Below are answers to some of the most frequently asked plumbing questions we receive from homeowners in Tempe, Scottsdale, and the greater Phoenix area.
Most plumbing experts recommend scheduling professional drain cleaning every one to two years for typical homes. In Tempe and the Phoenix metro area, annual drain cleaning is often ideal due to our hard water conditions. Arizona water frequently exceeds 250 parts per million of dissolved minerals, which accelerates scale formation inside your pipes and reduces drainage capacity over time.
Signs that more frequent cleaning may be needed include slow draining in sinks or tubs, gurgling sounds from your plumbing system, recurring clogs despite DIY efforts, foul odors from drains, and water backing up in multiple plumbing fixtures. Homes with older plumbing, large trees nearby, or heavy daily usage should consider annual service.
Preventative drain cleaning saves money by avoiding emergency repairs and preserves pipe longevity. In desert climate homes, mineral buildup combined with reduced water flow can lead to costly damage or fixture replacements if left unaddressed.
A running toilet typically means water is leaking from the toilet tank into the bowl or the fill valve is not shutting off properly. The most common culprit is a worn or warped flapper, which is the rubber or silicone seal at the bottom of the tank. In Arizona’s dry, hot climate, these rubber components degrade faster due to mineral deposits and low humidity causing materials to become brittle.
Other causes include improper chain length, float mechanism failure, or fill valve problems. You can try basic troubleshooting by placing food coloring in the tank to see if it seeps into the bowl without flushing. Also check for hissing sounds, verify float adjustment, and inspect chain slack.
If these steps do not fix the issue, call a professional plumber. A toilet that runs just 10 minutes daily can waste approximately 4,000 gallons per month, significantly increasing your water bills.
Your garbage disposal is convenient but not designed to handle everything. Avoid putting grease, oil, and fats down the disposal. While liquid when warm, these substances solidify inside pipes and cause stubborn clogs.
Other prohibited items include:
These items strain the disposal motor, damage grinding components, and cause clogs in your plumbing system. This is especially problematic in older Tempe homes with cast iron or narrower PVC pipes.
For proper maintenance, run cold water before, during, and after disposal use. Avoid overloading the unit and chop food scraps into small pieces. Periodically clean with ice cubes or citrus and salt. Consider composting fibrous vegetables or disposing them in regular trash.
A drop in water pressure across all fixtures usually indicates a systemic problem rather than a single fixture malfunction. Common causes include mineral buildup narrowing pipe interiors, hidden leaks reducing available volume, partially closed valves at your main shutoff valve or city meter, debris in supply lines, or a malfunctioning pressure regulator.
In Phoenix, acceptable water pressure ranges between 40 and 100 psi. Homes with pressure exceeding 120 psi may need regulators to prevent damage to appliances and plumbing fixtures.
Arizona’s hard water accumulates scale inside pipes, showerheads, and faucet aerators, gradually reducing flow and pressure. Municipal supply issues from line repairs, low reservoir levels, or construction can also cause temporary drops.
You should seek professional diagnosis if you experience persistent low water pressure even when only one fixture runs, visible scale inside faucets, steadily diminishing pressure over time, or complaints from multiple household members.
Hidden leaks waste water and cause structural damage, often going unnoticed until problems become severe. Warning signs include unexpectedly high water bills despite unchanged usage, damp or water stains on ceilings, walls, baseboards, or flooring. You may also notice sounds of running water when all fixtures are off, musty odors, mold growth, cold spots, or sagging walls.
A simple water meter test can help: turn off all water sources inside and outside your house, then watch the meter flow indicator. If it changes when everything is off, you likely have a leak in your service line. If closing the main shutoff valve stops the movement, the leak is inside your home.
Toilet leaks are a common source. Place inexpensive dye in the tank to see if it appears in the bowl without flushing. Common leak locations in Tempe area homes include under slabs, behind walls, at water heater connections, and in irrigation systems.
Quick action is essential in our desert climate, where moisture damage can degrade structures, encourage mold, waste water, and risk foundation issues.
Water heaters commonly produce mild gurgling or hissing sounds during normal operation. However, popping, rumbling, or hammering noises suggest sediment buildup at the bottom of the tank.
As mineral deposits accumulate, water trapped beneath the sediment heats up, flashes to steam, and bursts upward, causing those concerning sounds. These noises indicate reduced efficiency and potential overheating risk.
Occasional mild noise is typically acceptable, but persistent loud sounds during hot water use suggest heavy sediment accumulation. Regularly flushing the tank can help. In areas with especially hard water like Tempe, semiannual flushes may be beneficial.
Professional inspection is recommended if noise accompanies rusty water, leaks, or temperature fluctuations.
Typical tank water heaters in the Tempe and Phoenix area last between 6 and 12 years, with a median of 8 to 10 years. Our hard water, high ambient temperatures, and heavy daily usage contribute to shorter lifespans. Tankless systems, which heat water on demand and avoid sediment settling, tend to last 15 to 20 years with proper maintenance.
Factors that shorten lifespan include mineral scaling, corrosion from depleted anode rods, poor insulation, and frequent temperature extremes causing expansion and contraction.
Signs that replacement time is approaching include frequent repairs, visible rust or corrosion, leaks at any tank seam, inconsistent hot water, noisy heating, and age over 10 years for tank units.
Maintenance steps that extend lifespan include annual flushing, replacing the anode rod when corroded, installing water softeners, insulating the tank, and keeping units protected from extreme heat.
Yes. Turning off the main water supply when leaving home for a week or more significantly reduces the risk of damage from unchecked leaks. A leaking hose bib, appliance, or plumbing joint can cause flooding, mold, or structural damage. In Arizona’s extreme heat, water leaking inside walls can worsen damage before obvious signs appear.
Preparation steps include:
Additional precautions include having someone check your home periodically, shutting off power to water appliances if possible, and ensuring everyone knows the water shutoff location in case of a plumbing emergency.
That banging sound is called water hammer, a pressure surge created when water flow stops abruptly. The moving column of water suddenly halts, creating a shock wave that rattles through your plumbing system. Loose pipes amplify the noise as they move against framing, and high water pressure intensifies the effect.
Mineral buildup narrowing pipe interiors increases flow velocity before shutoff, making the impulsive pressure even stronger.
Solutions include installing or replacing water hammer arrestors, which are devices that absorb shockwaves. You can also reduce system pressure via a pressure regulating valve, keeping pressure ideally between 40 and 80 psi. Securing or bracing loose pipes helps, as does using valves that close more gradually.
Professional evaluation is necessary if banging continues despite these measures or if pressure fluctuates significantly.
Sewer line backups often result from tree roots intruding into jointed or weakened pipes. Desert landscaping with mature trees creates favorable conditions for root growth seeking moisture, especially when irrigation systems are present. Grease buildup from improper disposal of fats and oils in the kitchen sink also contributes to blockages.
Pipe deterioration is another common cause. Older pipes made of clay, cast iron, or PVC may shift, crack, or collapse, particularly in soil that expands and contracts during monsoon rains. Non-flushable items entering the system worsen backups.
Warning signs include slow drains in multiple fixtures, gurgling toilets, sewage odors, water pooling in yard cleanouts, backups during heavy rains, and wet spots in your yard above underground sewer lines.
Professional inspection using sewer cameras can identify problems. Cleaning may involve hydro jetting, pipe relining, or replacement. Preventative measures include clearing grease, keeping landscaping roots away from lines, and avoiding flushing non-flushables.
While chemical drain cleaners seem convenient for small clogs, frequent use carries significant risks. Harsh alkaline or acidic chemicals can damage pipe finishes, degrade seals and joints, and corrode metal pipes. For homes in the Tempe area with aged plumbing systems, chemical damage tends to be especially severe.
Safer alternatives for minor clogs include mechanical removal using plungers or drain snakes, enzymatic or bacterial cleaners, or hot water with baking soda and vinegar.
For persistent or recurring clogs, professional drain cleaning techniques such as snaking or hydro jetting provide more effective and safer results. A professional plumber can also use camera inspection to identify underlying issues and prevent further damage.
Although freeze events are uncommon in Arizona, pipes in exposed locations remain vulnerable during cold snaps. Areas most at risk include attics, crawl spaces, exterior walls, and hose bibs.
To prevent frozen pipes:
If pipes do freeze, never use an open flame. Instead, apply heat using a hair dryer or heating pad, starting near the faucet and working outward to prevent pressure buildup. If a pipe bursts, shut off the main water supply immediately and call a plumber immediately.
Repair versus replacement decisions depend on cost, age, frequency of failure, efficiency, and safety. Repair is efficient for minor plumbing issues like replacing a flapper, fixing a gasket or seal, addressing a small leak, or adjusting a ball valve.
Replacement makes more sense when repeated failures occur, when components are structurally compromised or corroded, or when efficiency gains are significant. Upgrading to low flow fixtures or a more efficient water heater can provide long-term savings.
Long-term value often favors replacement when maintenance costs approach or exceed replacement cost. New plumbing fixtures typically offer warranties, improved efficiency, healthier water flow, and better reliability. Using newer materials like PEX instead of galvanized steel can reduce corrosion and leaks for years to come.
Certain plumbing problems require professional expertise. Call a plumber for sewer backups, hidden leaks within walls or under slabs, water pressure issues affecting your whole water system, water heater leaks or gas connections, major fixture replacements, water hammer issues, frozen pipes, and any situation involving safety risks with gas or electricity.
Risks of DIY repairs include exacerbating damage, voiding warranties, creating safety hazards, improper sealing causing future leaks, and incorrect sizing or connections. Many plumbing projects also require permits and code compliance that licensed plumbers ensure.
For emergencies like burst pipes, sewage backups, or gas leaks, contact a professional immediately. If a problem persists despite your troubleshooting efforts, professional plumbing services provide the expertise and tools to diagnose and fix issues correctly the first time.
