How to Shut Off Your Main Water Valve
To shut off your main water valve, go to where the supply pipe enters the building and turn the lever a quarter turn, or spin a wheel clockwise until it stops. Then open a faucet on the lowest and highest floors. Learning the location before a leak starts is what saves the day.

Where to find your main water valve before you need it
Follow the line from the street.
The main shutoff is the one valve that stops all the water in the house at once. When a pipe splits or a supply line lets go, the minutes spent looking for it are minutes of flooding. The best time to find it is when nothing is wrong.
Where does a Federal Way house hide its main shutoff?
It sits where the water line enters the building, so start at the side of the house nearest the street. In homes over a crawlspace, the valve is often just inside the crawlspace access or on the first stretch of pipe after it comes through the foundation. In houses with a garage, look on the wall shared with the street side, near the water heater or in a utility corner. Basements, laundry rooms and hall closets with a pipe running through are other common spots. Some homes also have a valve on an outside wall under a small cover.
Follow the pipe. The line from the street runs to a pressure regulator in some houses, a bulb-shaped brass fitting, and the valve is just before or after it. Tracing the water heater’s cold supply back toward the wall is another way to find it. Once you have it, tie a bright tag to the handle and photograph it.
| Home type | Where to look first | Tip |
|---|---|---|
| Crawlspace house | Near the access hatch, on the first pipe through the wall | Bring a flashlight and gloves |
| Garage house | Street-side wall, near the heater | Check behind shelving |
| Basement house | Where the line enters, often by the water heater | Look low on the front wall |
| Townhome or condo | Utility closet or under the kitchen sink | Ask the building which shutoff is yours |
| Older house | Outside wall cap or near the meter side | May be stiff from disuse |
Is the meter box valve the same thing?
No. The meter sits in a lidded box near the street or the property line, and the valve there belongs to your water provider. It can be used in an emergency if the house has no working shutoff, but the provider generally expects customers to use the valve at the house, and the fittings in the box are easy to damage. Your water bill names the provider, and most of Federal Way is served by Lakehaven, who can tell you what their policy is for the valve at your meter.
Ball valve or gate valve: what you are turning
The handle tells you which.
Not all valves work the same way, and using the wrong motion can break a stiff one. A quick look at the handle tells you which kind you have.
What kind of valve do you have?
Two types are common. A ball valve has a straight lever handle. Turn it a quarter turn so the lever lies across the pipe and the water is off. A gate valve wears a round wheel instead, and closing it takes several full clockwise rotations. Gate valves are the older style, and they tend to seize or weep at the stem after years untouched, so turn one smoothly and stop if it fights back.
If the valve will not budge, skip the wrench and the pipe-on-the-handle trick. A cracked valve body floods the house faster than the leak you started with. Move to the meter-side option or call a plumber. A stiff valve is also worth replacing before an emergency, and the plumbing repair page explains that service.
| Valve | Looks like | To shut off | Watch for |
|---|---|---|---|
| Ball valve | Straight lever handle | Quarter turn, lever across the pipe | Handle that spins loosely |
| Gate valve | Round wheel | Clockwise, several turns | Stiffness, drip at the stem |
| Globe or stop valve | Round knob, bulbous body | Clockwise until snug | Packing leaks |
| Lever with a locking tab | Lever plus a small hole | Quarter turn, then lock if needed | Do not force the tab |
What if there is a pressure regulator?
A few houses have a brass bell-shaped fitting beside the main valve. That is a pressure regulator, and it protects fixtures from high street pressure. Leave it alone. The shutoff is the separate valve beside it. If the regulator drips or hums, that is a job for a plumber, and the guide on why is my water pressure low explains how pressure problems show up.
- Bell-shaped brass fittingPressure regulator; do not turn it
- Valve beside itThe shutoff you want

- Test gauge portSmall nipple; leave it alone
How to shut off your main water valve, step by step
Ten seconds once you know.
Practice makes this a ten-second job. Do it once on a calm afternoon and again when the family needs to know.
How to shut off your main water valve, step by step
Let everyone know the water is about to stop. Close the valve in one smooth motion: a quarter turn for a ball valve, clockwise to the stop for a gate valve. No hard cranking at the end. Open a faucet on the lowest level, such as a tub or outdoor bib, and one on the highest. The pipes drain, and the flow dwindling to nothing proves the shutoff worked.
Then protect the heater. With the main off, a tank heater can draw air or overheat if it empties. Switch off the electric heater at the breaker or set a gas heater to pilot. Flush toilets once to empty the tanks, but do not refill them. Take photos of any damage and call. If a pipe has split, what to do when a pipe bursts takes you through the next steps.
Warn the household
Everyone should know the water is going off.
Close the valve
Quarter turn for a lever; clockwise for a wheel.
Open low and high taps
Drains the pipes and confirms the shutoff.
Switch off the heater
Breaker off, or gas to pilot.
Look and document
Photos of the leak and damage.
If the valve will not turn or leaks
The meter box valve is an option only if it is safe to reach, and it usually takes a special key. With water still flooding in, step away, flip the breaker only from a dry spot, and ring for emergency help.
Restoring water after you shut it off
Slow and watchful.
Closing the valve is half of the job. Turning the water back on correctly prevents a second leak.
How do you turn the water back on?
Close every faucet except one on the highest floor, which stays open. Then ease the main valve open a little at a time, listening as you go. A rush of air and spitting from the open tap is normal as the pipes refill. When the tap runs steady, close it and walk the house looking for drips at joints, under sinks, behind toilets and at the heater.
Turn the heater back on only after hot taps run bubble-free, which tells you the tank has filled. Faucet aerators may clog with grit after the pipes have been disturbed. Unscrew and rinse them if flow seems weak. If the pressure feels low afterward, low water pressure covers the causes.
| Step | What to watch | Problem sign |
|---|---|---|
| Open the valve slowly | Hissing and air at the tap | Banging in the pipes |
| Run the high tap | Steady stream | Sputtering that does not clear |
| Walk the house | Dry joints and traps | Any drip or stain |
| Refill the heater | Hot taps bubble-free | Tank not filling |
| Check the meter | Dial still when taps are off | Dial moving = leak |
What about water hammer?
Opening a valve fast can slam the pipes with a bang called water hammer. It stresses fittings and loosens joints over time. Opening slowly and keeping one tap open avoids it. If banging is common in your house even at normal use, a plumber can check the straps, the pressure and the need for arrestors. The fix is usually small, and it protects the plumbing.
- Open the main slowlyKeeps the surge small
- Keep a tap open at firstLets air escape
- Banging at normal useStrapping, pressure or arrestors may need work
- Loose pipes in the crawlspaceOften the source of the knock
Keeping the main shutoff in working order
A seized valve is no valve.
A valve you cannot turn is a valve you do not have. Keep yours in working order.
How to keep the main valve working
Turn the main valve closed and open again once or twice a year. Gate valves in particular seize when left alone, and mineral buildup in the stem can lock them. If the handle is stiff or the stem weeps, tell a plumber. Replacing an aging gate valve with a ball valve is a quick job that turns a risk into a ten-second shutoff. Do it before the storm season or before a cold snap, not during.
Also test the individual shutoffs under sinks and behind toilets. These small stops let you isolate a single fixture without losing water to the whole house. If any are stuck, rusted or missing, they are worth replacing, and the faucet repair and toilet repair pages explain those jobs.
Exercise the main twice a year
Close and reopen it smoothly.
Watch the stem for drips
A weep means the packing is tired.
Test the fixture stops
Under sinks and behind toilets.
Replace seized valves
Better done on a calm day.
Tag and photograph
Let everyone know where it is.
Should you know about other shutoffs?
Yes. Gas has its own valve at the gas meter, which is not for casual use. For a gas smell, leave first and read signs of a gas leak in your home from outside. The water heater has a cold inlet valve. Outdoor irrigation often has its own valve or a backflow assembly, and the backflow testing page explains why that matters. Your electrical panel is the final shutoff you should know when water and wiring meet.
| Shutoff | Where | Stops |
|---|---|---|
| Main water | Where the line enters the house | All water inside |
| Heater cold inlet | Pipe at the top of the tank | Water to the heater only |
| Fixture stops | Under sinks, behind toilets | One fixture |
| Irrigation or hose bib | Garage, crawlspace or outdoors | Outside lines |
| Electric panel | Garage, hall or utility room | Power, if water meets wiring |
Rentals, condos and what to do when you cannot find it
Shared plumbing changes the plan.
Some households have extra things to sort out.
Renting, or in a townhome or condo?
Many Federal Way households rent, and the shutoff is not always inside your door. In a single-family rental, ask the landlord or property manager to show you the valve when you move in. In a townhome or condo, a shutoff may serve only your unit, or a whole stack, or an entire building. Ask the manager which valve is yours and where it is, and write the answer down. Shutting off a shared stack affects neighbors, so tell the building before you do it unless water is actively flooding.
If you do not know where the valve is in an emergency, ring for help while you look. A plumber on the phone can often talk you to the valve. The emergency plumber page explains how the call works at any hour.
| Where you live | Whose shutoff | What to do |
|---|---|---|
| Single-family rental | Landlord’s, inside the home | Ask to be shown it on day one |
| Townhome | May be per unit or shared | Ask the HOA or manager |
| Condo | Unit, stack or building | Get the location in writing |
| Apartment | Often a closet or building riser | Call management first, unless flooding |
When should you call a plumber about the main valve?
Call when the valve will not turn, when it drips or when it has not moved in years. Call if the shutoff works but the leak continues past it, which can mean a second break or a stuck valve that is only partly closed. Also call to add a shutoff where none exists. For after-hours flooding, the burst pipe repair page and the 24-hour plumber page apply.
Reasons to call a plumber about the valve
Ring if you see any of these.
Valve will not turn
A stuck valve is better replaced on a calm day.
Drip at the stem
The packing is wearing out.
Water continues after shutoff
A second break or a partly closed valve.
No main shutoff at all
A plumber can add one.
