The Sump Alarm weatherproof high-water alarm is designed for simple and fast installation with no onsite wiring for septic tanks, lift stations and outdoor pump stations. Simply position the float switch, mount the head unit and plug into an outlet. It has a 1-inch LED pilot light visible from a distance with an integrated 90 dB alarm. It is available with a mercury-free float and cords in 10-, 16-, 33- and 100-foot lengths. This allows the alarm to be positioned near a secondary power source in a highly visible area, ideal for line-of-site installations. Units are available in 120 or 220 volt and are preassembled and suitable for extreme temperatures. Low-level models are also available. 314/787-8059; www.sumpalarm.com.
