About Us

PermAlert ESP, a division of Perma-Pipe Inc., manufactures and supplies leak detection/location systems that help keep mission critical facilities online and in production. PermAlert was established in the 1980's to provide high quality water, chemical, and fuel leak detection systems for use under raised floors, attached to single wall pipes, AST’s and UST’s, double wall piping, trenches, and trays. Permalert offers several product lines to suit a variety of applications.

The PAL-AT^® system monitors a coaxial cable for faults (leaks, breaks, shorts) using time domain reflectometry.  The coaxial cable is installed in subfloors, under piping and equipment, along single wall piping, inside trenches and trays, in the interstitial space of contained piping systems, and other areas where liquid leakage may occur. 

The LiquidWatch^® system monitors point locations and can be configured to monitor up to 64 locations with reusable hydrocarbon probes, water probes, and float switches. 

The FluidWatch^® system has been engineered to monitor small areas for water leaks.  Typical applications are unmanned equipment rooms, small raised floor areas, and small tanks.

PermAlert products are sold to a broad customer base through a network of local representatives and dealerships worldwide. Our leak detection manufacturing and corporate office are located in Niles, IL.
