Phoenix Plumbers.

Yeti Pros plumbing covers the job list a Phoenix-area home or business actually runs into: clogged drains and sewer backups, water heaters that quit, leaks you can hear but can’t find, slab leaks under the floor, hard-water damage, aging pipe, gas lines, and every fixture in between. It runs on the same rules as our HVAC and electrical work. A real person answers the phone, any diagnostic fee is disclosed when you book, the price is in writing before work starts, and the workmanship carries a two-year written warranty. Our plumbing work is licensed under AZ ROC #341454 (CR-37 Plumbing), held by our plumbing partner Redwood Plumbing Service & Repair LLC.

This page is the plain-English version of how plumbing works in the Valley: what our water does to pipes and water heaters, which cities want a permit for what, and who owns the gas line under your yard. Read it and you’ll be able to tell a fair quote from a bad one, whoever you end up hiring.

Plumbing services we run

One team covers residential and commercial plumbing across the Phoenix metro. The main lines of work:

Some work we leave to specialists, and we’ll say so on the call: septic systems, well pumps, fire sprinklers, and grease-trap pumping, which in Arizona is licensed waste-hauler work.

Plumbing pricing, in plain terms

We don’t publish a price list, because plumbing prices that look identical on a website rarely are in a house. A water heater swap in Phoenix is not the same job as one in Scottsdale (one needs a city permit, the other usually doesn’t), and a “clogged drain” can be a hair clog or a root-filled sewer lateral. What we publish instead is how our pricing works:

• The diagnostic fee is stated up front. If a visit carries one, you hear the amount when you book, not on the invoice.
• One flat-rate number, in writing. After someone has looked at the actual leak, line, or heater, you get a written price before any work starts. There’s no hourly meter running while we work.
• Replacement estimates are free. Water heaters, repipes, softeners, and sewer line replacements cost nothing to quote.
• Permits are in the quote. When the city requires a permit and inspection, they’re priced in, not added later.
• You see the options. When both a repair and a replacement are reasonable, you get both prices and the trade-offs, and you choose.

Veterans, active-duty military, and first responders get 10% off, the same standing discount the rest of the company runs.

Phoenix water is hard, and your plumbing shows it

Valley tap water comes from the Salt, Verde, and Colorado rivers and from groundwater, and all of it carries dissolved calcium and magnesium. Utilities report that as hardness, in grains per gallon (gpg) or milligrams per liter; one grain equals 17.1 mg/L. By the U.S. Geological Survey’s scale, anything over 180 mg/L, about 10.5 gpg, counts as very hard. Here is what each city reports:

Three things follow from that table.

• Scale is a water heater’s main enemy here. Minerals settle in the tank and coat the heating elements. The U.S. Department of Energy puts typical tank life at 10 to 15 years and tankless at more than 20, and recommends draining a little water from the tank every few months to clear sediment. In hard water that routine matters more, not less.
• A softener is a choice, not a requirement. Phoenix classes hardness as an aesthetic issue rather than a health standard, and Scottsdale notes that most household water is used outdoors, which is part of why cities don’t soften at the plant. If you want a softener, size it to your water: Mesa, for example, recommends starting at a setting of 16 grains and adjusting from there. Where the city water is already soft, as in parts of Surprise, a softener may not earn its keep, and we’ll tell you so.
• Test before you buy. Hardness varies by zone, by well, and by season. A test at your tap takes a few minutes and settles whether softening, filtration, reverse osmosis, or nothing at all is the right call.

Water heaters and the permit question

When a water heater fails, most people want it replaced the same day, and the first practical question is whether the swap needs a city permit. In the Phoenix metro the honest answer is that it depends on the city, the type of heater, and who does the work.

Codes change, and Tempe and Gilbert are partway through updates, so we check the city’s current rule on every job, pull the permit when one is needed, and put it in the quote. If someone tells you a water heater never needs a permit anywhere in the Valley, that isn’t true in Scottsdale.

Replacing like-for-like is the fastest path. Going tankless trades a higher upfront cost for continuous hot water and a longer life, but in hard water it needs periodic descaling, and a gas tankless unit often needs a larger gas line, which means new pipe sizing and a permit. Heat pump water heaters are the most efficient choice for many homes and need a 240-volt circuit; because Yeti also runs a licensed electrical division (ROC #363423), the circuit and the heater can be one job.

Slab leaks and how we find them

Most Valley homes sit on a concrete slab with water lines running under or through it. Census construction data shows roughly seven in ten new single-family homes finished in the western U.S. in 2025 sit on a slab or similar foundation. When a pipe under the slab leaks, the water has nowhere obvious to go, so the leak shows up indirectly:

• a water bill that jumps with no change in how you use water
• a warm or damp spot on the floor, usually a hot-water line
• the sound of running water with every fixture off
• the leak indicator on your water meter turning while nothing is running
• new cracks in flooring or baseboards, or a musty smell
• a water heater that seems to run constantly

Finding the leak is most of the job. We confirm it with a pressure test, separate the hot side from the cold, and locate it with acoustic and thermal equipment before anyone breaks concrete. Then there are three honest options, and the pipe decides which fits: a spot repair through the slab when it’s one failure on otherwise sound pipe; a reroute that abandons the leaking run and brings new pipe through the walls or attic; or a repipe when more failures are coming. You’ll hear which one we’d choose in your house, and why.

Call your homeowner’s insurance early. Many policies treat finding and fixing the leak differently from the water damage it caused, and the record we leave behind (readings, photos, and the leak’s location) is what an adjuster asks for.

Drains, sewer lines, and monsoon season

A single slow drain is usually a local clog. Several drains backing up at once, or a toilet that gurgles when the washer drains, points to the main line. That’s where a camera earns its keep: it shows whether the trouble is grease, roots at a joint, a sag where the pipe has settled, or a cracked or collapsed section, and the footage goes in your file. It turns “we think” into “here’s the spot.”

Hydro jetting scours grease, scale, and roots off the inside of the pipe far more thoroughly than a cable, and it’s the standard for commercial kitchen lines. When the pipe itself has failed, the fix ranges from replacing one section to replacing the whole line. Trenchless methods, pipe bursting or lining, can replace or reline a sewer lateral with far less digging, which matters in soil full of caliche, where every foot of trench is hard-won. They don’t suit every line, and the camera tells us whether yours qualifies.

Monsoon season brings its own calls: storm surges that overload sewers and push water back up floor drains, roof drains packed with dust-storm debris, and sump and ejector pumps that sit idle for ten months and fail the night they’re needed. A spring check of roof drains and pumps is cheap insurance.

Gas lines and who owns them

If you smell gas, leave the building first, then call your gas utility’s emergency line or 911 from outside. Don’t flip switches or start a car in the garage on the way out.

Short of an emergency, it helps to know where responsibility changes hands. In Southwest Gas territory the utility owns the pipe up to and including the meter. The buried line from the meter to your house, pool heater, or outdoor kitchen is yours, and keeping it leak-free is your responsibility. That customer-owned yard line is also the part 811 locators do not mark, which is why anyone digging for a fence, a pool, or a new line needs to know where it runs. In parts of Mesa the gas utility is the City of Mesa rather than Southwest Gas, so who you call depends on your address.

New gas piping, or an appliance upgrade big enough that the pipe has to be resized, means a permit and a city inspection before the line goes into service. In Phoenix, a meter the utility shuts off for a customer-side leak stays off until the city clears the repair. Swapping an appliance for one the same size, with no piping changes, usually doesn’t need a permit. Every gas line we install or repair is pressure-tested before it goes into service. Arizona’s handyman exemption never covers gas connection work (A.R.S. 32-1121), so gas is licensed-contractor work by law.

Older pipe in older homes

Valley homes plumbed before the mid-1990s may have supply pipe that is reaching the end of its life:

• Polybutylene. Gray plastic supply pipe found in many homes of that era. Failures led to the 1995 Cox v. Shell class action, settled for at least $950 million to replace leaking systems. If your home has it, plan to replace it.
• Galvanized steel. It corrodes from the inside, narrowing the pipe until pressure drops and the water runs rusty.
• Copper with pinhole leaks. Pinholes are documented across the country and researchers haven’t settled on a single cause. One pinhole is a repair; a pattern of them is a repipe conversation.

A repipe replaces the supply lines through the house, usually with PEX or copper, through small openings that get patched rather than walls that get torn out. We’ll show you the pipe, the failure pattern, and a written comparison of repair against repipe before you commit to either.

Commercial plumbing: backflow and grease compliance

Commercial plumbing in the Valley comes with paperwork homeowners rarely see, and two programs drive most of it.

Backflow prevention

Arizona’s rule (A.A.C. R18-4-215, administered by ADEQ) requires backflow prevention assemblies to be tested at least once a year by a certified tester, and each city runs its own program on top of it. Restaurants, medical and industrial sites, irrigation systems, and fire lines are typical targets, and results go to the city on its schedule. Single-family homes are generally exempt unless the city finds a cross-connection, though some cities, Mesa among them, include dedicated residential landscape meters. When a city notice arrives the clock is short: Scottsdale, for example, allows 45 days to repair and pass a retest.

Grease interceptors

Every Valley city regulates fats, oils, and grease from food service, and the pump-out rules differ more than most operators expect:

Most of these cities also require three years of pump-out records and forbid enzymes or other additives as a substitute for pumping. Pumping is licensed waste-hauler work; our side is the plumbing, from interceptor installation and repair, which goes through city plan review on a new restaurant, to jetting the lines that feed it. For property managers and multi-site operators, a maintenance agreement puts backflow tests, line jetting, and water heater service on a calendar instead of an emergency line.

Saving water, and the rebates that help

Several Valley cities pay part of the cost of water-saving upgrades. Programs change, so confirm the terms with your city before you buy, but as of fall 2026:

• Phoenix:$75 per WaterSense toilet (1.28 gallons per flush or less) replacing a toilet of 3 gallons per flush or more, up to two per home, plus $75 for a WaterSense smart irrigation controller.
• Glendale: up to $100 for a WaterSense toilet and $100 for irrigation flow sensors with leak detection.
• Scottsdale: up to $100 for a smart home water monitor that flags leaks, through April 30, 2027.
• Chandler: 50% of the cost of a smart irrigation controller, up to $250.

A leak-detecting shutoff valve, a water monitor, or a low-flow toilet is a small job. We install to the rebate’s specification and leave you the paperwork the city asks for.

The veteran-owned difference

Three trades, one call

Yeti Pros brings HVAC, electrical, and plumbing together, so the jobs that cross trades don’t stall between contractors: a heat pump water heater that needs a new 240-volt circuit, a garbage disposal on a dead switch, a gas line for a new furnace, an AC condensate drain that keeps backing up. One call covers the whole problem.

Licensed, and you can check

Arizona requires a contractor’s license number on its advertising, and anyone can look one up in the Registrar of Contractors’ public license search. Our HVAC license is ROC #363372 (CR-39) and our electrical license is ROC #363423 (CR-11); plumbing is licensed under AZ ROC #341454 (CR-37 Plumbing), held by our plumbing partner Redwood Plumbing Service & Repair LLC. All three show up in the search. A handyman can legally take only small jobs (under $1,000, with no permit required and no gas connection) and must say “not a licensed contractor” in any advertising. If a plumbing quote comes from someone without a license number, ask why.

Warranty in writing

Our workmanship is warranted for two full years, in writing, handed to you at completion. Parts and equipment carry their manufacturers’ warranties, and we register equipment and document the work so a claim stays simple.

Where we work

Plumbing covers the same 23-community footprint as the rest of Yeti Pros, from one dispatch rather than a storefront: Phoenix, Mesa, Scottsdale, Chandler, Gilbert, Tempe, Glendale, Peoria, Surprise, Goodyear, Avondale, Buckeye, Queen Creek, Anthem, Paradise Valley, Fountain Hills, Sun City, Sun City West, San Tan Valley, Apache Junction, Sun Lakes, Casa Grande, and Maricopa.

Response time follows geography honestly. Central cities, where a crew is usually already working nearby, book fastest; the far west and far southeast edges get a real arrival window on the phone rather than an optimistic one. Each city handles permits, water, and gas a little differently, and the sections above call out the differences that change a quote.

Phoenix plumbing questions

Do I need a permit to replace a water heater in Phoenix?

In the City of Phoenix, replacing a water heater with the same kind in a one- or two-family home doesn’t need a permit when a licensed contractor does the work. Moving it, rerouting pipe, or upsizing a gas line does. Scottsdale requires a permit for every replacement, and Gilbert’s exemption excludes tankless units, so the answer changes with your city.

How long should a water heater last in the Valley?

The Department of Energy’s typical range is 10 to 15 years for a tank and more than 20 for tankless. Hard water pushes a tank toward the short end unless it’s flushed regularly, so a 10-year-old tank in an unsoftened Phoenix home is worth checking before it fails.

Do I need a water softener?

Not for safety: cities treat hardness as an aesthetic issue. Softening protects water heaters and fixtures from scale and makes soap work better. Most metro cities run 10 to 17 grains per gallon, but some, like Surprise, deliver much softer water. Test first and size the softener to the result.

What are the signs of a slab leak?

A water bill that jumps without explanation, a warm spot on the floor, running-water sounds with everything off, a water meter leak indicator that keeps moving, or new floor cracks. Shut off the water at the main if you see active water, and get the leak located before anyone breaks concrete.

Who is responsible for the gas line in my yard?

In Southwest Gas territory the utility owns everything through the meter; the buried line from the meter to the house and outdoor appliances belongs to the property owner, and 811 does not mark it. In parts of Mesa the City of Mesa is the gas utility. If you smell gas, leave first and call from outside.

Does my home need backflow testing?

Usually not. Arizona requires annual testing for backflow assemblies that protect the public water supply, which mostly means commercial buildings, irrigation, and fire lines. Single-family homes are generally exempt unless the city finds a cross-connection, though some cities include dedicated residential landscape meters. Your city sends a notice when a test is due.

Can a handyman do plumbing work in Arizona?

Only small jobs. The handyman exemption covers work under $1,000 that needs no permit, and it never covers gas connections. Anything bigger needs a contractor licensed by the Registrar of Contractors, and you can confirm any license number in the ROC’s online search.

Do you handle commercial plumbing?

Yes. Restaurants, offices, retail, and multifamily properties: restroom and flushometer repair, commercial water heaters, drain and sewer service, grease interceptor installation and line jetting, backflow, tenant build-outs, and maintenance agreements that keep compliance work on a schedule.
