Install On Existing Connections
When the drain, space, and power suit the unit, we install it, connect the drain and dishwasher, and test it.
GARBAGE DISPOSAL / INSTALLATION
A NEW DISPOSAL, CONNECTED RIGHT.
Installing a garbage disposal involves the sink opening, the drain, the dishwasher connection if there is one, and a safe electrical connection. We check all of it before the unit goes in.
GARBAGE DISPOSAL SERVICES / SPECIALTY SERVICE

UNDERSTAND THE ISSUE
A disposal mounts to the sink flange and connects to the drain, and often to the dishwasher drain as well. The trap and drain height under the sink need to work with the unit’s outlet, and the electrical connection must be safe and suited to the appliance. If the home is on a septic system, check with your septic professional before adding a disposal, since not every system is suited to one.
WHAT WE'LL CHECK
We look at the sink opening, cabinet space, drain height and trap, dishwasher drain, and the available electrical connection. We explain what the installation includes, whether any drain or connection changes are needed, and anything that should be handled by a separate trade.
