"On Wednesday morning I woke up to water in my basement due to a leaky gauge. I called Agua Well and Pump and they told me they could try to get out that day but for sure the next day. The woman that answered the phone gave me her cell phone number so I could forward a video of the problem. About 4 hours later, I received a call that they would be at my house in 5 - 10 minutes. I left work and by the time I got home, they were there. The service technician, Chad explained everything to me and gave me his recommendation to replace the pressure tank due to the gauge leaking and the age of my tank. I went back to work and the job was completed by the time I got done for the day. Excellent communication and customer service!"

Master Plumber's license # 224991. Bonded and insured. No sub-contractors are used at Mike Ingrilli Plumbing; all employees are full-time and work directly for Mike.

"Don’t ever use this company! First, they overcharge! And, they will not come back and fix something they installed that should be warranted. We used him several times and every time they had to go back and fix what they installed. They wanted to charge us for the work that they Installed incorrectly. We are still dealing with this issue a year later. Obviously, we stopped using Ingrilli and we are with a more professional, reliable, plumbing company. Save yourself the headache and stress because there are plenty of other, qualified plumbing companies out there to use and Mike Ingrilli is not one of them! He is very rude and unprofessional!"

"The remodeler I am working with had recommended Riverside and spoke very highly of their services... so I called for help with my 2 water heaters that were both not working. I am so appreciative of the quick response and the quick fix. I had questions too about how those were configured and everything was explained to me.

FAQs for septic system installation and replacement projects in Milwaukee, WI

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
