"Modern came out quickly and pumped our septic tanks, giving us a discount for having 2 tanks on our property. They identified baffle wall issues with both tanks and recommended 2 septic repair companies (one which we used). Very fast and courteous employees."

"Aaron at A1 septic is a great guy. I really appreciate that they actually answer the phone. So many other companies have you leave a message and never return a call. A1 Septic was able to schedule service right away, was on time, and were pleasant and respectful to work with. They were able to locate my septic tank without a problem and left the site clean. I would highly recommend them to anyone and will definitely use them again."

"We could not be happier with our new bathroom, thanks to McCormick! Khaled was knowledgeable and really took the time to understand our style preferences. The whole team was great about keeping the workspace tidy, which we appreciated. Now, we have a bathroom that feels luxurious and welcoming. Highly satisfied with their work!"

"Great for me. Not so good for Roto-Rooter. Work took over three hours to fix problem but Matt stuck to it and go the job done with no increase in estimated cost. Very professional and thorough. Ran a camera through all pipes and explained what the problem area was. Highly recommend."

"They had to come out 4 times. The first water heater started leaking after 6 months. It was replaced. The second water heater also started leaking after 6 months. I contacted the manufacturer and they recommended a thermal expansion tank be installed. It was not installed the first or second time the water heaters were installed. I did have to pay a re installation fee. I picked up the 3rd water heater myself and they gave me natural gas water heater instead of propane. The fourth attempt they finally got it right and so far the water heater has worked after 7 months. The guy was very responsive as far as my calls and issues. He came out whenever I needed. Unfortunately, the entire experience was just a train wreck."

"Extremely professional, responsive and knowledgeable of the current code. Rewired my entire 112 year old home. The project was easily adapted to my preferences. Mike was not pushy, and worked well with other trades on site as well as through the planning process. The best part, is he did exactly what he said he would do, when he said he would complete it, at the promised price! He is an American veteran, that works quietly and cleans up well afterwords with no exceptions, no excuses! Prompt, reliable, and"

Septic Tanks FAQs, answered by experts

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

The efficacy of a drain field depends on a wide variety of factors, though a well-maintained one can last as long as 40 or 50 years. Of the different types of septic tanks on the market, concrete and plastic tanks tend to last the longest—upwards of 40 years if they’re pumped regularly—while steel tanks have a tendency to rust over time and may need to be replaced after 15 or 20 years.

There should be a red button or an on/off switch on or in your box. Press the button or flip the switch, then turn it back on by doing the same action again. If this doesn’t work, reset the breakers inside the box by flipping them off and back on again. After this, your alarm should stay off if there’s nothing wrong with your system. However, if the alarm is still sounding and there’s still a red light on, it’s time to call a pro for a diagnosis.
