Residential and business water treatment systems. Water softeners, UV lights. We will analyze your water for contaminants such as chlorine, low pH, iron, bacteria, and devise a system to suit your needs. Treat your water from the source, as it enters your home, so whether you are drinking it, cooking with it or bathing in it, your water is pure.
"The process was quick and easy. I just provided a water sample. It was determined that I had high levels of chlorine in our drinking water. I was able to solve my water problems with only one filter. Why did I wait years to have this done? Now I can be confident that our water is safe. Highly recommended."

"We had this plumber here last February 2020 and we were pleased with him. He said he could redo the plumbing so it would be neater as the guys that had put in the water neutralizer had made quite a menagerie of pipes and etc. He also told us that it appeared that the pressure tank had a small leak and we should think about getting one in advance so we could replace it when needed. We called him for another repair this December 2021 and left messages on 12/10, 12/11 and 12/13 at the 715-453-8240 and he did not return the calls. Thinking that the number may have changed I searched online and found a cell number which I called and got an answer. I told him we had 3 leaks on the 13th of December and he said he couldn't come until the 17th so we limped along until then. When he got here he seemed crabby, he didn't answer my questions(some I asked 3 times) and he did the repairs which included two pipe leaks, a leaking pressure switch and he hooked up the new pressure tank. After they left we ran the water and the pump was short cycling. Come to find out he never set the pressure switch correctly so it was set at 40/30 so the pump was cycling off and on continuously when we ran the water. I should've stopped payment on the check. We adjusted the pressure switch and corrected the pressure tank as well. Also, he didn't have any 1 inch pipe so I found a piece of new 1 inch pipe that we had, then he needed a 1 inch to 3/4 inch tee that he didn't have so he had to go to Merrill to get that, we're in Gleason I was thinking, "what do you have in that fancy truck if you don't have these parts?" Then he charged us for the time it took for him to go to Merrill and back too yet. Very disappointed in his work. Will not be calling him again."

FAQs for septic tank service projects in Mercer, WI
The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
