94WM_with_CapThe MainGuard #94WM Sampling Station is designed specifically for collecting bacteriological samples at a designated point directly from the main water line. The #94WM provides a 24/7 designated sampling site to retrieve samples at any time versus sampling from homes and businesses. Sampling stations have been shown to lower false positives, speed collection times, and lower liability concerns. Sampling Stations have been approved for use by the EPA’s Total Coliform Rule.
The MainGuard #94WM is a non-draining unit that comes standard with an all brass and stainless steel waterway and fits into a standard 5/8” x ¾” existing meter box. The unique threaded valve connects easily to the sampling rod and eliminates stress on the meter setter as with other quick-disconnect models. The sampling rod (sold separately) includes a multi-directional swivel blow-off head and separate sampling bibb. Certified to NSF/ANSI 372
