The name says it all – United 493 is your solution to keep lift stations maintained and running cleanly. This is a Solar Solvent formulation that emulsifies fats, oils, and grease (F.O.G.) in lift stations. It floats on top of the water in the lift station and as water passes through, it catches and emulsifies F.O.G. to keep the lift station running cleanly and efficiently. It is non-toxic, non-caustic and non-acid.
