It depends on what the builder has done for you. I installed my own dishwasher. You need electrical and a wye for the drain. My builder included the wye but I had to replace it because I purchased a Miele dishwasher. But you generally just need to cut the barb and hook up the drain hose. The builder did put in an electrical box with 14/2 romex. I terminated that into a receptacle under my sink. Most dishwashers just has bare wires and you just use a wire nut to connect power. Again, Miele, had a receptacle, so I plugged it in.silvergenesis wrote: ↑ From reading this thread, it sounds like the licensed plumber is more of a critical hire for this installation? We have a water line for the fridge and the dishwasher.
Should I be hiring an HVAC guy for the gas range?
You will need to drill a small hole on the floor to run the water line for your fridge. That was pretty straight forward for me.
The builder usually includes a range hood. I just disconnected their's and plugged mine in. My problem was, the power were on the opposite side and the wires barely reached.
The gas stove, this is the only thing I called a professional for. I looked at YouTube and it is actually easy to uncap the gas. All you need are two wrenches and some soapy water. But I didn't want to mess with gas. I called a guy and he charged me $150 to uncap it. I watched him do it, he did it in 5 minutes just like the YouTube video. To make things worse, he refused to connect the electrical (pilot light, oven). Said I had to call an electrician. I went to Home Depot, spent $40 for the gas stove 220 Volt cable and hooked it up myself in 10 minutes
The washer and dryer took me an hour to run the hoses for the dryer and connect the water.
It depends on how handy you are.
