Sump and septic high-water alarms
High-water alarms, float switches and related septic or grinder controls in our catalog, grouped by words already in the product names (Wi-Fi, 12V, The Original, Level Sense, float switch, control panel). Official setup instructions stay with the manufacturer; this page is a retailer-style comparison of what we sell, not a copy of brand manuals.
If a septic or sump alarm is sounding, treat it as a high-water or pump-fail warning: check power, the float, and whether the pit or tank is actually high before resetting anything. Sewage tanks are a confined-space and gas hazard — do not enter a tank.
