The tools required to install a Moen faucet vary depending on the specific model. Some of the tools that Moen recommends for installing its Single Handle Kitchen Faucet include an adjustable wrench, a basin wrench, standard pliers and channel lock pliers.
The company also recommends that safety glasses be worn while removing the old faucet and installing the new one. A flashlight may also come in handy when connecting the supply lines underneath the sink. The basin wrench or channel lock pliers are typically used to remove the old faucet's mounting hardware. When disconnecting the flex supply lines from the stop valve under the sink, two sets of pliers are needed. If the old mounting hardware is corroded or difficult to remove, Moen recommends using a penetrating oil spray to help loosen the hardware and make it easier to remove.
Depending on the model, it may take anywhere between one to three hours to complete the faucet installation. When installing a new faucet, the water supply should be turned off and the faucet turned on to ensure the water is completely off and the lines are drained. It is also important to thoroughly clean and dry the mounting surface on the sink after removing the old faucet.
