"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

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

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.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”
