"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 specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"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

Recognizing signs of a failing septic system is crucial to prevent costly damage and health hazards. Foul odors in and around your home, slow drainage in sinks and toilets, or gurgling noises in plumbing fixtures can indicate problems with drainage. Lush, green patches of grass near the drain field or wastewater pooling on the ground are alarming signs that may indicate a leak in the system. If you notice any of these symptoms, it's vital to address them promptly to avoid more extensive and expensive issues.

Yes, it is possible to pump a septic tank too frequently. The ideal pumping schedule varies based on the tank's capacity, household size, and water usage. Pumping the septic tank more often than recommended can cause the beneficial bacteria to leach into the drain field, leading to an imbalance and a build-up of solid waste.

When your septic system is failing, you’ll probably smell it. Common signs of a septic system failure include sewage odors in the home or around the yard, flooding in the yard above the septic tank or in the leach field, and wastewater or even raw sewage backing up into your home’s drains.

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.
