Why faucets drip and leak
Most faucets have a moving part inside that wears with use. A cartridge, a ball, or a rubber seat and washer sits behind the handle and controls the flow. When it wears, the faucet drips from the spout or leaks from the handle.
| Faucet type | What wears out | Typical repair |
|---|---|---|
| Single handle cartridge | The cartridge and its O-rings | Replace the cartridge |
| Two handle compression | Rubber washers and seats | Replace washers and seats |
| Ball style | Springs, seats, and the ball | Replace the repair kit |
| Ceramic disc | Disc cylinder or seals | Replace the cylinder |
A drip of one drop per second can waste thousands of gallons over a year, which shows up on a quarterly water bill. If the water bill has climbed and a fixture is dripping, the two may be linked, and leak detection can rule out anything bigger.
Valve will not shut off: what to do first
The small shutoff valves under a sink are used rarely and often seize. A valve that drips from its stem, will not close, or has crusted over needs to be replaced. Without a working shutoff, every faucet repair has to start at the main water valve.
Supply lines are the braided or plastic hoses that connect the valve to the faucet. They age, kink, and burst. A burst supply line can empty gallons a minute, and replacing them every several years is cheap insurance against a flood.
Water spraying under the sink?
Shut off the main water valve and call. A supply line failure is a quick fix once the water is stopped.
Kitchen and bathroom sinks: leaks that are not the faucet
- A wet cabinet floor may be the drain trap, not the faucet. A loose slip nut or worn washer is a quick fix.
- A slow drain with a gurgle may be a vent or branch drain problem. See drain cleaning.
- Low flow from a single faucet is often a clogged aerator or a worn cartridge.
- Low flow on every fixture can point at a pressure regulator or a leak in the service line.
Repair or replace the faucet?
Repair when
- The faucet is a quality fixture with a replaceable cartridge
- The finish is in good shape
- Parts are still available
Replace when
- The faucet is corroded or the finish is peeling
- Parts are discontinued
- You want a touchless, pull-down, or different style
Replacing a faucet is a short visit. If you are planning a larger update such as a new kitchen sink or bath, the work falls under plumbing installation.
Hard water and faucets in the Forest Lake area
The City of Forest Lake softens water at its treatment plants to an average of 5.5 to 6.5 grains per gallon, so scale buildup in city-served homes is lighter than in areas with raw hard water. Aerators still collect sediment, and white crust on a spout is a sign to clean it. Homes on private wells in nearby towns may see more mineral crust and should have the water tested.
What decides the price of faucet and sink repair
Most faucet jobs are small, and a few are not.
Insurance may cover sudden water damage from a burst supply line but not wear on the faucet.

- Close the fixture stop valves under the sink before taking anything apart.
- Dry the area and keep the cabinet floor clear so you can spot a slow drip.
- Do not use a faucet that leaks near an outlet or a light fixture.
- If a supply line is spraying, shut the main valve and call.
Who operates the street valve
According to the City of Forest Lake Water Department, the curb stop at the street is operated by city staff only. Do not count on it to stop water in an emergency, and close the main valve inside your home instead.
Common Questions
Yes. The line is open 24 hours, every day. If the water will not stop, shut off the main water valve and call.
A worn cartridge, washer, or seat is the usual cause. The plumber identifies the type and replaces the worn part.
If it is a quality fixture with available parts, yes. If the finish is failing and parts are scarce, replacement is often better.
Many plumbers advise replacing braided lines every several years, and sooner if they look frayed or bulged.
A clogged aerator or worn cartridge is the usual cause. If every fixture is low, check the main shutoff and pressure regulator.
