Check the elements contained in the faucet bag: 1 faucet, 1 nut, 2 gaskets (2 flat or 1 flat and 1 beveled).
See if the leak is coming from the spout (where the water is supposed to come out) or from where the faucet meets the stainless steel bowl. - If the leak is from the spout, tighten the round base under the lever clockwise. - If the leak is at the sealing area, make sure the washers are properly installed. If this is the case, tighten the valve nut with a wrench (mm by mm). Before tightening, make sure that all surfaces are completely dry so that the seals do not slip when tightening.
- If none of these solutions work, contact customer service.
