"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

Most homeowners know there’s a septic system problem when they can smell one. However, this isn’t exactly a scientific deduction method. Consider some of the other signs: standing water or constantly damp earth in the drainage area, toilets and sinks that won’t drain or frequently back up, and loud plumbing. You really need to be on top of routine maintenance with septic systems in order to avoid such unpleasant symptoms of a septic issue. 

Over time, your septic tank can accumulate a buildup of sludge at the bottom of the tank. If left unpumped and uncleaned, the sludge will back up into your pipes and home, causing failure and extensive (and smelly) damage. Repairs to your septic system can be costly, which is why regular maintenance is required. It takes about 30 minutes to pump a septic tank that’s 1,250 gallons or less or 1 hour for larger varieties.

Several things can ruin a septic tank over time, including dumping harsh chemicals (like bleach and ammonia), pesticides, and paint thinners down your drain because they can kill the bacteria in your septic tank. You should also make sure to only flush waste and toilet paper in your toilet—otherwise, you could clog your system.

Yes. A metal detector is one of the quickest and easiest ways to find your septic tank. However, metal detectors can be too expensive (costing upward of $300 in some cases), and not everyone has a metal detector just lying around. If that’s the case for you, you can also take a long metal rod and poke it into the ground at regular intervals until you hit something—likely your septic tank lid.

The lifespan of your well casing depends mainly on the material it’s made from. Stainless steel and galvanized steel casings are designed to withstand the pressures and environment of deep-water wells but are susceptible to corrosion. Most steel casings last from 20 to 35 years, on average. PVC casing is highly durable and, if used correctly, can last up to 50 years.
