Faucet Keeps Dripping Troubleshooting Guides

A faucet that drips from the spout after the handle is fully off usually has a shutoff problem in the cartridge or its seals, but first confirm the water is not coming from the handle, spout base, hose connection, or supply fitting. Close the accessible hot and cold stop valves gently, identify the faucet model, and clean only an accessible aerator if flow is distorted.

If an American Standard sink faucet keeps dripping after it is turned off, first identify whether water is coming from the spout, around the handle or faucet base, or from a supply connection below the sink. A spout drip with dry external connections points toward the faucet's shutoff valve or cartridge; a drip under the sink points toward a fitting, hose, O-ring, or body connection instead.

An American Standard sink faucet that keeps dripping is not automatically an O-ring problem. First dry the faucet and identify whether water comes from the spout outlet with the handles off, from the rotating spout base or handle area, or from a supply connection below the sink.

First find where the American Standard sink faucet is dripping: from the spout with the handles off, around a handle or valve stem, or below the sink at a supply connection. Turn off the hot and cold stop valves before opening a handle or valve area, dry the faucet, and observe whether the drip stops.

A Delta sink faucet that keeps dripping with the handle off may have a worn or contaminated cartridge, but the drip location and faucet design matter before choosing a part. First distinguish a short-lived drop of retained water from a continuous drip, then classify whether water comes from the spout, around the handle or base, or underneath the sink.

For a Delta sink faucet that keeps dripping, first identify whether water is coming from the spout or aerator when the faucet is off, around a handle or base, or from a connection underneath the sink. A spout drip can come from sediment or worn seats and springs on some two-handle designs, or a model-specific cartridge or valve on a single-handle or DST design.

A Kohler sink faucet that keeps dripping after the handle is off usually has either a temporary spout drip from water or debris at the aerator, or a continuous leak because the valve or cartridge is no longer sealing. First identify exactly where the water appears: the end of the spout, under the handle, around the spout base, at a side sprayer or hose, or below the sink.

If a Moen sink faucet keeps dripping after it is turned off, first determine whether water comes from the spout, around the handle or base, or from a connection below the sink, and whether it drips only after use or continuously. Moen says a spout that will not shut off is usually related to the cartridge, but its cartridges are not interchangeable; the model and handle style must be confirmed.

A faucet that drips from the spout while its handle is fully off often has an internal cartridge, seat, or seal that is not closing, but a leak around the handle, faucet base, supply connection, or under the sink points to a different repair. First locate the water, identify whether the faucet has one or two handles, and record the faucet model if it is visible.

A sink faucet that drips briefly after the handle is closed may only be releasing water held in the spout or have debris at the aerator. A drip that continues steadily for hours or all day usually points to a worn valve or cartridge under the handle; worn washers, O-rings, or a handle mechanism can cause similar symptoms depending on the faucet design.

First separate a drip from the end of the spout from water escaping where the spout meets the faucet body or the faucet meets the sink. A drip that continues after the handles are off usually points to the faucet's valve or cartridge not fully closing; a base leak that appears only while water is running is more consistent with spout seals or O-rings, while a base leak that continues after shutoff can involve the valve, cartridge, check valve, or another internal seal.

If the sink's hot and cold shutoff valves work but the faucet still drips with its handle off, the shutoffs are not the same as the faucet's internal flow-control valve. A brief drip from the spout may be residual water or aerator debris; a drip that continues steadily usually points to a worn cartridge, valve, washer, O-ring, or handle mechanism.

First separate a short-lived drip after shutoff from a faucet that continues dripping. From a dry, stable position, record whether water comes from the spout, handle, faucet base, or under the counter; whether it stops after a short settling period or continues while the handle is off; and whether the drip is accompanied by a spreading leak, cabinet moisture, or a failed fixture shutoff.

A sink faucet that keeps dripping may have a worn or displaced O-ring, but the drip location decides whether the cartridge is also in scope. A drip from the spout tip while the handle is off points toward the cartridge or valve seal; water between a rotating spout and its body, or around the spout base, makes a spout O-ring more relevant.
