Do they all need to be plumed into the main line or is there some models that hook up to the sink like the dish washer does?

I use a garden hose splitter on the washer machine, but a T is good under the sink, I wouldnt use one of those piercing ones though

There are all kind of connectors or adapters, it can be connected to the main, the faucet, a hose Y at the washer inlet hose, or even use a pipe piercing T valve although I also do not like much the idea of piercing any pipe.
Depending on where you plan to install it the seller can supply your with any aqdaptor you may need.
