"They installed a shut-off valve for the main water supply next to the water meter. The pipes were right up against the wall so I thought it might be a challenge for them, but they were in/out in less than 20 minutes and cleaned everything up like they weren't even there. Overall excellent job and would hire them for other work."

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."

Septic Tanks questions, answered by experts

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

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.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

Septic tanks last an average of around 30 years, depending on the type of tank system on your property. With proper maintenance, a concrete septic tank could last around 40 years, a plastic tank should last about 30 years, a fiberglass tank will last 25 to 30 years, and a steel tank lasts between 15 and 20 years. Ongoing pumping, maintenance, and septic tank inspections are the best things you can do to extend the life of your septic tank and identify potential issues as early as possible.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.
