I mounted the unit under the sink following the directions and mounted the included faucet as well.. It also came with a tee that hooks up past the DI
part and has a hose past it.. When you turn on the DI
part it comes out of the hose.. I just fill 5gal buckets at a time and xfer it into my larger 30gal can that resides on my patio.. The whole instal took about 1.5hours but i had to run and get something else because I live in an Apartment and had to make sure everything could go back to normal when I move..
