process with a nozzle designed to remove these. He did not have that on his truck, so another visit was scheduled for today with a different tech. This was also successful and it was clear from the camera inspection at the end that the roots were gone. I was expected a horrible mess from this process, and was very happy that both operations were completed with minimal additional sludge in my basement."

"Josh was fantastic to work with. Bill did my previous inspection in 2017 so I knew I had to call again. Josh was VERY thorough with his inspection. Pointed out every item he felt needed mentioning which was extremely helpful! The septic inspection was fantastic as well. Very neat and clean dig locations as well as information and recommendations moving forward. All in all I would highly recommend MCI to anyone anywhere! Extremely pleased with the results!"

"Troy and Cyr septic did a great job. I found Troy to be honest, straight forward and willing to get right in there and get the job done. I was most impressed that Troy was willing to drop everything he was doing when I contacted him on Sunday. He showed up, assessed the situation and created a plan of action and quote. All the prep work was done on Monday, then we had to wait for a pumping service which took a few days. Troy was back that afternoon after the tank was pumped to finish the job. In the end Troy collected exactly what he quoted for the job and my tank was repaired"

"They came out first to find the septic tank and then would have to come back with the pump truck to pump it. After utilizing the camera mechanism to locate the tank, we were advised that pumping wasn't really needed yet. They could easily have led us to believe it needed to be done, but they chose to be honest and save us the added cost. Honesty & integrity, i like that in a service provider!"

"Doug (owner) and Brandon arrived right as scheduled (prior communication to confirm appointment was excellent). After a lot of digging they were able to locate tank/lid. Very professional and polite to deal with. Extremely reasonable pricing, both were incredibly nice to deal with. Would highly recommend McAtee to anyone. Thanks again!!"

Septic Tanks questions, 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.

An outdoor water valve typically has a round or oval handle that you can turn to control the water flow. It may be located in a protective box or pit near the property line, where the main water line connects to your house.

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.

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.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.
