Kitchen Faucet: Leaking Under The Sink Base

If the kitchen faucet is leaking under the sink 24 hours a day, use Figure 1 below to check the home shut off valves (angle stop) (#1), the house supply lines (#2) that lead to the faucet and the Moen faucet supply lines (#3). When the leak is coming from from the house supply lines or the home shut off valves (#1 or 2), you will need to purchase those from your local home store. If the faucet is leaking from the Moen faucet supply lines (#3), contact us by calling 1-800-BUY-MOEN. If the kitchen faucet is only leaking under the sink after the faucet has been used, see Figure 2 pointing to the cluster of faucet hose connections located below the sink. The faucet will need to be identified for the correct part numbers, contact us by calling 1-800-BUY-MOEN.
