Installation was pretty easy by just looking at the directions and at how my old one was connected. Took about 20 minutes from start to finish to remove the old one and install the new one. The drain was another issue! It took several tries as it kept leaking so I took off most of the rubber washers it came with and used plumbers putty instead. It definitely sits up too high on the inside of the sink to let the water drain if you use all of the intended plastic and foam pieces. After taking them off and using plumbers putty it made a nice seal that is low enough to let the water drain. Other than that, I’m very happy with this purchase and would buy it again. If the water runs out too far from the faucet into the sink just turn the water off at the pipes at about the halfway mark in the water should hit the drain￼ top perfectly. It pushes out a lot of water.
