The first factor to note when installing a kitchen faucet is that there exists a variety of types all of which can have different installation instructions. The steps are as follows: place gasket over the faucet holes and set the watertight plate, feed the lines of faucet through the hole, install washers and nuts and connect the water supply lines (making sure they are tight), remove the aerator and let the water run to clear the faucet lines, then finally turn the faucet off and position the aerator back.

To fix a leaking kitchen faucet, it must be disassembled with parts examined for damages. First turn off the water by use of the shut-off valves to allow for maintenance. Second, switch the faucet handle to the running or “on” position to release any remaining water or pressure. Then close the drain and remove the aerator for close inspection. Parts may possibly be in need of replacement.

There is not a set standard faucet size used for a kitchen sink although this is important to check. The two factors to consider are functionality and proportion. A higher spout is recommended as it provides more space to stack pots for washing. However, a spout with considerable height may not fit depending on the physical restraints of the space. The reach distance or horizontal dimension from the spout to the connection of the faucet to the sink also needs to be considered to make for the best position of the water stream (typically targeting the drain).
