The Thermo-Disc is designed to insulate the manhole opening of a septic tank or pump tank. Many local units of goverment are now requiring that the manhole covers be at the surface for new systems and also requireing this for point of sale inspections. Having your manholes covers at the surface are neccasary for proper cleaning and inspection. If your manholes are at the surface and you live in a cold weather climate, your system could be at risk of freezing. If your manhole cover(s) are buried more than 1' below the ground surface or you live in an area that that typically does not have frost in the ground, then you will likely not benefit from installing a Thermo-Disc. The standard Thermo-Disc is designed to fit in a manhole riser that are between 23.5" and 23.25" in diameter and is not intended to replace a manhole cover or to be a secondary fall restraint.
