A dripping faucet almost always needs a new cartridge, washer or seat; weak or uneven flow is usually a clogged aerator; and water under the sink usually comes from a supply line or a loose connection. Most faucets can be repaired rather than replaced. Call the number on this page to be connected with a local plumber in Denver.

What kind of faucet do you have?
The repair depends on what is inside the body. A single handle that swings and lifts usually holds a cartridge or a ceramic disc. Older two-handle faucets that tighten with a twist often use compression washers that wear flat. Knowing the brand helps, since replacement parts are model specific. A plumber will often bring the old part to match it exactly.
Common problems and their fixes
- Steady drip from the spout: worn cartridge, washer or valve seat.
- Water seeping around the handle: failed O-rings or packing.
- Spray going sideways or flow weakened: mineral deposits or debris in the aerator.
- Pullout sprayer leaking or retracting poorly: worn hose or a missing weight.
- Puddle in the cabinet: supply line, shutoff valve or drain connection.
Denver water and your aerator
Denver Water describes its supply as soft to moderately hard, harder in the southern part of the system and slightly harder in winter. Over time, minerals can collect on aerator screens and inside cartridges, which is why unscrewing and cleaning the aerator is a good first step when flow drops. If several fixtures lose pressure at once, the problem is more likely in the supply piping than the faucet.
Why a small drip deserves attention
Denver Water lists toilets and faucets as the places to check first for household leaks. A drip wastes water every hour it runs and can stain or etch the sink. Leaks under the sink are more serious because they can rot the cabinet floor unseen. Shutoff valves under older sinks are often stiff or seized; if one won't turn fully, a plumber can replace it during the same visit so you have working shutoffs for next time.
Repair or replace
Replacing a cartridge or washer is usually the simplest fix. A new faucet makes more sense when the body is corroded or cracked, parts are discontinued, or you want a different style. Sink and fixture work in single-family and duplex homes falls under Denver's quick permits, applied for online.
What affects the price
Cost depends on the faucet type and brand, whether parts are on hand, the condition of the shutoffs and supply lines, and whether the faucet is repaired or replaced. Get the diagnosis and quote before work starts.
