Nope. Pouring liquid grease down a drain with hot soapy water does not prevent fats, oils, and grease (FOG) nor does it eliminate the need for a grease interceptor. The grease will cool and harden causing blockages and overflows.
Enzymes, chemicals, or other products designed to emulsify or liquefy grease are not acceptable substitutes for a grease interceptor. Garbage disposals are not acceptable substitutes, as they do not remove grease.
