The most common plumbing emergencies are burst or leaking pipes, sewer backups, clogged toilets, and water heater failures. Some demand immediate action. Others can wait a day or two without becoming disasters. Knowing the difference, and knowing what to do in the first five minutes, limits the damage and gives your plumber something manageable to work with when they arrive.
In Tucson and across Southern Arizona, a few local factors shape how plumbing emergencies play out. Most homes sit on concrete slabs with no basement to catch water before it spreads. Garage water heaters without floor drains are common. A handful of freezing nights each winter can split an exposed hose bib or backflow preventer before sunrise. And many neighborhoods have sewer lines and plumbing that are now decades old. Water where it should not be means shut off the supply and call Rite Way. Our 24/7 emergency plumbers serve Tucson and Southern Arizona around the clock.
Key Takeaways
- Shut off the water first. Know where your main shutoff, fixture shutoffs, and water heater supply valve are before an emergency happens.
- Not every plumbing problem is an emergency. Burst pipes, sewage backups, and active leaks are. A dripping faucet and a running toilet can wait.
- In Tucson, most homes are on slab foundations. Leaks spread under flooring rather than dripping to a visible location below.
- A gas smell near a water heater is not a plumbing emergency. Leave the home immediately and call 911 and Southwest Gas from outside.

First, Know Where to Shut Off Your Water
Before an emergency happens is the right time to locate your shutoffs. In Tucson, the main water shutoff is typically near the foundation or in a utility area indoors. Individual fixtures have shutoffs under sinks and behind toilets. The water heater has a cold water supply valve at the top of the unit. Knowing these three locations can stop significant damage in the first two minutes of an emergency.
10 Most Common Plumbing Emergencies
1. Leaking Faucets and Taps
Not usually an emergency, but do not ignore it. A dripping faucet wastes water continuously and can signal a worn valve or pressure issue.
Do this now: Close the fixture shutoff under the sink if the drip is significant. Schedule a repair when convenient.
Faucet repair and replacement is a routine Rite Way service.
2. Clogged Toilets
A clogged toilet becomes an emergency when it is overflowing or is the only toilet in the home. In Tucson, older homes with original drain lines are more prone to clogs that go deeper than the toilet trap.
Do this now: Stop flushing immediately. Close the shutoff valve behind the toilet. Attempt to clear with a plunger using slow, steady pressure. If multiple drains are backing up, the blockage may be in the main line.
Toilet repair and drain cleaning are both available through Rite Way.
3. Water Heater Failures
A water heater leaking from the tank body, making loud sounds, or producing no hot water warrants prompt attention. In Tucson, hard water accelerates sediment buildup and tank wear, and many homes have water heaters in garages with no floor drain and a slow leak can spread across the slab before anyone notices. Rite Way puts the typical tank lifespan at 8 to 12 years.
Do this now: Close the cold supply valve at the top of the unit. For gas units, set the gas valve to off or pilot. If you smell gas, leave immediately and call 911 and Southwest Gas from outside.
Rite Way handles water heater repair and replacement. Our post on water heater leaking covers what to check first.
4. Leaking Pipes
Pipe leaks range from a slow drip at a fitting to an active stream. In Tucson, a leak in a pipe beneath the slab can spread under the floor undetected. Soft spots in flooring, unexplained bill increases, or warm patches on tile are worth investigating.
Do this now: If you cannot isolate the leak to one fixture, close the main shutoff. Catch water, move valuables, and check whether the floor feels warm or damp in an unexpected location.
Rite Way’s leak detection uses non-invasive equipment to find leaks under concrete. Our post on signs of a slab leak covers what to watch for.
5. Burst Pipes
A burst pipe releases water rapidly. In Tucson, the most likely trigger is one of the handful of freezing nights each winter hitting exposed outdoor hose bibs, backflow preventers, or pipes in unheated garages. Age and high water pressure contribute to failures in older homes year-round.
Do this now: Close the main shutoff immediately. Turn off power at the breaker to any area where water is near electrical panels or appliances. Call for emergency service.
Rite Way’s 24/7 emergency plumbers are available around the clock.
6. Clogged Garbage Disposal
A disposal that is jammed, humming but not spinning, or backing up with standing water should be shut off immediately.
Do this now: Turn off the disposal at the wall switch. Never put your hand inside. Use the reset button on the bottom and the hex socket to free the grinding plate manually. If water still will not drain, the clog may be in the line below.
Rite Way handles garbage disposal repair and installation.
7. Sewage Backups
Sewage backing up into drains, tubs, or toilets is a serious emergency and a genuine health hazard. Common causes in Tucson include tree root intrusion, grease buildup, and deteriorating pipe materials in homes from the 1970s and earlier. Homes on septic in outlying areas such as Vail and Marana may experience backups when the tank needs pumping or the leach field is failing.
Do this now: Stop using all water immediately. Keep children and pets away. Do not attempt to plunge or clear the drain. Call for emergency service.
Rite Way handles sewer line repair and sewer camera inspection. For septic-served homes, reach our septic services team.
8. High Water Pressure
High water pressure stresses pipe joints, fittings, and appliances throughout the home. Tucson Water recommends a pressure-regulating valve when home pressure exceeds 80 psi, and Pima County has required PRVs on new construction since 2005. Signs include banging pipes, a dripping T&P valve, or fixtures that wear out faster than expected.
Do this now: Note whether you hear hammering in the pipes or if the water heater’s T&P valve drips. Schedule a pressure test.
Rite Way’s plumbing repair team can check pressure and recommend the fix.
9. Running Toilets
Not a plumbing emergency, but worth addressing. A running toilet wastes significant water and usually points to a worn flapper, faulty fill valve, or float that needs adjustment.
Do this now: Check whether the flapper is seated properly. Jiggling the handle sometimes reseats it. If it will not stop, close the shutoff valve behind the toilet until the repair is made.
Toilet repair is a straightforward Rite Way service.
10. Leaking or Failing Washing Machine Hoses
Rubber washing machine hoses degrade over time and can fail without warning. In Tucson, where laundry rooms often sit on slab floors with no floor drain, a failed hose spreads water across the slab and under adjacent flooring before it is noticed. Bulging, cracking, or corrosion at the fittings are signs a hose is near the end of its life.
Do this now: Close the hot and cold supply valves behind the washer. Move the machine to assess the hose condition. Replace rubber hoses every five to seven years or switch to braided stainless steel.
Rite Way’s plumbing repair team can assess connections and recommend the right replacement.
Plumbing Emergencies to Watch for in Tucson Homes
Slab leaks: Most Tucson homes have no basement. Leaks beneath the slab spread under flooring silently. Warm spots on tile, musty odors, or a climbing water bill without explanation are early signals worth investigating.
Freezing nights: Tucson sees a handful of freezing nights between December and February. Exposed hose bibs, backflow preventers, and pipes in unheated garages carry the most risk. Disconnect hoses and cover outdoor fixtures before temperatures drop.
Older sewer lines: Tucson’s median home was built in 1979. Many neighborhoods have original sewer lines where root intrusion and deteriorating materials are genuine concerns. A proactive camera inspection finds problems before they become emergencies.
Septic systems: Homes in outlying parts of Southern Arizona are often on septic. A backup in a septic-served home requires a different response than a city sewer backup. Rite Way’s septic services cover pumping, inspection, and repair.
