He said it takes about 30 minutes. If you have an existing disposer, it s really just a matter or twisting the old one, unplugging it and connecting the new one, he said. The only tool you ll need to perform this handy feat is a screwdriver. Rouleau, who said he shuns electrical work, said most people will have no problem connecting the cord to the disposal. A home owner can do that as long as they re careful to make nice, tight connections, he said.
Most power cords come with diagrammed instructions.
Rouleau said he advises against installing a garbage disposal where none previously existed. A first-time installation may involve making adaptations to existing plumbing, hooking the disposal to a dishwasher, and electrical work, such as installing an outlet and wall switch. Disposals should be on their own electrical circuit, Rouleau said. In that case, maybe you want to give it off to a plumber or a contractor, he said. That price does not include the cost of a disposal.
