Plumber in Tempe, AZ: Older Homes, Rentals, and Hard Water
Tempe incorporated in 1892; about four in 10 of its homes were built before 1980, and more than half of its households rent. Near campus, in ZIP 85281, three in four do. So the calls we get from Tempe are about older houses, rental turnovers, and hard water, and often all three at once.
We are American Discount Plumbing, a family-owned, Christian company in business since 2000. We work out of the northwest Valley, so planned Tempe work is scheduled in advance, and the owner, Pavel Farcas (Paul), comes himself.

Does Your Tempe Water Heater Job Need a Permit?
Under Tempe's building code, how a water heater job is planned depends on one question: is anything changing? In a detached house, duplex, or townhome, replacing a water heater that serves a single home with one of the same type and fuel in the same spot does not require a city permit. For an electric unit, the new one also needs the same amperage rating or a lower one. The same exemption covers replacing a water softener or treatment unit where the old one stood. Change the type, the fuel, or the location, and a permit applies. Any new or altered gas piping needs one too.
Tempe adopted the 2024 editions of the plumbing and fuel gas codes effective July 1, 2026, with the older editions still accepted for applications through the end of 2026. Permits are applied for online through the city's Citizen Access Portal. When a job needs one, we tell you at the quote, include it in the plan, and schedule around the inspection.

What Comes Out of Tempe's Taps
Hardness that changes with the season
The City of Tempe blends three sources: water from the Salt and Verde rivers, delivered by SRP, which makes up most of the supply; groundwater from its own wells; and Colorado River water from the Central Arizona Project. The city's 2025 water quality report lists the average hardness at 12.3 grains per gallon, with a range of 10.4 to 32.6 grains per gallon. The blend shifts with the seasons, and the city notes the Verde carries more of the minerals that make water hard.
That range is why we ask before sizing or setting a softener. A unit set for the average can fall behind when harder water comes through. The same scale that coats a showerhead settles as sediment inside a tank water heater and inside the heat exchanger of a tankless unit, which is why a tankless unit here needs regular descaling. Ours is a flat $250.
Chlorine taste
Tempe disinfects with free chlorine and ultraviolet light. Households that notice chlorine in a glass of water can install a carbon filter at the kitchen sink or a reverse osmosis system for drinking water. The city itself says home treatment is not needed for safety, and that people who add it usually do so for taste or hardness.
PFAS, in plain numbers
The city reports that in 2025, some samples showed PFOS and PFOA above the federal limits set by the EPA in 2024, with PFOS as high as 33 parts per trillion against a limit of 4, while the averages were below detection. The compliance date is April 2029, and in May 2026 the EPA proposed extending it to 2031. Tempe says it is in compliance today, has kept three affected wells out of service since 2016, and is designing treatment ahead of the deadline. Households that prefer not to wait until 2029 or 2031 can install a reverse osmosis system certified for PFAS reduction under the kitchen sink; the certification should specify the exact model being installed.
Tempe Homes by ZIP Code
Census build-year figures for Tempe's ZIP codes show how much the housing changes from north to south. ZIP code lines do not exactly follow city limits, so treat them as a guide and check your own house's build year in the county record.
North Tempe and around ASU (85281)
The most mixed part of the city. There are 1950s- and 1960s-era houses on the older streets, and nearly four in 10 homes here were built in 2000 or later. About a third of all homes in this ZIP code are in buildings with 50 or more units. About three in four households rent. Expect fixture and water heater calls in older rentals, and commercial plumbing in the newer mixed-use buildings.
West and central Tempe (85282)
The oldest housing in the city by share: close to six in 10 homes here were built before 1980, most of them in the 1960s and 1970s. This is ranch-house country, and Date Palm Manor, one of the city's designated historic districts, is here. Original shutoff valves, tired fixtures, and gas connectors put in decades ago are common finds.
East-central Tempe (85283)
The 1970s are the biggest decade here, with nearly four in 10 homes from that era and a mix of owners and renters. Many of those houses have replaced their water heaters by now, but the shutoff valves and supply connections behind the tank can still be the originals.
South Tempe (85284)
Mostly 1980s and 1990s homes, and more than eight in 10 are owner-occupied, the highest share in the city. It is also the part of Tempe with the fewest houses built before 1980, so the painted-surface limit that shapes some jobs further north rarely comes into play here.
Homes built before 1978: we only take on work that leaves painted surfaces undisturbed. If a repair would require opening a painted wall, that part goes to a lead-safe-certified contractor you hire directly; we do not perform or arrange it, and we tell you before anything is scheduled.
Plumbing in a Tempe Historic District
Tempe has designated historic districts, including Roosevelt Addition, Borden Homes, Date Palm Manor, and Tomlinson Estates, all of which are post-war neighborhoods from the late 1940s to the early 1960s. Properties on the Tempe Historic Property Register get design review from the city's Historic Preservation Office for exterior changes.
Most plumbing never reaches that review. The office's own list exempts interior plumbing that does not show on the outside, underground water, sewer, and gas lines, and the replacement or repair of water heaters and softeners in the same location. What can need review is a change people see: equipment moved to a new spot on the outside of the house, or new exterior piping that does not match what is there. The review itself is free, and a building permit may still apply on its own terms. University Park and several other older neighborhoods appear on the city's map as eligible for designation rather than designated.
For Tempe Landlords and Property Managers
About 58% of Tempe households rent, and roughly half of the city's housing units are in buildings with two or more units. That makes Tempe a city of landlords as much as homeowners, and the type of building a rental sits in determines whether a water heater swap requires a permit. The same-spot exemption covers houses, duplexes, and townhomes serving one unit, so a rental house can get its new tank in the gap between one lease and the next, with no permit wait.
Tell us move-out day, who signs off, and who will let us in; the quote goes to the person who signs off. Anything found beyond the original call is returned to that person before any further work is done. Apartment buildings and commercial space fall outside that exemption, so those replacements are planned around a permit from the start.
Tempe also offers a multi-family indoor fixture rebate of up to $5,000 per property for items such as high-efficiency toilets, showerheads, and aerators. Tempe Water Conservation administers it.

Two Calls That Come Up Often in Tempe
These describe common patterns in the city's housing, not specific customers.
The swap that turned into an upgrade
A 1970s house needs a new water heater, and the owner asks about going tankless while the old tank is coming out anyway.
Both are fair choices. The tankless route brings in the permit and gas work shown in the table above, so you get two written prices, one for each route, and make the call yourself.
The tank that quits during turnover week
A rental house sits empty for a week between leases. The water heater that seemed fine for the last tenant starts leaking at the base, and nobody notices until the new tenant moves in.
Move-out week is a good time to check the tank's date and look for rust or a dripping relief valve, since a replacement then does not disrupt anyone.
Tempe Plumbing Questions
Still have a question? Call Pavel (Paul) directly and get a straight answer, no phone tree.
Yes, homes and businesses within Tempe. We do not currently serve Mesa, Gilbert, Chandler, Apache Junction, or Queen Creek, so if you are close to the city line, give us your address when you call, and we will confirm.
The city's high-efficiency toilet rebate covers half the purchase price, up to $75 per toilet, for WaterSense models that use 1.28 gallons per flush or less, with a limit of two per single-family home. Confirm the current terms with Tempe Water Conservation before you buy.
Not at the moment. The city's rebate list covers toilets, irrigation, gray water systems, grass removal, and fixtures for multi-family and commercial properties. Our own discount does apply: 10% off any water heater installation.
The City of Tempe links that odor to water heaters set too low or left sitting unused. A flush and, on some tanks, a different anode rod usually clear it up. The city recommends having a licensed plumber check the heater's settings, and we do that on the same visit.
There is a $75 service fee only if no work is done. If you go ahead with the repair, there is no service fee.
One Name on Every Tempe Job
One accountable person
A landlord with three properties and a homeowner with one old house want the same thing: to know who did the work and to reach that person if something is wrong. Here, that is Pavel Farcas (Paul), every time. The company holds AZ ROC license #150707 and is licensed, bonded, and insured.
By appointment
Planned work in Tempe is easiest to book ahead: a water heater replacement, a set of fixtures, a gas line for a new range. You get a time to plan around. If water is on the floor right now, shut the main off first and call; Pavel (Paul) will tell you by phone where that valve usually is in a house like yours, and plainly whether same-day is possible.
Worth Knowing Before Your Next Tempe Plumbing Job
Set the softener for the hard end of the range
The City of Tempe publishes its water quality report every year, with average hardness and the full range in grains per gallon. Because the blend shifts, set the softener with some room above the average, and look again when a new report comes out.
Turn on leak alerts in WaterSmart
Tempe's smart meters report hourly use to the city's WaterSmart portal, which can alert you to unusually high use or a possible leak. Customers who receive an alert can request a leak consultation from the city's water conservation staff. A running toilet or a leak under a slab often shows up there before it shows up on the bill.
Buy the rebate-eligible toilet
If a toilet is due for replacement, choose a WaterSense model rated at 1.28 gallons per flush or less, and keep the receipt. That is what the city's rebate requires, and it saves water on every subsequent flush.
