Septic Inspection in Mount Prospect, IL

Most septic problems are cheaper to fix when they are found early. A professional inspection in Mount Prospect checks how the system is built, how it is performing and whether anything is close to failing.

You might be under contract on a house or have owned your home for years. Either way, a local company that works across Cook County can give you a clear written picture of your system.

What a septic inspection covers

A full inspection usually starts with locating the tank and drain field and reviewing any records on file. The inspector opens the tank, checks the liquid level and sludge depth, and looks at the inlet and outlet baffles, the tank walls and the lid. Water may be run through the house to watch how the system handles flow. The drain field is checked for wet spots, odors and signs of surfacing water. Pump chambers, alarms and filters are tested if the system has them.

Quick checks versus complete inspections

Some inspections only confirm that drains run and nothing is obviously wrong. A complete inspection opens and measures the tank, examines the baffles and filter, checks pumps and alarms, and evaluates the drain field. When money is on the line, such as a home purchase, the complete version is usually worth it.

Good times to schedule an inspection

The most common reason people in Mount Prospect call for an inspection is a home sale. Other good times include before a renovation that adds water use and after heavy flooding. It also helps when you notice slow drains or odors, or when you move into a home with no records for the system. Regular inspections help you catch small problems before they turn into drain field replacements.

Reading a septic inspection report

The report should say where each part of the system is, how big the tank is and what it is made of, how full it was, and the condition of baffles, filter, lids and any pumps. It should describe how the drain field looked and list recommended repairs, with photos where possible.

Before the inspector arrives

Find the tank if you can, move vehicles off the drain field and make sure the inspector can reach the lid. Have records ready and a list of questions. If you are the buyer, ask the seller for permission and records well ahead of time. If the lid is deeply buried, ask whether digging is included or billed separately.

Questions to ask a septic inspector

Ask what their inspection includes, whether the tank will be opened, and whether pumping is part of it. Ask if they probe or test the drain field, how long the inspection takes and when you will get the report. Confirm licensing or certification required where you live and ask for a sample report so you know what to expect.

Mount Prospect averages about 39 inches of precipitation a year, and May is usually the wettest month.
