"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!"

"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!!"

"We were very fortunate that they were able to come quickly and replace our nonfunctioning septic pump promptly. They were professional and easy to communicate with. Given the emergency nature of the project, we did not get other bids so we can't say whether the price was reasonable, but they were upfront about the cost and stuck to their original estimate."

Septic Tanks questions, answered by experts

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Bladder and diaphragm well pressure tanks are usually pre-charged at the factory. Even so, it’s important to check the air pressure in the tank using a tire pressure gauge on the relief valve. The instruction manual usually calls for 28 psi. Use a hand pump to add more air or release some air from the tank to reach the desired number. Check the pressure periodically to see if you need to add more air to the tank.

Most septic tanks need to be emptied every 3 to 5 years, but it’s a good idea to monitor the fill levels of your septic tank all the time. You can do this by installing a pressure level sensor to detect the internal tank pressure, or by having a septic tank company perform an annual inspection to let you know when you’ll need to pump the tank.
