With over 25 years of experience in design, inspection, service and repair of septic systems, the founder of the Thermo-Disc has identified a deficiency that commonly causes septic systems to freeze and has created a solution. Our field testing has revealed that the majority of systems that were freezing were losing heat from the tank riser(s) and manhole cover(s). The Thermo-Disc has been designed to be installed as deep as practical in the riser, preferably to the tank lid, and provides an air-tight seal in most cases to prevent the cold air from dropping into the tank.
Keeps the heat in the tank and cold temperatures out.
Installs and removes in seconds for easy servicing.
Our standard device works with risers 23.5" to 24.25"
Leave Thermo-Disc installed all year.
