Water flooding a residential kitchen

Watch for these signs

What counts as a plumbing emergency

  • A pipe or supply line has burst and water is escaping
  • Water is coming through a ceiling, wall, or floor
  • Sewage is backing up into a tub, shower, floor drain, or toilet
  • A water heater is leaking or its relief valve is spraying
  • The whole property has lost water, or the meter spins with everything off
  • A commercial restroom or kitchen cannot operate
  • You smell gas (leave and call 911 or your gas utility first)

Your options

Call now, or schedule a visit?

Emergency service is there 24/7 for problems that cannot wait. Some problems can, once they are made safe.

01

Call now

Water you cannot stop, sewage inside, a leaking water heater, no water to the property, or a business that cannot open its restrooms or kitchen. Shut off what you safely can, then call.

02

Make it safe, then decide

A leak that stops when you close the fixture valve, or one backed-up drain while the others work, can be contained. Close the valve, stop using that fixture, and tell us what you see so we can decide together whether it needs emergency service.

03

Schedule a regular visit

A dripping faucet, a toilet that runs now and then, or a drain that is slow but still flows is not an emergency. Book it as a normal repair.

Around the Valley

Know where your main water shutoff is before you need it

Arizona heat, hard-water deposits, and infrequently used valves can make old shutoffs difficult to operate. Test and label accessible valves during normal maintenance, not during a flood.

Planning the work

What affects the price

  • Time, urgency, and safe access
  • Ability to isolate the failed area
  • Pipe, fixture, valve, sewer, or water-heater failure
  • Extent of plumbing repair after stabilization
  • Separate mitigation and finish restoration needs

How to shut off the water in a plumbing emergency

Stopping the water is the single biggest thing you can do before a plumber arrives. Start at the closest valve and work back toward the main.

  • Fixture valves: under each sink, behind each toilet, and behind the washer. Turn the handle clockwise until it stops.
  • Water heater: close the cold-water valve on the pipe above the heater, and turn off its gas or power if the house water will stay off.
  • Main shutoff: look where the water line enters the building, near a front hose bib, in the garage, or in a ground box. A round handle turns clockwise; a lever turns a quarter turn until it sits across the pipe.
  • Relieve the pressure: once the main is closed, open a faucet at the lowest point of the building to drain what is left in the lines.
  • Cannot find or close the main: call your water utility's emergency line and ask whether they can shut the water off at the meter.

What to tell us when you call

A clear picture on the first call helps us send the right technician with the right parts. Have these ready if you can:

  • The address, gate or building access, and the best phone number for the person on site
  • What is leaking or backing up, where, and whether you have shut the water off
  • Whether sewage, electrical equipment, or a gas smell is involved
  • The property type, and for a business, which restrooms, kitchens, tenants, or operations are affected
  • Photos or a short video, if it is safe to take them

After-hours emergencies at businesses and managed properties

Restaurants, retail, offices, apartments, and HOAs can call for emergency plumbing 24/7, including nights, weekends, and holidays. A flooded restroom, a sewer backup in a dining room, or a lift station alarm rarely waits for business hours.

For managed properties, give us the site contact, any spending limit that needs approval, keys, lockbox or alarm instructions, and which units or tenants are affected. Lift station alarms and failed pumps are covered on our lift station page.

Common questions

24/7 emergency plumbing questions

Do you offer 24/7 emergency plumbing?

Yes. Emergency plumbing service is available 24 hours a day, 7 days a week, including nights, weekends, and holidays, in Mesa, Phoenix, and across the Valley, and same-day emergency service is available. Call 480-663-2255. Repairs that are not emergencies are scheduled as regular visits, and same-day service is often available for those too, depending on the job.

How soon can a plumber get here?

Same-day emergency service is available. The arrival time depends on where the property is, the time of day, and the emergencies already under way, so ask when you call. Until the technician arrives, use the shutoff steps above to limit the damage.

What should I do during an active water leak?

If it is safe, close the nearest fixture shutoff or the building's main water valve. Keep people away from water near electrical equipment, then call us.

What if I smell gas?

Leave the building, avoid switches or ignition sources, and call 911 or your gas utility from a safe location. Call a plumber only after the immediate hazard has been addressed.

Do you handle after-hours emergencies for businesses and rental properties?

Yes. Emergency service is available 24/7 for businesses, restaurants, apartments, HOAs, and other managed properties. Share the site contact, access instructions, and authorization limits when you call.

What does an emergency call cost?

The price depends on the failure, the access, and the repair needed. Ask about any charges when you call; we explain the price before you approve the work.
