Kitchen Faucet 3-in-1 Water Filtration: Leaking Under The Sink Base

24/7 Leak: If the 3-in-1 Water Filtration Pulldown Kitchen Faucet is leaking under the sink 24 hours a day, use Figure 1 below to check the home shut off valves/angle stops (#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 (1-800-289-6636).

Intermittent Leak: If the 3-in-1 Water Filtration Pulldown Kitchen Faucet is only leaking under the sink after the faucet has been used, the issue would be from another of the under deck hoses/lines (Figure 2 and 3) .  This faucet is paired with a Moen filtration system (F9800 Advanced Filtration or F9900 Reverse Osmosis) see Figure 3 for a detailed diagram of the under deck configuration. If the leak is from one of these hoses/lines contact us by calling 1-800-BUY-MOEN (1-800-289-6636).
