24/7 Plumber in Tempe, AZ

Tempe is an older, denser city than most of the East Valley. Much of it was built from the 1960s through the 1980s, from mid-century neighborhoods like Maple-Ash and Mitchell Park near ASU to the ranch homes of south Tempe, plus newer condos around Tempe Town Lake. Older homes often still have original water heaters, shut-off valves, and in some cases galvanized supply lines that rust from the inside. U.S. Census data puts the median Tempe home's build year at 1984, the oldest housing of any East Valley city we serve.

A big share of Tempe homes are rentals, many near ASU, and they turn over every summer. When something breaks, the tenant, the owner, and sometimes a property manager all need to know what happened and what it costs. We explain the problem in plain terms, quote it before starting, and can send photos to whoever approves the work. We serve 85281, 85282, 85283, and 85284.

Common Tempe plumbing issues we see every week:

• Burst supply lines, failed water heaters, and backed-up drains that need same-day help
• Hardness that averages 12.3 grains per gallon but reaches 32.6, according to Tempe’s 2025 report
• Original valves, water heaters, and galvanized lines in homes from the 1960s through the 1980s
• Rental repairs that need clear photos and pricing for the owner or property manager

Whether you're a Tempe homeowner, a landlord, or a tenant with water on the floor, call OX Plumbing. We'll be there fast.

Do these first, then call us:

• Water spraying or pooling: close the main shut-off valve, usually where the water line enters the house or in a box near the curb.
• Water heater leaking: turn off its cold-water valve on top, and switch off the gas or the breaker.
• Toilet or drain backing up: stop using water in the house until the line is cleared.
• In a rental: tell the owner or property manager right away, and take photos for them.

Then call OX Plumbing. See our emergency plumbing page for what we handle around the clock.

Tempe's 2025 water quality report lists hardness averaging 12.3 grains per gallon, with readings from 10.4 to 32.6. Most of Tempe's water is Salt and Verde River water from the Salt River Project, which supplied about 12 billion of the 15 billion gallons Tempe delivered in 2025. Eight city wells supplied about 14%, and Colorado River water about 7%. Well water runs much harder, which is why the range is so wide.

If your softener is set for the average, harder days still leave scale in water heaters, tankless units, and faucet cartridges. We check softener settings and install water treatment systems sized for your home. See water softeners in Tempe.

Tempe's water meters record usage every hour, and customers can see it at tempe.gov/WaterSmart. If your use never drops to zero overnight, even when nobody is running water, something is leaking: a toilet flapper, an irrigation valve, or a line under the slab.

We find hidden leaks with electronic and acoustic equipment before opening walls or floors. See leak detection and slab leak repair. In older homes with repeated leaks, a repipe can cost less than patching one leak after another.

Rental water heaters often run until they fail, and in Tempe's hard water that's usually sooner than expected. Rusty hot water, a damp base, or rumbling while heating are the warning signs. We service tank and tankless models, gas or electric, and can send the owner a replacement quote with photos before any work starts. See our water heater services.

Older Tempe neighborhoods have mature trees, and their roots find their way into sewer lines. When a drain keeps backing up, a camera inspection shows the cause, and drain cleaning or hydro jetting clears it. If the pipe itself is cracked or broken, see sewer line repair in Tempe.

We also take care of:

• Running toilets, dripping faucets, and worn shower valves
• Angle stops, main shut-offs, and outdoor hose bibs
• Garbage disposals, dishwasher and washer hookups
