Everyday habits that protect your system

Your septic system handles everything that goes down the drains in your Mount Prospect home. Using less water, spacing out loads of laundry and skipping the garbage disposal all reduce the load. Keep the area over the drain field planted in grass, and know where your tank lid is so pumping visits are quick. Records of past service make future repairs and home sales easier.

After heavy rain, check your Mount Prospect system

Wet seasons put extra pressure on septic systems around Mount Prospect. If drains run slower after a storm or the ground over the field turns soft, the soil may be saturated. Limit water use for a day and watch whether it recovers. Trouble that persists after the ground dries out needs an inspection.

Finding the right local company

Local experience matters with septic work, because soil, rules and common system types change from county to county. A company that works around Mount Prospect and Prospect Heights, Des Plaines, Arlington Heights will know what the Cook County health department requires and what tends to go wrong on local properties.
