"After trying to get numerous sewer and water companies to even come out so I could explain the problem I was having, and get an estimate, I finally got a response from Lincoln Sewers.  Phil from Lincoln Sewers first came out in April 2015 and ran a camera down the sewer line.  It appeared as if the sewer line had become disconnected where it comes out of the house.  During heavy torrential rains the sewers were filling up and actually flowing back into the original somewhat of a half crock overhead sewer system that was already in my house when I bought it 12 years earlier.  The water was flowing heavily back into the sump and ejector pump pits during torrential rains.  After doing my own research on what a true overhead sewer system is, Lincoln Sewers did the new sewer system which has the main pipe going out the side of the basement wall (which is a true overhead sewer system).  Overall, everything seems to have been done well.  No leaks in the pipes, and water from the house seems to be flowing just fine out to the sewer system.  Lincoln Sewers got the permit, and the city inspector from Chicago was out to inspect their work on July 6th.  The inspector informed me the work being performed was up to code.  I'll have to wait and see how the system holds up during torrential rains, but so far everything seems good.  Overall clean-up at the end of the job by the employees was good, and pretty much everyone I've either dealt with personally or on the phone from Lincoln Sewers has been helpful and professional including, Phil, Robert, Doug, and Janet.  I had contacted multiple sewer and water companies in an attempt to get more estimates, but only one other company gave me an actual written estimate and it was almost double of what Lincoln Sewers charged me.  I would recommend Lincoln Sewers to other customers.  At this time I have no complaints about this company.

"We just bought a house on a private well and started noticing rust stains and a foul odor right away. The house came with an old softener, but it didn't seem to be working anymore. We got a few quotes for a system that would treat well water and decided to use Chicago Water Pros. Their tech was on time, very professional and knowledgeable. The price was very reasonable compared to the other quotes that we got, and they had a way better warranty and money back guarantee than anyone else by far. We bought a tank for iron treatment and a softener. The guy that came out to test our water and do the quote was there for the installation and came back out to re-test the water and make sure everything was working properly a few days after the install as well. We couldn't be happier with the water and the great service and price that we got. I'd recommend them to anyone!"

"The awesomeness started within a couple hours of purchasing my deal. Matt reached out to clarify a misprint in the deal, and assure I still wanted to go through with the deal. He was able to to schedule me at a time that worked with my busy schedule.
Darryl and Mike arrived right on time, first thing in the morning. I had originally purchased a hot water tank replacement deal. During the old tank removal, it was discovered that my ejector pump was not working. The crew was equipped to replace that at a reasonable price as well. They worked quick and professionally and had all the work completed in a timely manner. They made sure to have tarps available to protect my floors when moving the tanks in and out. The crew had such pleasant personalities, and I could tell they enjoyed what they were doing.
I highly recommend M&E Plumbing for any work you may need!!

"I think their coverage is a little spotty. You have to look at the document very carefully. It seems random to me. I reported a problem once and once I used the word "septic" they wouldn't cover it. Another time I didn't say it and then they covered it. You have to be really careful about how you phrase things."

Septic Tanks FAQs, answered by experts

You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

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 physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

According to the Environmental Protection Agency (EPA), septic tanks must be located a decent distance from places subject to flooding or surface ponding. Additionally, septic tanks should be installed on level ground so that the waste can properly settle in the tank. Most tanks are located 10 to 20 feet away from the home. More specific requirements vary by location, so call a local septic pro or your local health department for more information.
