All units must schedule backflow device testing of their fire sprinkler system to comply with DuPage County Public Works ordinance. This yearly mandatory test and certification is required on all systems by the county. All payments are the responsibility of the home owner.
Residents are responsible for individual testing, but Maple Hollow board would like to help by arranging for group testing at a discounted rate.
Fill out this 2-minute survey (or see below) to coordinate bulk testing at a discounted rate.
If the below dates do not work, please still fill in the survey. If more dates or times open up, you will be contacted.
