Understanding your home's irrigation plumbing layout (So you don't lose indoor water)¶

When an outdoor sprinkler pipe bursts, panicked homeowners often shut off the main water valve inside their house, only to discover two things: first, their indoor toilets and showers are now completely dry, and second, the outdoor yard geyser is STILL spraying full blast.

Why does shutting off the indoor house valve often fail to stop a yard sprinkler leak? Because in warm and temperate climates (such as the Southern and Western United States, Australia, and Mediterranean Europe), the underground irrigation line is tee'd off the main water line out in the front yard right next to the street water meter, before the pipe ever enters your house. Conversely, in cold northern climates with deep winter frost lines (such as Canada, the Northern and Midwest United States, and the United Kingdom), the irrigation pipe usually branches off inside the heated basement or utility room right after the indoor water meter.

Use this regional comparison table to locate your exact irrigation shutoff valves in under 60 seconds:

Step-by-step: How to shut off every type of irrigation and backflow leak¶

Scenario 1: Water is gushing from the brass bell on the side of your house (Freeze-Cracked Backflow Preventer)¶

Na veiqaravi kece ni sprinkler ni co madu ni gauna oqo e gadrevi vakalawa me tiko kina e dua na Backflow Preventer: e dua na soqoni ni valve parasa bibi ka tarova na wai ni co madu stagnant, na veivakabulabulataki, na veivakamatei ni co ca, kei na benu ni koli mai na kena sucu lesu tale ki na paipo ni wai ni gunu ni nomu matavuvale kevaka e pressuredrop na gaunisala ni koro. Na tolu na mataqali vakaitikotiko raraba sai koya na Vakasaurarataki ni vakacaca ni vakasaqa (PVB) (e tiko e dua na dome parasa wavoki se bele ena dela ni), na Vakalailaitaki na veivakasaurarataki ni vanua (RPZ) soqoni (e rua na inline jeke valves kei na dua na toba ni veivuke sobu ena lomadonu), kei na **ve vakarua ni jeke V (ni DCal) kato vakababa ena lomanibai).

Ni yaco e dua na vulaikatakata sega ni namaki se vulaitubutubu batabata ni bera ni vakayagataki na ivakarau ni sprinkler, na aisi e vakarabailevutaki ena loma ni yago parasa ena sivia na 200,000 na kilopascals (30,000 psi) ni kaukauwa, se vukataka laivi na boniti palasitika e loma ena ruku ni beleti kaukamea e cake se vakacacana na yasa ni parasa-parasa. Ena gauna ga e vakamamacataka kina na matanisiga ena mataka na palasitika ni aisi, e dua na ivurevure ni wai e drodro mai na iuniti parasa.

1. Raica na rua na iqaqalo ni lever kaukamea ena parasa ni veivakabulabulataki:
2. Na veivakabulabulataki kece ni PVB kei na RPZ lesu tale e tiko kina rua na veimama-saumaki na polo ni valves tara vakadodonu ki loma: Valve #1 (na Inlet vakasuka) ena paipo ni vakacuru ilavo vakadodonu e lako cake mai na qele se bai, kei na Valve #2 (na Outlet vakasuka) a lesu tale ki na paipo o koya.
3. Raica na vanua e vakadrodroi tiko kina na wai mai na veiwekani ki na Valve #1 (na iqaqalo ni curucuru e ra):
4. If water is shooting out from under the top metal bell cap, from the middle relief port, or from a crack ABOVE the lower lever handle: Grab the lower metal lever handle (Inlet Valve #1) and turn it 90 degrees clockwise so the handle stands perpendicular (forming a cross "+") to the pipe. The geyser will stop in two seconds, and your indoor house water remains completely unaffected.
5. Kevaka e sa ramusu na yago parasa se paipo kopa ENA RUA ni liga ni lever e ra: Na kena vukici na liga ena backflow preventer ena sega ni tarova na wai e vakadrodroi mai na rukuna.

iTukutuku 2: Sogota na Valve ni veivakaduiduitaki ni veivakasuasuataki vakatabui (Valve ni Tarova-ka-Vakayagataki ena ruku ni qele se ena ruku ni qele)¶

If the pipe has ruptured between the water main and the backflow preventer, you must close the upstream Irrigation Isolation Valve:

• Ena dua na vale e tiko kina e dua na rumu e ra se vanua ni vuka:
• Lako sobu ki na basement ka kunea na vanua e curu kina na nomu laini ni wai ni vale levu ena fuloa simede se na bai ni yavu.
• Follow the cold water pipe until you see a 19-millimeter or 25-millimeter (¾-inch or 1-inch) copper or PEX branch pipe teeing off and running up to the ceiling joist on the side of the house where your outdoor backflow preventer is mounted.
• Close the quarter-turn ball valve (turn handle 90 degrees crosswise) or round gate/globe valve wheel (turn clockwise until snug) on that branch pipe.
• In a house without a basement (Underground Yard Isolation Valve / Stop-and-Waste Valve):
• Walk to the brass backflow preventer in your yard and look at the ground directly at the base of the vertical risers, or walk a straight line between your brass backflow preventer and the street water meter box.
• Look for a small round green, black, or purple plastic lid (typically 15 centimeters / 6 inches in diameter) sitting flush with the grass or mulch.
• Pry the plastic lid up with a screwdriver. Look inside with a flashlight: you will see either a PVC or brass quarter-turn ball valve handle at the bottom of the tube, OR a deep square brass stem (a deep-bury Stop-and-Waste key valve) that uses a long steel T-bar key (cross-handle sprinkler key) to turn 90 degrees clockwise.

Scenario 3: How to turn off the main Street Water Meter Curb Valve (When all else fails)¶

If water is flooding your yard or driveway from a ruptured main line upstream of your backflow preventer and you cannot find a dedicated irrigation isolation valve, shut off the Main Street Water Meter Valve:

1. Locate the rectangular Water Meter Box: Walk out to the front edge of your lawn between the sidewalk and the street curb (or in the front planter bed) and look for a rectangular concrete, cast-iron, or heavy plastic cover labeled "WATER" or "WATER METER."
2. Lift the lid safely: Insert a long screwdriver or pliers into the finger hole and pry the lid open while standing back (watch for spiders, wasps, or snakes underneath the lid).
3. Identify the Customer Side vs. the Street Curb Stop Valve:
4. Inside the meter box, you will see the brass water meter in the center with a pipe entering from the street side and a pipe exiting toward your house.
5. Look on the House Side of the meter first: Many modern water meters have a Customer Hand Wheel or Quarter-Turn Ball Valve right on the house side of the meter that you can turn by hand.
6. Using the Brass Curb Stop Valve (Street Side of the meter): On the street side of the meter sits a heavy brass plug valve with a raised rectangular metal tab (wing) on top and a small round padlock hole on the side.
7. Slip the jaws of an adjustable wrench, slip-joint pliers, or a $12 hardware-store T-Bar Water Meter Key over that rectangular brass tab and turn it 90 degrees clockwise (¼ turn) until the rectangular tab sits crosswise (perpendicular) to the pipe and the two small padlock holes line up with each other.

Yard sinkholes and undermined driveways: assessing structural collapse danger¶

When a 25-millimeter (1-inch) Schedule 40 PVC irrigation main line splits open 45 centimeters (18 inches) underground, it does not always shoot a geyser into the air. Instead, if the clay soil and thick turf roots above the pipe hold together like a rubber blanket, the pressurized water tunnels horizontally underground, liquefying the soil and flushing thousands of kilograms of sand and silt out into the street gutter or down a storm drain.

Warning signs of an active underground washout or yard sinkhole¶

1. The "Waterbed Lawn" Blister (Hydrostatic Turf Dome): The grass sod rises 10 to 30 centimeters (4 to 12 inches) above normal grade into a spongy, undulating dome. Do not step on it or drive a riding lawnmower over it: underneath that 5-centimeter (2-inch) layer of entangled grass roots is a 60-to-120-centimeter (2-to-4-foot) deep pit of liquid mud slurry that can trap a child or pet instantly.
2. Muddy Silt Fans Pouring Over the Sidewalk or Curb: Clear water bubbling out of a lawn usually indicates a shallow broken sprinkler riser near the surface. Thick brown, sandy, or clay-colored mud slurry pouring across your driveway or through expansion joints in the concrete sidewalk means the water jet is actively excavating the structural soil sub-base beneath your hardscape.
3. Hollow Sounding Concrete Driveway or Front Steps: Once water washes out the compacted gravel base under a concrete driveway slab or front porch steps, a 10-centimeter (4-inch) thick unreinforced concrete slab is left hanging in mid-air like a fragile bridge. Walking or driving a 2,000-kilogram (4,400-pound) SUV over an undercut driveway slab will shear the concrete in half and drop the vehicle's wheel axle into the hole.

How to secure and probe a yard washout after turning off the water¶

• Wait 2 to 4 hours for standing hydrostatic water to drain before walking near the cavity: Once the water valve is closed, allow the trapped underground water dome to percolate down through the soil.
• Vakaruguta na vanua ka vakatovolea na veitiki ni simede ena dua na ititoko kaukamea balavu se sova: Ni bera ni o lako volekata na washout se vakavodoki e dua na motoka ena sala ni motoka, tu ena qele mamaca kaukauwa 2 na mita (6 na fiti) ki muri ka vakadikeva na turf kei na qele ena ruku ni bati ni sala ni motoka simede, handle balavu bshovel.
