The Red Alert LB50 high-water alarm from Septic Services monitors water level conditions in multiple applications including lift stations, alerting of high water levels before potential sewer backup into buildings. It has a warning light and 83 dBA audible alarm, along with an easily accessible three-position switch to change the alarm between normal operation mode, alarm silence mode and alarm testing mode. It can be used in residential sewage systems, dosing chambers, lift stations, cisterns, and other water and sewage systems that require high-water detection to prevent equipment damage or failure. It is easy to install by connecting the level control switch to terminal blocks and plugging the 7-foot power cord with grounded plug into a 115-volt outlet. 800/536-5564; www.septicserv.com/store.
