Pipe no water: determine whether the shutoff, supply, leak, or branch is stopping flow

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Open several fixtures one at a time, including a nearby cold outlet and a hot outlet if applicable, and compare them with the affected point without removing wall or pipe coverings.

   Expected result: Record no water everywhere, no water on one floor or branch, one faucet only, hot water only, cold water only, or water that sputters briefly and then stops.

   Next step: Use the matching whole-home, local, hot-water, leak, or frozen-pipe branch; do not order a replacement pipe before the scope is established.

   Stop if: Stop for sudden loss accompanied by a leak, flooding, wet wall or ceiling, frost or bulging, water near electricity, or an unsafe access area.

   Why this matters

   Why: A whole-home pattern points upstream to the main shutoff, supply, service line, well or pressure equipment, utility interruption, or major leak. A single-outlet pattern supports a local valve, screen, faucet, or branch restriction; hot-only loss supports the water-heater branch.

2. Check 2

   When only one outlet is dry, inspect that fixture's visible stop valve, connection, and accessible aerator or inlet screen; remove a screen only if the fixture instructions permit it and it turns without force.

   Expected result: Record a closed or partly closed valve, scale or debris at the screen, a kinked visible supply tube, a leak, a normal local assembly, or a component that cannot be accessed safely.

   Next step: Restore only a plainly closed valve or clean an accessible screen according to its instructions, then make one retest. Call a plumber if the valve is stiff, leaks, or the branch needs wall or floor access.

   Stop if: Do not force corroded fittings, remove concealed valves, cut tubing, or continue with water escaping at the wall or connection.

   Why this matters

   Why: A local restriction can stop one outlet while the house supply remains normal. A normal local assembly moves the check toward the branch pipe or upstream supply; a leak can both reduce flow and cause damage.

3. Check 3

   Locate the visible main shutoff near the meter or the point where the water pipe enters the home, and observe whether it is fully open and dry without forcing the handle.

   Expected result: Record a normal open position, a partly closed position, a handle that turns without stopping, a seized handle, or dripping from the valve stem or body.

   Next step: If the valve is plainly open and dry, continue with utility, leak, and pressure checks. If it is damaged, stuck, or leaking, leave it stable and call a licensed plumber or water utility.

   Stop if: Do not force a gate or ball valve, remove the meter, dismantle the valve, or keep operating a stem that begins to leak heavily.

   Why this matters

   Why: A partly closed main valve can stop or severely restrict water to the home. A spinning, seized, or dripping valve may be defective and can turn an inspection into a leak; it does not justify force or disassembly.

4. Check 4

   Check the water utility's outage information or ask whether nearby properties are also without water, then observe the meter and visible service line when every intended water use is stopped.

   Expected result: Record a confirmed area outage, a still meter and dry service line, meter movement with no fixture open, running-water sounds, a wet or soft ground area, or no safe way to inspect the service line.

   Next step: Contact the utility for an outage or meter-side concern. For an in-home leak, keep water use off and arrange a plumber; do not excavate or open walls to locate the pipe yourself.

   Stop if: Stop for flooding, a burst line, electrical contact, a service-line leak, unstable ground, or any need to access a buried or pressurized connection.

   Why this matters

   Why: A neighborhood outage or utility-side issue is not repaired by opening household piping. Meter movement, running sounds, or wet ground supports an in-home or service-line leak; a still meter with no area outage keeps a shutoff, branch restriction, or concealed failure in play.

5. Check 5

   If a hose bibb is safe, dry, and accessible, turn off all water-using fixtures and systems, attach a suitable pressure gauge as EPA describes, open the bibb fully, and record the static reading without changing a pressure regulator.

   Expected result: Record pressure in or near EPA WaterSense's 45–60 psi range, much lower than 45 psi, much higher than 60 psi, a reading that changes unexpectedly, or a connection that leaks or will not seal.

   Next step: Record the reading and outlet pattern for a plumber or utility. Arrange professional assessment when the reading is outside the range, unstable, or inconsistent with the fixtures.

   Stop if: Do not use a leaking or damaged bibb, adjust a PRV by guesswork, connect to an unknown fitting, or continue if the gauge sprays or the pressure behaves erratically.

   Why this matters

   Why: A low static reading supports a supply, leak, shutoff, well, or regulator issue; a high reading supports professional regulator and code review; a normal static reading with no water at one outlet points back toward a local or branch restriction. A gauge cannot identify a concealed pipe fault by itself.

6. Check 6

   If the outage began during freezing weather, inspect only safely visible pipes in a basement, crawlspace, garage, cabinet, or exterior-wall area for frost, bulging, split seams, wet insulation, or a developing leak; do not remove wall material or apply direct heat.

   Expected result: Record a dry intact pipe, frost or a solid-feeling section, bulging or cracked pipe, wet insulation or dripping water, or no safe visibility.

   Next step: For suspected freezing or damage, shut off the water before thawing or repair and arrange qualified plumbing service. If there is no damage and only an exposed line is cold, follow the property and pipe manufacturer's safe winter guidance rather than improvising heat.

   Stop if: Never use an open flame, torch, kerosene heater, or improvised electrical heater to thaw a pipe; stop for a burst, active leak, wet wall, or concealed access requirement.

   Why this matters

   Why: Frost can indicate a frozen line and a bulge or split can release water as it thaws. A dry visible pipe does not clear a concealed freeze or service-line problem; direct heat can damage the pipe or ignite nearby material.
